K-CAP 2005 Workshop on:

Ontology Management:

Searching, Selection, Ranking, and Segmentation

Sunday, October 2, 2005 at Banff, Canada

Ontologies are a cornerstone of the Semantic Web, and are probably the most important form of knowledge representation currently used in both Artificial Intelligence and on the Semantic Web. Building the required ontologies represents a major challenge both because of the complexity of each knowledge domain and because of the sheer number of ontologies the Semantic Web will require. It takes a considerable amount of time and effort to construct a single ontology, and even more if the engineer lacks first hand knowledge of the domain they are trying to represent. However, one of the original motivations and supposed advantages of ontologies is that they facilitate “knowledge reuse”. In theory, existing ontologies constructed by third parties could be reused, modified, extended and pruned as required, thereby avoiding the considerable effort of starting from scratch. To achieve this level of reuse, however, an appropriate infrastructure of tools and methods must be made available to allow the search, selection and general management of the existing resources.

Ontology search systems permit the identification from the plethora of web resources of only those items which are proper ontologies. Ontology ranking involves the ranking of the retrieved entities in accordance with a number of criteria, including the presence and absence of certain terms, and their position in the ontology. Ontology segmentation involves the ability to select and extract a particular sub-section of an existing ontology for the current needs. In order to facilitate these procedures, ontology visualisation and editing are necessary.

This workshop will encourage the presentation and exploration of solutions to key aspects of ontology management and it is expected to stimulate further research in these important issues. This workshop intends to bring together researchers and practitioners from a wide area of research, such as semantic web, knowledge management, information retrieval, to discuss the issues above and exchange knowledge and experience.

Topics of Interest

Potential Audience

This workshop intends to bring together researchers and practitioners from a wide area of research, including the semantic web, knowledge management, information retrieval, in order to discuss the issues and exchange knowledge and experience. More specifically, the workshop is expected to attract researchers and practitioners interested in ontology building, usage, brokering, searching, and maintenance.

Submission

We welcome the submission of full papers (up to 8 pages) describing some ongoing work relevant to this workshop’s topics of interest, and short papers (up to 4 pages) for position statements and new ideas. Papers must be formatted using the K-CAP 2005 formatting guidelines on the conference website. Please email your submissions in PDF to , no later than 11:59pm 25th July 2005.

Full papers will be given a 30 minutes slots, where one of the authors will be expected to present the paper in a maximum of 20 minutes, leaving at least 10 minutes for questions. Each short paper will be allowed a 10 minutes presentation, followed by 5 minutes questions time. Each submitted paper will be reviewed by two nominated reviewers to assess its research merit and suitability for this workshop. The last session of the workshop will be reserved for discussions only to allow the attendees and organisers to reflect on the talks and discussions that took place during the workshop.
