D3.2.2 Usage-driven Change Discovery: Evaluation

Bloehdorn, Stephan; Haase, Peter; Sure-Vetter, York

Abstract:
The world is constantly changing, and so does required and available knowledge, e.g. stored in Digital Libraries. Knowledge workers heavily rely on the availability and accessibility of knowledge contained in such libraries. The sheer mass of knowledge available today, however, requires sophisticated support for searching and, often considered as equally important, personalization.

In SEKT we address these challenges by using ontologies. Ontologies by nature make implicit knowledge explicit, they describe relevant parts of the world and make them machine understandable and processable. To be effective, ontologies need to change possibly as fast as the parts of the world they describe.

Change discovery aims at generating implicit requirements by inducing ontology changes from existing data. We here focus on {em usage-driven} change discovery. Usage data is a very valuable source of contextual information, based on which the ontology can be modified in order to reflect changes in the real world,

In a precedent deliverable we have presented a framework for usage-driven ontology evolution along with a set of methods for change discovery. ... mehr
