Title:

END-USER DEVELOPMENT FOR KNOWLEDGE SHARING - A Collaborative Web Mapping Application in the First Aid Domain

Authors:

Daniela Fogli and Loredana Parasiliti Provenza

Abstract: This paper describes FirstAidMap, a collaborative web mapping system for creating, managing and sharing territorial knowledge that can be useful in case of emergencies. The system arises from a design experience we have carried out with representative end users belonging to an association for public assistance and first aid. Volunteers of this association, and specifically ambulance drivers, need to know the characteristics of the territory where they ensure their assistance, in order to reach a given place quickly and in a safe manner. This knowledge is often tacit and usually distributed among the members of the association. Currently, to cope with this problem, paper-based maps are the only means to spread and share knowledge within the association; while training sessions are regularly taken to provide drivers with information about the dangers existing in the territory and possible viability modifications. Representative volunteers participated in the design of FirstAidMap and in the study of end-user development functionalities that could make all volunteers able to contribute their own knowledge and share it with the other volunteers. The resulting system engages and motivates users to participate in map shaping and, at the same time, reinforces the sense of community and individual awareness.

CRIMEFIGHTER ASSISTANT - A Knowledge Management Tool for Terrorist Network Analysis

Authors:

Uffe Kock Wiil

Abstract: A terrorist network is a special kind of social network with emphasis on both secrecy and efficiency. Such networks (consisting of nodes and links) need to be analyzed and visualized in order to gain a deeper knowledge and understanding that enables network destabilization. Previous research on terrorist network analysis has to a large degree focused on analysis of nodes. This paper presents the CrimeFighter Assistant, a novel knowledge management tool for terrorist network analysis. CrimeFighter Assistant treats links as first class objects and provides a better balance between network, node, and link analysis.

A SECURE AND EFFICIENT ORDER PRESERVING ENCRYPTION SCHEME FOR RELATIONAL DATABASES

Authors:

Hasan Kadhem

Abstract: Encryption is a well-studied technique for protecting the confidentiality of sensitive data. However, encrypting relational databases affects the performance during query processing. Preserving the order of the encrypted values is a useful technique to perform queries over the encrypted database with a reasonable overhead. Unfortunately, the existing order preserving encryption schemes are not secure against known plaintext attacks and statistical attacks. In those attacks, it is assumed that the attacker has prior knowledge about plaintext values or statistical information on the plaintext domain. This paper presents a novel database encryption scheme called MV-POPES (Multivalued - Partial Order Preserving Encryption Scheme), which allows privacy-preserving queries over encrypted databases with an improved security level. Our idea is to divide the plaintext domain into many partitions and randomize them in the encrypted domain. Then, one integer value is encrypted to different multiple values to prevent statistical attacks. At the same time, MV-POPES preserves the order of the integer values within the partitions to allow comparison operations to be directly applied on encrypted data. Our scheme is robust against known plaintext attacks and statistical attacks. MV-POPES experiments show that security for sensitive data can be achieved with reasonable overhead, establishing the practicability of the scheme.

MIKROW - An Intra-enterprise Semantic Microblogging Tool as a Micro-knowledge Management Solution

Authors:

Guillermo Álvaro, Carmen Córdoba, Víctor Penela, Michelangelo Castagnone and Francesco Carbone

Abstract: One of the biggest bottlenecks in Knowledge Management systems where end-users are supposed to actively participate is precisely the hurdles they encounter that discourage them for keeping involved. On the other hand, the so-called Web 2.0, where users participate in an active manner, willingly generating new content, has been adopted by companies for their internal processes in the so-called Enterprise 2.0. In particular, microblogging systems have been embraced as a way of fostering internal communication within the enterprise boundaries. In this paper, we propose a lightweight framework for Knowledge Management based on the microblogging paradigm, and supported by the use of semantics, both internally with the use of domain ontologies, and externally by leveraging the Linked Data paradigm. A current implementation and evaluation are also discussed.

REAL-TIME INTELLIGENT DECISION SUPPORT IN INTENSIVE MEDICINE

Authors:

Filipe Portela, Manuel Santos, Marta Vilas Boas and Fernando Rua

Abstract: Daily, a great amount of data that is gathered in intensive care units, which makes intensive medicine a very attractive field for applying knowledge discovery in databases. Previously unknown knowledge can be extracted from that data in order to create prediction and decision models. The challenge is to perform those tasks in real-time, in order to assist the doctors in the decision making process. The Data Mining models should be continuously assessed and optimized, if necessary, to maintain a certain accuracy. In this paper we present the INTCare system, an intelligent decision support system for intensive medicine and the way it was adapted to the new requirements. Some preliminary results are analysed and discussed.

