The exciting Topic Maps (TMs) are an ideal catalyst for mutual learning experiences for proponents from the partially overlapping communities of Knowledge Organization (KO), Knowledge Management (KM) and Information Technology (IT). A long-term goal would be a tutorial white paper on the relationship between KO, KM and TMs, together with free reference software. KO is interested in optimizing the organization (the conceptual access structure) of knowledge repositories to support easier retrieval, creation and sharing of knowledge for user communities. TMs can indeed play an important role within KO: Together with related technologies, they have made it easier to provide innovative KO services. With TMs you can define arbitrarily complex knowledge structures and attribute them as metadata to information resources. Decentrally creating, maintaining and exchanging even more heterogeneous metadata is a powerful basic service of high interest for a broad range of applications. However, sooner or later you have to cope with the new semantic heterogeneity and come up with strategies to achieve better semantic interoperability. How could TM-based services alleviate the pressing KO problem of how to reorganize, enhance and semantically integrate heterogeneous subject data? Dedicated to this question, this talk takes a KO perspective: By sketching three typical scenarios in which heterogeneous metadata occur, it shows how classical KO challenges reappear with TMs, but also that TMs may be of value. Because the authors of the TM standard were right in not prescribing the application semantics of the structured link network, the widespread use of large-scale TMs will aggravate the well-known problem of the comparability and compatibility of KO schemata. A closer co-operation between the communities could aid the potential of TMs for KO/KM. Fortunately, the TM community has already started the fruitful exchange by discussing KO-relevant topics. Because of the flexible orientation of TMs towards usage contexts, especially user-oriented indexing should benefit from TMs. Approaches for achieving semantic interoperability within a layered model of decentral information provision are briefly presented as background against which further directions of KO with TMs can be discussed. One consequence for KO is that its methodology must be partially redesigned to take collaborative knowledge building activities on distributed resources more into consideration. This article also asks about the relationship between TMs and other means to computationally handle semantics in next-generation ontology- and agent-based knowledge services. In the end, possible further research towards this vision is suggested. (AU) |

An important aspect of knowledge management is the implementation of methods to share the idiosyncratic knowledge of expert practitioners within an organization. In order to make such knowledge sharable, it is necessary to have both an effective elicitation method and a useful representation scheme. In this paper we describe the PreSERVe method of knowledge elicitation as it is used with a knowledge representation scheme based upon concept maps [1]. We describe the use of these methods in a case study on the capture and representation of local weather forecasting knowledge. (AU) |

This study examined the use of concept maps for Web-based applications in higher education. The purpose of the project was to design concept maps that could serve as prototypes for navigating and searching Internet resources. It also explored the value of concept mapping as a method of bibliographic retrieval for the ERIC database. Following an extensive literature review, the study compared competing methodologies for developing concept maps; analyzed primary ideas about concept maps; described procedures for developing maps; discussed assumptions about what makes good concept maps for facilitating Internet and print navigation; identified and tested software for developing concept maps; and examined navigation issues for utilizing concept maps. Results suggest concept maps are becoming more widespread in their application to various purposes; software packages have changed
significantly since the advent of the Web but none of the software evaluated offered all the necessary features. While concept maps may be quickly created, the resulting maps may not adequately map the knowledge base. Concept maps have much to offer the ERIC system, and a hybrid mix of existing, inexpensive tools may be useful to leverage technology and provide a new user interface. An annotated bibliography is included. (Contains 24 references.) (AU)

Topic maps are a new ISO standard for describing knowledge structures and associating them with information resources. As such they constitute an enabling technology for knowledge management. Dubbed "the GPS of the information universe", topic maps are also destined to provide powerful new ways of navigating large and interconnected corporaWhile it is possible to represent immensely complex structures using topic maps, the basic concepts of the model - Topics, Associations, and Occurrences (TAO) - are easily grasped. This paper provides a non-technical introduction to these and other concepts (the IFS and BUTS of topic maps), relating them to things that are familiar to all of us from the realms of publishing and information management, and attempting to convey some idea of the uses to which topic maps will be put in the future.
