- KonferenzbeitragEvolution of the metadata in the ontology-based knowledge management systems(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Stojanovic, Ljiljana; Stojanovic, Nenad; Handschuh, SiegfriedAn ontology-based knowledge management system uses an ontology to represent explicit specification of a business domain and to serve as a backbone for providing and searching for knowledge sources. But, dynamically changing business environment implies changes in the conceptualisation of a business domain that are reflected on the underlying domain ontologies. Consequently, these changes have effects on the performances and validity of the KM system. In this paper we present an approach for enabling consistency of the description of knowledge sources in an ontology-based KM system in the case of changes in the domain ontology. This approach is based on our research in the ontology evolution and ontology-based annotation of documents. The proposed method is implemented in our semantic annotation framework so that effcient acquiring and maintaining of ontology-based metadata is supported.
- KonferenzbeitragArchitecture-based integration of CBR-components into KM-systems(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Gronau, Norbert; Laskowski, FrankKnowledge-Management (KM)-systems integrate multiple technologies with the purpose of supporting users who have "knowledge-related" problems. Case-Based Reasoning (CBR)-technology is well known for improving problem solutions. Combining both concepts the project "TO-KNOW" has the goal to design a CBR-component that is adaptable to typical KM-Systems. The basic idea is to take into account user-queries as (intermediate) problem-solutions for getting the needed information from the KM-System's discovery services. In this paper we describe an architecture-based approach to design the CBR-component yielding a light-weighted integration into a KM-system. This is accomplished by looking at both parts designated for integration in terms of their architecture, i.e. the modularity of data and functionality. Since different KM-systems will allow various degrees of synergy, the process should result in a highly modularized CBR-component being ready for different models of integration. An overview about our design-method is given as well as examples covering first results on a more detailed level.
- KonferenzbeitragTowards the fast monitoring of case properties(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Iglezakis, IoannisApplying case properties over a case base can indicate conflicts in or between cases. Monitor these results is important to trigger the maintenance of a case-based reasoning system. However, the complexity of applying a single case property over a case base is O(n2).
- Konferenzbeitragempolis orenge – an open platform for knowledge management applications(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Schumacher, Jürgenempolis orenge 4.0, acomponent-based environment for knowledge management applications by empolis Knowledge Management, is a flexible and scalable Case-Based Reasoning shell for industrial applications, that also contains many components that provide functionality beyond the basic CBR paradigm. Further it can be extended easily by application-specific components, which makes it an ideal starting point for experimental CBR-oriented research projects, too.
- KonferenzbeitragConstruction of BDI agents from CBR systems(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Corchado, J. M.; Laza, R.This paper shows how deliberative agents can be built by means of a case-based reasoning system. The concept of deliberative agent is introduced and the case-based reasoning model is presented. Once the advantages and disadvantages of such agents have been discussed, it will be shown to solve some of their inconvenients, especially those related to their implementation and adaption. The World WIde Web has emerged as one of the most popular vehicle for disseminating and sharing information through computer networks, a distributed agent-based solution for e-business, in which such agents have been used, is also presented and evaluated in this paper.
- KonferenzbeitragPrognostic model for early warning of threatening influenza waves(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Schmidt, Rainer; Gierl, LotharThe goal of the TeCoMed project is to send early warnings against forthcoming waves or even epidemics of infectious diseases, especially of influenza to interested practitioners, pharmacists etc. in the German federal state of Mecklenburg-Western Pomerania. The forecast of these waves is based on written confirmations of unfitness for work of the main German health insurance company. Since influenza waves are difficult to predict because of their cyclic but no regular behaviour, statistical methods based on the computation of mean values are not helpful. Instead, we have developed a prognostic model that makes use of similar former courses. Our method combines Case-based Reasoning with Temporal Abstraction to decide wether early warning is appropriate. In this paper, we present this method.
- KonferenzbeitragA knowledge sharing model for peer collaboration in the non-life insurance domain(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Dignum, VirginiaIn this report we describe KennisNet, a community support system developed at Achmea, where developers of non-life insurance products collaboratively construct and share a repository of knowledge items. The aims of KennisNet are to structure, initiate and organise the sharing of knowledge within the group. The KennisNet framework assures the continuous availability of consistent and up to date information and knowledge. The components of the system are face-to-face workshops and a knowledge sharing server. The model draws on different technologies and methods such as knowledge modelling and representation, user-centred design, intelligent agents and visualisation.
- KonferenzbeitragIntelligent human computer collaboration (HCC)(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Funk, PeterClaims have been made that more than 50% of companies corporate knowledge is inside peoples heads. Sharing experience and knowledge in companies is largely unsupported. Networks of people have proven to be efficient both within organisations and within groups of people sharing the same profession etc. We propose an approach where experience and knowledge is shared in a dynamic collaboration between humans and computers where the issue is to efficiently capture/share/reuse experience and knowledge. For this we propose the use of a number of different methods and techniques, in particular EM and AI methods and techniques, CBR, collaborative filtering, user modelling...
- KonferenzbeitragThe architecture and business model of the Fraunhofer FIRST/IGD knowledge management portal(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Melster, Ronald; Storl, ChristianThis paper describes a web-based knowledge management system for editing and visualising facts in a new innovative way. The foundation of the portal is a commercial framework for building information systems. Furthermore, the XTM topic map standard is used for representing the facts and their relationship in the system. In this paper, the overall architecture of the framework and the features we used are described. In the next chapter the representation and modelling of the XTM topic map standard is depicted in detail. In the last chapter the new three-dimensional user-interface is shortly illustrated.
- KonferenzbeitragContext driven spontaneous knowledge exchange(1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Schwotzer, ThomasThe way we work is changing fundamentally. Broadly available mobile networks give us the technical opportunity to be more flexible in time and space. The better understanding of learning organizations leads to a reorganization of business processes. There is also a trend to make the Internet more "intelligent". This paper discusses how contexts can be used to manage the exchange of knowledge in mobile spontaneous networks. We motivate and introduce a new concept called knowledge port, which is an extension of Topic Maps and Semantic Web. This approach seamlessly integrates normadic employees in the knowledge management policy of their company. It can also be used to offer location based knowledge.