SEMANTICS AND MACHINE LEARNING FOR BUILDING THE NEXT GENERATION OF JUDICIAL COURT MANAGEMENT SYSTEMS

Authors:

E. Fersini, E. Messina and D. Toscani

Abstract: Information and Communication Technologies play a fundamental role in e-justice: the traditional judicial folder is being transformed into an integrated multimedia folder, where documents, audio and video recordings can be accessed and searched via web-based judicial content management platforms. Usability of the electronic judicial folders is still hampered by traditional support toolset, allowing search only in textual information, rather than directly in audio and video recordings. Transcription of audio recordings and template filling are still largely manual activities. Thus a significant part of the information available in the trial folder is usable only through a time consuming manual search especially for audio and video recordings that describe not only what was said in the courtroom, but also the way and the specific trial context in which it was said. In this paper we present the JUMAS system, stemming from the JUMAS project started on February 2008, that takes up the challenge of using semantics towards a better usability of the multimedia judicial folders. The main aim of this paper is to show how JUMAS has provided the judicial users with a powerful toolset able to fully exploit the knowledge embedded into multimedia judicial folders.

INTEGRATING CURRENT PRACTICES AND INFORMATION SYSTEMS IN KM INITIATIVES - A Knowledge Management Audit Approach

Authors:

Oscar M. Rodríguez-Elias and Cesar E. Rose-Gómez

Abstract: Researchers and practitioners in the field of knowledge management have observed the need of performing studies to understand the context and specific knowledge workers’ needs before proposing strategies or systems that may not be entirely useful for organizations, resulting in costly and unsuccessful knowledge management projects. Different approaches have been proposed to face this problem, such as process engineering techniques to integrate knowledge management in business processes, and also knowledge audits to identify the knowledge and knowledge problems in organizations. This paper draws on the idea of the knowledge audit to propose a methodology for knowledge management audits, which integrates process engineering techniques and the main tasks of knowledge audits. The methodology was developed based on one of our previous works, literature review, and our own experience in field studies. The methodology, its constitutive phases and main tasks, together with some aspects about its use in field studies, including benefits and weaknesses, are described.

SUPPORTING DIGITAL COLLABORATIVE WORK THROUGH SEMANTIC TECHNOLOGY

Authors:

Simon Scerri

Abstract: Taking advantage of the fact that knowledge exchanged within digital working environments can be made persistent, a lot of research has strived to make sense of the ongoing communications in order to support the participants with their shared management. Semantic technology has been applied for the purpose as it ensures a shared understanding of the underlying collaboration, between both humans and machines. In this paper we demonstrate how, coupled with appropriate information extraction techniques, robust knowledge models and intuitive user interfaces; semantic technology can provide support for digital collaborative work. As a virtual working environment, e-mail was a natural contender for testing our hypothesis. Taking a workflow management-based approach, we demonstrate how semantics can indeed support email-based collaboration via Semanta – a tool extending popular email clients enabling semantic email. In particular we present a novel workflow-based email visualisation, the tool’s summative evaluation, and discuss the odds of semantic applications like Semanta evolving beyond research prototypes.

EXPERIMENTAL EVIDENCE ON DATA WAREHOUSE FRAGMENTATION AND ALLOCATION IN A DISTRIBUTED CONTEXT

Authors:

Tekaya Karima

Abstract: Since a relational data warehouse has the same physical structure as a classical database, it can enjoy all the benefits realized during the past in distributed databases such us data availability, simplicity, rapid local data access and transparent access to remote sites. So, it would be interesting to test its decentralization by adapting the most adequate fragmentation and allocation technique. In this paper, we present a data warehouse fragmentation and allocation approach in a distributed context. We conduct first, computation studies using a mathematical cost model. Then, we test our approach on a real data warehouse by using the APB1 benchmark data set on Oracle11G.

THE IMPACT OF TRUST AND INTERACTIVITY ON INTENSIFYING CUSTOMER LOYALTY FOR CRM

Authors:

Alireza Faed

Abstract: Customer relationship management (CRM)is one of the most significant tools that a company can utilize in order to better acquire customers, keep them for a long term and always provide them with premium values. In addition, CRM is beneficial for labour saving purposes through efficiencies especially when consolidating with some Internet-enabled applications. Companies employ CRM in an attempt to increase their profitability and simultaneously enhance their customer interactions and loyalty. Nevertheless, in order to avoid a negative response to the relationship with the customers, companies must incorporate two important aspects of CRM to enhance customer loyalty and improve the effective usage level of CRM are trust and interactivity. In order for CRM to be productive and responsive it is important that issues such as trust and interactivity are appropriately analysed and addressed. Companies must increase their efforts to support a customer’s loyalty by creating and promoting various values including interactivity and so on. In this paper, we propose a conceptual framework to support Internet-CRM in order to optimize CRM system and strategies by increasing the levels of value proposition, brand credibility, interactivity and trust. We also provide a case study based on this proposed conceptual framework.work.

