Kommunikative Erzeugung, Darstellung und Anwendungen Offener Ontologien und Offener Wissensbasen
Zusammenfassung der Projektergebnisse
The research project "Communicative Acquisition, Representation and Evolution of Open Ontologies and Open Knowledge Bases" (Open Ontologies and Open Knowledge Bases for short) focused on foundational and formal approaches to the acquisition, evolution, representation and integration of communicatively (i.e., socially) generated semantically heterogeneous knowledge in open information environments like Social Software (such as Weblogs and social networking sites), the Semantic Web, Enterprise Knowledge Managementsystems, MultiagentSystems, and Peer2Peer networks. In contrast to traditional approaches to knowledge and ontology acquisition, integration and sharing, which emphasize homogeneity and consensus finding, the formal and technical framework developed in this project allows for the co-existence, probabilistic weighting, comparison and evolution of heterogeneous individual and social viewpoints (for example, conflicting opinions) on the semantic level and in multiple levels of complexity reduction while integrating and aggregating. Formal means developed for the formal representation of Open Ontologies and Open Knowledge Bases allow to incorporate meta-knowledge about social contexts of knowledge generation and usage, and knowledge and ontologies derived from communication processes, whereby both direct/synchronous communication and implicit/asynchronous communication (e.g., semantic interrelations of different web sites) are supported.
