Background of DOGMA Ontology research
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. For more details click on one of the