AN INTEGRATED APPROACH IN DEVELOPING KNOWLEDGE MANAGEMENT PROCESS CAPABILITIES

Authors:

Mohamed Khalifa and Kathy Ning Shen

Abstract: It is widely accepted that effective KM requires both infrastructural and process capabilities. However, very little research has been conducted to understand how either kind of capabilities are developed. In this paper, we focus on KM process capabilities, identify and empirically examine the important factors in that influence the development of KM process capabilities. Particularly, relying on the institutional theory and technology-task fit theory, we propose that KM process capabilities are driven by both organizational, i.e., leadership and organizational culture, and technological factors i.e., technology fit. An empirical study was then conducted with KM practitioners to validate the hypotheses. On the theoretical side, this study entangles the relationship between two KM capabilities proposed in (Gold et al., 2001). On the practical side, the results provide valuable guidelines for developing KM process capabilities, with a balance between both managerial and technical infrastructures.

INCREMENTAL USER MODELING WITH HETEROGENEOUS USER BEHAVIORS

Authors:

Rafael Alonso

Abstract: We describe an innovative approach for incrementally learning user interests from multiple types of user behaviours or events. User interests are reflected in the concepts and their relations contained in these events. The concepts and relations form the structural elements of a user interest model. The relevance of each structural element is signified by a weight. Our user modeling algorithm builds dynamic user interest model with two concurrent processes. One process grows the model by intelligently incorporating concepts and relationships extracted from user events. Another process adapts the weights of these model elements by applying a novel combination of two mechanisms: reinforcement and forgetting, both important in modulating user interests. Our modeling algorithm supports incremental and real time modeling, and readily extends to new types of user events. One interesting application of user interest models is to identify a virtual interest group (VIG), which is an ordered set of other system users who exhibit interests similar to those of the target user. As a result, we can evaluate our user modeling algorithm through a VIG identification task. In a formative NIST evaluation using intelligence analysts, we achieved 95% VIG identification precision and recall.

APPLYING FUSION TECHNIQUES TO GRAPHICAL METHODS FOR KNOWLEDGE BASED PROCESSING OF PRODUCT USE INFORMATION

Authors:

Susanne Dienst and Fazel Ansari

Abstract: In this paper the processing and modelling of product use information raised by graphical methods on the basis of a praxis and application scenario. Product Lifecycle Management (PLM) ensures a uniform data basis for supporting numerous engineering and economic organisational processes along the entire product life cycle – from the first product idea to disposal or recycling of the product respectively. The Product Use Information (PUI) -e.g. condition monitoring data, failures or incidences of maintenance- of many instances of one product type is generated in the product use phase. The processing and modelling of PUI raised by graphical methods like Bayesian Networks. In accordance, the product use knowledge leads back to the product development phase and is used for discovering room for product improvements of the next product generation. Therefore the PUI of the different instances should be aggregated by applying fusion techniques to deduce/achieve generalized product improvements for a product type. As a result this paper reveals a novel approach of applying new feedback mechanism of PLM for product improvements.

ADAPTATION OF MATHEMATICAL DOCUMENTS - Exploring Document Structures, Metadata, and Context for the Generation of User-specific Documents

Authors:

Christine Müller

Abstract: The paper proposes a framework that explores document structures, metadata, and context to adapt mathematical documents on three layers - the content, structure, and presentation layer. On the presentation layer mathematical expressions are rendered according to a user context (defining, e.g., the users’ preferred convention, language or discipline). On the content layer, appropriate paragraphs of texts are selected that best suit the users’ individual information need as well as narrative and semantic context. On the structure layer, these content parts are arranged appropriately, while taking semantic and narrative interdependencies between parts into account. Technically, the framework models documents as dependency graphs, where nodes correspond to any addressable part of a document and edges denote narrative and semantic dependencies. To allow for the adaptation on all three document layers, these dependency graphs are enriched with presentational, content, and structure variants. Finally, the enriched graphs are processed to generate a user-specific document. Users can guide this adaptation process by prioritising their individual constraints, narrative or semantic context.

