The Semantic Web, Databases and Ontologies
In the DOGMA project (funded for 5 years by the V.U.B. internal research fund) we are setting up an ontology server in order to assist the gathering and incremental growth of ontologies. The use of the extremely simple structures should -we conjecture- achieve at least a degree of scalability not possible with more complex representations hitherto used in the literature and practice. This extensional approach will naturally lead to very large sets, thereby moving the issue to matters of ontology organization, rather than of representational power or sophistication. Sources of domain-specific knowledge, as opposed to general-purpose lexicons like Wordnet etc., will be formed e.g. by relational database schemas, yielding an activity best described as ontology mining. Interesting research issues about contextual layers within ontologies arise here as one e.g. needs to separate local jargon from “common knowledge”. Other important sources are numerous existing thesauri and glossaries.
