DOGMA ontology research (Developing Ontology-Grounded Methods and Applications)

DOGMA stands for Developing Ontology-Grounded Methods and Applications. In this project (partially supported by the V.U.B. internal research fund) we are setting up a set of ontology servers in order to assist the community-based gathering and incremental evolution of ontologies. The separation of an ontology into lexons (extremely simple linguistic structures) and a layer of ontological commitments (reified as annotated constraints of lexon usage by applications) intends to achieve a degree of scalability not possible with more complex representations hitherto used in the semantic web literature and practice. This extensional approach naturally leads to very large sets, thereby moving the research issue to fundamental principles of the processes and methodology surrounding ontology engineering such as community agreement, evolution and organization, rather than 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.