USING ROLE-PLAYS TO ACQUIRE PROCESS-ORIENTED KNOWLEDGE IN ENTERPRISES

Authors:

René Börner and Michael Leyer

Abstract: Process-oriented enterprises are expected to be more successful than traditional functional-oriented ones. Consequently, more and more companies want to become process-oriented. But to reach this goal a basic change of mind towards more process-oriented thinking of a company’s employees is required. Therefore, the adequate support of employees to acquire process-oriented knowledge is crucial for organisations. Unfortunately, the necessary knowledge is tacit knowledge which is not easy to acquire. While formal learning or training programs deliver explicit knowledge and skills, it is much more challenging to generate implicit or tacit knowledge out of everyday work activities. In order to help employees to acquire and apply tacit knowledge, a role-play based simulation program, named KreditSim, has been developed. This kind of simulation allows for a learning environment closely related to the actual workplace. The case of KreditSim shows how this coaching method actively involves employees and improves awareness of process-oriented thinking. The participants gain the necessary process-oriented knowledge by a guided improvement of a given functional-oriented process with deficiencies.

SUPPORTING REUSE OF KNOWLEDGE OF FAILURES THROUGH ONTOLOGY-BASED SEMANTIC SEARCH

Authors:

Steven B. Kraines and Weisen Guo

Abstract: In order to increase the effectiveness of sharing and reusing knowledge about failures, we have applied the expert knowledge ontology-based semantic search system, EKOSS, to the “failure knowledge database”. An ontology based on description logics is used as a formalized knowledge representation language for creating semantic statements describing 212 of the JST failure cases. Using the EKOSS reasoner, the similarity be-tween a search statement giving the conditions of a new project or project design and the semantic statements describing failure cases can be quantified by inferring specific semantic relationships between entities involved in the case. The corpus of semantic statements is described, and results of applying the EKOSS semantic search to the semantic statements are analyzed. Finally, the effectiveness of the SCINTENG ontology for expressing the underlying failure mechanisms of the cases is discussed.

KNOWLEDGE MANAGEMENT USING CLUSTERS IN VANETS - Description, Simulation and Analysis

Authors:

C. Caballero-Gil

Abstract: Vehicular Ad Hoc Network (VANET) is a type of mobile network that allows Knowledge Management of the road providing communication among nearby vehicles and between vehicles and nearby fixed roadside equipment. The lack of centralized infrastructure and high node mobility and number of vehicles generate problems such as interrupting connections, difficult routing, security of communications and scalability. Clusters are here proposed as a solution to avoid data collisions by decreasing the number of connections exchanged among vehicles and to reach this goal, nodes must cooperate, and form or join clusters depending on their state. This paper provides a global vision of the life cycle of cooperative nodes who form clusters and a description of how to deal with the information within a cluster. Simulation results show that the proposed scheme reduces the number of communications, avoiding data loss due to collisions. This paper provides a full description of each cluster management process and of how to deal with the information within a cluster.

ONTOLOGY-BASED RAILWAY INFRASTRUCTURE VERIFICATION - Planning Benefits

Authors:

Michael Lodemann and Norbert Luttenberger

Abstract: Planning new railway infrastructures is a complex process. We present an approach where the formalization of expert knowledge regarding the railway domain is motivated in order to improve the planning process. By applying ontologies as a representation of railway related knowledge we are able to make the coherencies of infrastructural elements explicit. Furthermore the integration of an ontology-based rule language provides the possibility of a semi-automated integrity verification of static infrastructure and safety components. Semantical inconsistencies potentially leading to unsafe conditions regarding train operations can be spotted within this verification process. This combination of conceptualization and correlation rules tends to be applicable for the creation of a formal and consistent model of specific railway infrastructures which are to be planned.

THE INFLUENCE OF SOCIAL NETWORKS ON KNOWLEDGE MANAGEMENT FOR INNOVATION IN LIFE-SCIENCE DISCOVERY NETWORKS

Authors:

Claire Gubbins and Lawrence Dooley

Abstract: The competitiveness and sustainability of a modern organisation depends on its ability to innovate. It is increasingly accepted that knowledge, skills and competencies are the key drivers of innovation. Access to the latest information can provide critical competitive edge for organisations’ innovation efforts. Social networks are found to promote organisational and collective learning and are a significant source of knowledge which subsequently leads to innovation. The paper aims to introduce social network analysis as a useful methodology for organisations and managers to use to analyse how collaboration for knowledge management for innovation efforts is accomplished. Social network analysis (SNA) facilitates analysis of relationships among actors in a network. It describes a number of social network factors that are useful in analysing overall network structures, network content, the characteristics of interactions and identifying the impact they have on knowledge management for innovation efforts. This will illuminate the mechanisms through which collaboration for innovation is accomplished. Three case studies of a knowledge network within the life sciences sector are utilised to conduct an exploration into how knowledge is managed through social networks for innovation.

A HIERARCHICAL VENDOR SELECTION OPTIMIZATION TECHNIQUE FOR MULTIPLE SOURCING

Authors:

Mariagrazia Dotoli and Marco Falagario

Abstract: The paper addresses a crucial objective of the strategic function of purchasing in supply chains, i.e., vendor rating, proposing a hierarchical model for supplier business intelligence. A three-level optimization process for supplier selection in a multiple sourcing strategy context is proposed. First, the Data Envelopment Analysis, the most widespread method for supplier selection, is used to evaluate the efficiency of suppliers. Second, the well-known Analytic Hierarchy Process is applied to rank the efficient suppliers given by the previous step. Third, a linear programming problem is solved to find the quantities to order from each efficient supplier. We show the model effectiveness on a simulated case study of a C class component.

EXTERNALIZATION METHOD AND ITS EVALUATION OF KNOW-HOW INFORMATION FOR CARE PLANNING PROCESSES BY AWARENESS OF NOVICES

Authors:

Kaoru Eto and Minoru Mukuda

Abstract: The know-how information to perceive care needs based on assessment results is crucial to improve the quality of care service. We developed a know-how information sharing system for care planning processes. We propose a method that externalizes and shares know-how information by visualizing and observing care plans drawn by experts in various forms that allow beginners to notice the differences between the plans of novices and experts. Sharing know-how information is possible by recording, accumulating, and referring to what has been observed when comparing documents. This system two-dimensionally maps and visualizes each document based on the differences among documents perceived by the assessment results. Externalizing and sharing know-how information are supported by visualization. Trial results in a care facility confirmed that our system effectively externalized and shared know-how information. Improvement in individual capabilities, organization growth, and the possibility of rejuvenation were confirmed by using our system.

ONTOLOGY EDITING TOOL FOR INFORMATION SECURITY AND HUMAN FACTORS EXPERTS

Authors:

John Mace

Abstract: Currently ontology development is facilitated by generic ontology editing tools which accommodate ontology experts, and not necessarily those individuals whose knowledge requires capture. Furthermore the process of knowledge capture is time consuming, error prone and requires appropriate technical skills. We propose a graphical editing tool for ontology development which simplifies knowledge capture. To demonstrate the tool’s potential this paper explores the need for information security and human factors experts to capture their related knowledge in a dedicated ontology. Population of such an ontology would provide supporting information to enable organisations to make more well informed security policy decisions. Tailoring the tool for information security and human factors experts allows them to produce ontology content without being familiar with ontology construction and technologies. The tool is intuitive, requires no ontology component configuration, and provides mechanisms to guide users and reduce the potential for errors. Our tool allows information security domain experts to develop and extend the ontology, and organisations to tailor ontology content to their own requirements.

MODELING KNOWLEDGE FLOWS IN SOFTWARE PROJECT MANAGEMENT PROCESSES

Authors:

Brenda Leticia Flores Rios

Abstract: Software development SMEs interested in launching a KM initiative or software project managers working on taking their KM initiative to the next level, need to assess what strategy will best fit their knowledge needs and which will be the most likely to succeed based on their social, cultural and technological aspects. Taking into account the social and cultural characteristics of Mexican software development SMEs, the Mexican Ministry of the Economy encouraged the creation and adoption of the NMX-I-059-NYCE-2005 Standard. The main goal of this standard is help SMEs become more competitive and reach higher maturity levels. However, SMEs adopting or implementing this standard sometimes experience difficulties and problems in their daily software activities. In this paper, we model ongoing knowledge flows as an adaptation to Choo’s framework, applied to the project portfolio management process as defined in such standard. In addition, we present some strategies followed by Mexican software development SMEs while conducting a SPI program for maturity levels 1 and 2.

UNDERSTANDING BEHAVIORAL INTENTION OF E-LEARNING SYSTEM RE-USE

Authors:

Yan Li and Yanqing Duan

Abstract: With the rapid development of information and communication technologies, e-learning system has emerged as a new means of education. The learner acceptance of e-learning system has attracted extensive attention, but how the experience of using the existing e-learning system impacts on their behavioural intent to the e-learning system re-use has received limited consideration. As the application of e-learning is gaining its momentum, it is necessary to examine the relationships of e-learners’ experience and their behavioural intention of re-use. It was argued that the better understanding of the factors affecting the e-learner’s behavioural intention in the future could help e-learning system researchers and providers to develop more effective and acceptable e-learning systems. Based on the technology acceptance model, information system success model and self-efficacy theory, a theoretical framework was developed to investigate the learner’s behavioural intention to e-learning system re- use. A total of 280 university students were surveyed to test the proposed structural model. The results demonstrated that perceived usefulness, perceived ease of use, service quality, course quality and self-efficacy had direct effects on users’ intention to re-use. Furthermore, self-efficacy affected perceived ease of use which positively influenced perceived usefulness.

COMPUTER AIDED SYSTEM FOR MANAGING DOMAIN KNOWLEDGE - Application to Cultural Patrimony

Authors:

Stefan du Château

Abstract: This paper presents our hybrid system for cultural heritage management. It combines the techniques of signal and natural language processing and knowledge modelling to effectively help a researcher in cultural patrimony in collecting, recording and finding the relevant knowledge. The voice interface serves to describe the artefacts in a given historical place. This audio file is than “translated” into a text file and validated by an expert in the area. The next step is an automatic concept extraction and building specific ontologies for the future processing. After introducing the problem of on field information collecting and managing, we describe the specific work of a researcher in the field of cultural heritage and main difficulties. Furthermore we explain our choice of the architecture of this hybrid system, our experiments and the results. Finally we give some perspective on extending this system to the other domains.

WORKAWARE - Situation-aware Workflow Management

Authors:

Wolfgang Gottesheim, Stefan Mitsch and Werner Retschitzegger

Abstract: Business processes face constantly changing context factors like varying customer behavior or market conditions that force to adapt the underlying workflows to these evolving situations. Information overload induced by the diversity of context factors, however, leads to the inability to provide coherently modeled, comprehensible, and re-usable workflows, the failure to recognize relevant situations in time, and finally, the lack of provenance information urgently needed for optimizing workflows. The main goal of our research project WorkAware is to leverage situation awareness in all phases of business process management. WorkAware will be based on a generic ontology-driven framework for situation perception, comprehension and projection and will employ aspect-oriented techniques for achieving extensible workflow models and tracking of provenance information.

A FRAMEWORK TO MEASURE THE IMPACT OF KNOWLEDGE PROCESS SUPPORTING TECHNOLOGIES - An Integrated Approach for a Technology-oriented Business Benefit Analysis

Authors:

Marcel Scheibmayer

Abstract: Within the last decade a plethora of different technologies emerged claiming to support knowledge worker in their everyday working life. Based on these technologies many different solutions for knowledge process support in enterprise environments have been developed. However the impact of these solutions is mostly considered intangible due to the fact that the overall costs and benefits are not clearly traceable. Traditional approaches for the evaluation of the costs and benefits often cover only a part of the overall scope, leading to an imminent need for a fitting assessment methodology. This paper presents a research approach to develop an integrated cost-benefit-framework, which integrates traditional aspects and related methodologies with emerging, knowledge process based aspects.

THE VALIDATION OF A DYNAMIC SERVICE COMPOSITION MODEL USING A SIMPLE GAME

Authors:

Abhishek Srivastava and Paul G. Sorenson

Abstract: Service composition is fast becoming a dynamic process where the selection of service elements and their subsequent composition happen at run time. A number of models have been proposed that support dynamic composition. The big issue lies in the validation of such models. A straightforward method of validating such models is to put together a service composition comprising of actual service elements and testing the efficacy of the application. However, this is not always feasible because of the expenses involved in such an experiment combined with the legal and privacy issues with the service providers. In this paper, we propose a novel idea wherein the validation of a dynamic service composition model can be done using a simple ‘Ambitious Traveler’ game. The game comprises the selection from a set of predefined transportation services using a dynamic composition model and separately by a group of volunteers who serve as customers. The selections of the two are compared and whosoever makes a better selection gets a higher score. The game is simple and may be modified to validate dynamic systems of other kinds as well. The specific approach and game described in this paper is currently under development.

CLOUD ARCHITECTURE FOR E-COLLABORATION IN THE INTERMODAL FREIGHT BUSINESS

Authors:

Bill Karakostas and Takis Katsoulakos

Abstract: The term freight refers to goods transported using different transport modes (truck, rail, ship), while inter-modality refers to the ability for seamless transfer of freight and information across the different transport modes. Because of the nature of the freight business (large number of small players, geographical distribution, complex regulatory regime, multiple standards, and IT heterogeneity) we propose that cloud computing presents an ideal platform for e-collaboration in the inter-modal transport networks (e-freight). This paper identifies Cloud based collaboration scenarios in e-freight, proposes a Cloud architecture for e-freight and analyses its business and technical benefits.

AUTHORIZATION IN CLOUD E-RADIOLOGY SERVICES

Authors:

Vassiliki Koufi

Abstract: The confidentiality of healthcare information is extremely important in any healthcare system. This paper is concerned with the development of suitable authorization and access control framework for eRadiology seen as a cloud computing service offered to healthcare professionals and patients alike. While eRadiology is expected to improve many aspects of healthcare, these high expectations will be achieved only if provider organizations pay continuing attention to the features that would most improve patients’ safety and health and select systems that have such appropriate features, security being among the most prominent ones. In particular, although the eRadiology workflow varies with the context, giving rise to specific ordering of task executions, it is authorization that determines who can execute the various workflow tasks and what information can be accessed during task executions. The main objective of this paper is to embed context-aware access control into eRadiology workflows, operating in conjunction with a personal healthcare record (PHR) system which has been implemented in a cloud computing infrastructure. The proposed model enables authorization to be based not only on static rules and roles but also to be influenced by the workflow execution context ensuring precise and tight access control. The resultant security system has been incorporated into a prototype eRadiology workflow to enable authorized access to patient information when and where needed.

KNOWLEDGE DIFFUSION

Authors:

Mounir Kehal

Abstract: Knowledge diffusion may be considered as “the adaptation of knowledge in a broad range of scientific and engineering research and development… The growth of scientific knowledge is largely due to a diffusion process in which new ideas are transmitted from person to person ”. Chen et al (2004). We have conducted studies on scientific and commercial documents, in other words traces of knowledge within a research and development institution and its commercial / spin-off counterpart. Observational and systematic (corpus-based) studies – through analysis of specialist text, can support research in knowledge management. Since text could be assumed to portray a trace of knowledge. In this paper we are to show how knowledge diffuses in a specific environment, and thus could be modeled by specialist text. That is dealing with the satellite manufacturing domain, and having embedded within the knowledge about the business sector and knowledge domain.

A NEW FRAMEWORK FOR THE CONTROL OF LMS IN ITS

Authors:

Veronica Amela

Abstract: Intelligent Tutoring Systems (ITS) offer an automatically personalized environment guiding the student and allows him to put his knowledge and skills in a more effective way than with traditional lessons. Besides, this learning methodology gives study location and time freedom to the student thanks to Internet facilities. Moreover the Learning Management System (LMS) or plat-form which holds the ITS, gathers the course materials and student information making them available and reusable for other control courses. In this paper, we propose a new approach to LMS in ITS, applying data mining techniques.

EFFECTIVENESS OF SOCIAL NETWORKING IN A UNIVERSITY LIBRARY ENVIRONMENT

Authors:

Hou Ieong Ho and Jieh Hsiang

Abstract: As social networking becoming commonplace among the young patrons of the libraries, many libraries are incorporating their services into existing social networking environments. However, there have not been many studies on the effectiveness of such services. In this paper, we describe how the National University Library utilizes two social networking platforms, Facebook and Plurk, to provide better services to its webized community. The effectiveness of these services is demonstrated through a quantitative analysis. Different behaviour due to the different propagation mechanisms of Facebook and Plurk is also discussed. Our results indicate that certain library services using social networking services are easy to build, easy to maintain, easy to analyze, and are effective for reaching out to webized patrons.

Authors:

Błażej Zyglarski and Piotr Bała

Abstract: In this paper we show our approach to keywords extraction by natural language processing. We present revised and extended version of previously shown document analysis method, based on Khonen Neural Networks with Reinforcement, which uses data from the large document repository to check and improve results. We describe new improvements, which we’ve achieved with preprocessing set of words and creating initial ranking using Markov Chains. Our method shows, that keywords can be selected from the text with great accuracy. In this paper we present evaluation and comparison of both methods and example results of keywords selection upon random documents.

TOWARDS A PROCESS OF BUILDING SEMANTIC MULTIMODAL DIALOGUE DEMONSTRATORS

Authors:

Daniel Sonntag and Norbert Reithinger

Abstract: A generic integration framework should allow us to build practical dialogue systems for specific use case scenarios. While domain-specific dialogue systems are simpler to achieve than more general, open-domain conversational dialogue systems, the integration into use cases and demonstration scenarios requires a lot of difficult integration work, especially in multimodal settings where different user devices such as touchscreens and PDAs are used. The challenges for those systems include, apart from the dialogue modelling task, the integration modelling for specific use case and demonstration scenarios. This paper reports on dialogue system prototype development based on ontology communication structures and we draw special attention to the process of how to build demonstration systems that include a task-oriented, information-seeking, or advicegiving dialogue as an important fragment of practical dialogue system development.

A NEW KNOWLEDGE MANAGEMENT TOOL TO FACILITATE PROCESS INNOVATION IN MANUFACTURING COMPANIES

Authors:

Daniela Butan, Emma O'Brien and Mark Southern

Abstract: This paper presents a novel KM tool to allow companies to obtain sufficient knowledge about its process in order to enhance its competitiveness and to innovate. To date there is no practical multidisciplinary model that enables companies to switch from engineering chaos to a structured, robust process. This new approach creates a reliable framework which promotes innovation and it offers a sustainable model for knowledge creation in that the knowledge generated through its use can be continuously build upon to expand the body of internal knowledge within the company. The model is based on existing engineering tools and exploiting the knowledge generated through their use using the interchange between tacit and explicit knowledge thus it is presented in the context of Nonka’s knowledge spiral. The model has been used successfully in a number of case studies one which is presented in this paper.

KNOWLEDGE VALIDATION IN SMES

Authors:

A. I. Bani-Hani

Abstract: Knowledge Validation is a challenge in Small to Medium Sized Enterprises, SMEs, as most of the available information is held in peoples minds as tacit knowledge, or saved on each employees PC without sharing or common validation. This case study is based on a company in Leicester after installing an enterprise resource planning (ERP) system. The underlying reasons for these problems were due to the distributed and tacitly held knowledge where the assumptions in one part of the company were inconsistent with other parts. The paper analyses the main problem of validating knowledge in more detail and has identified the consequences of failing to do this. Challenges are discussed and highlighted in the paper, which concludes at the end the importance of Knowledge Validation and identifies some solutions.

A FRAMEWORK TO SUPPORT KNOWLEDGE TRANSFER IN THE SERVICE SECTOR

Authors:

Simrn Kaur Gill

Abstract: This paper introduces a framework for analysing and supporting knowledge transfer in healthcare services. It argues that the individual is at the centre of the transfer process and, as such, needs to be catered-to within both teams and organisations. Within the healthcare sector, safety is critical, and the effective and efficient transfer of knowledge between healthcare professionals and patients can help to reduce the risks in the system. Furthermore, the authors hope that a clear understanding and accurate identification of the factors that impact the knowledge transfer process for individuals can have an impact on the knowledge transfer process in teams and organisations. The development of a suitable approach to support knowledge transfer for improved transfer of knowledge among these groups in the healthcare services is achieved using technology where appropriate, through the knowledge transfer framework which is presented.

A KNOWLEDGE-CENTRIC E-RESEARCH PLATFORM FOR MARINE LIFE AND OCEANOGRAPHIC RESEARCH

Authors:

Ali Daniyal, Samina Abidi and Ashraf AbuSharekh

Abstract: In this paper we present a knowledge centric e-Research platform to support collaboration between two diverse scientific communities—i.e. Oceanography and Marine Life domains. The Platform for Ocean Knowledge Management (POKM) offers a services oriented framework to facilitate the sharing, discovery and visualization of multi-modal data and scientific models. To establish interoperability between two diverse domain, we have developed a common OWL-based domain ontology that captures and interrelates concepts from the two different domain. POKM also provide semantic descriptions of the functionalities of a range of e-research oriented web services through a OWL-S service ontology that supports dynamic discovery and invocation of services. POKM has been deployed as a web-based prototype system that is capable of fetching, sharing and visualizing marine animal detection and oceanographic data from multiple global data sources.

SOLVE INSUFFICIENT COMMUNICATIONS - A Measurement-method for Satisfied Communication in Business Organizations

Authors:

Eldar Sultanow

Abstract: Communication in widely distributed organizations is in many cases unsatisfactory. This contribution presents a method, which enables scalability for satisfied communication in business organizations. This method has been applied in practice and further evaluated by two IT-companies, which operate globally in the field of Web Engineering, E-Commerce and Usability. In the course of the evaluation for a one-month period, personnel were introduced to a checklist, which is specially designed for capturing communication dissatisfaction. The findings within these two companies are alarming in several respects. Many communication channels, which personnel choose by default, are inadequate and thus unacceptable for them and for the respective communication partners.

TAKING PRESSURE OFF KNOWLEDGE WORKERS WITH THE HELP OF SITUATIONAL APPLICATIONS - Improving Time-to-proficiency in Knowledge Work Settings

Authors:

Daniel Bachlechner and Michael Kohlegger

Abstract: Knowledge work is weakly structured, highly diverse and fast changing and thus needs flexible, personalised support by software. Situational applications are a new breed of software that is assumed to fit to the types of tasks and contextual requirements encountered in knowledge work settings. Furthermore, their application is supposed to result in shorter time-to-proficiency. The main goal of this paper is to discuss these assumptions taking the constructs of the task-technology fit model as well as the relationships among them into account. Based on the model, three propositions are developed and discussed.

UNIVERSAL EXTRA-FUNCTIONAL PROPERTIES REPOSITORY - Model Overview and Implementation

Authors:

Kamil Ježek

Abstract: The current Internet is still more used for accessing data through remotely invoked services. Although it allows rapid development of new systems, it still has some limitations. This paper addresses extra-functional properties that must be taken into account to develop systems concerning calls of remote services. Since the services provide general functionality among worldwide applications, their extra-functional properties must be also generally accessible. Hence this paper targets less explored area of exchanging extra-functional properties via the Internet. For that reason we propose a model as well as an implementation of a universal repository that stores and accesses extra-functional properties. Main contribution of such repository is that the services use common extra-functional properties from one repository and thus different vendors work with the same and compatible properties.
