Welcome on my page, to the campus of UNB, including our NRC-IIT location, and in Fredericton. UNB and NRC Fredericton are strong players in Web-oriented Computer Science. I am leading the NRC SemWebLab, which conducts research in Semantic Web languages and applications, including rule-based knowledge representation. I am co-founder and co-chair of the RuleML Initiative as well as co-editor of the W3C Rule Interchange Format Working Group (RIF Wiki).

One of my current interests, in various teams, is Semantic Web knowledge representation joining rules and ontologies, as explored, e.g., with sorted Horn logics in Relfun, RuleML, and POSL, with the hybrid combination of Datalog and Description Logics from ALC to SHIQ in DatalogDL, as well as with the homogeneous integration of rules using default negation and ALC in ALCuP. Another current interest is the use of such Semantic Web knowledge representations for person/organization-centric profiles supporting FOAF-extending social networking and expert finding, as explored, e.g., with RuleML FOAF in FindXpRT and combined RDF vocabularies in the ExpertFinder initiative.

If you are interested to study in Fredericton, this is CS Information for Prospective Students.
If you are interested to work here, there may be a relevant IIT Job Posting for our Fredericton location, as e.g. in reasoning, semantic web, multi-agent systems, and SOA.

In particular, I am currently looking for students, knowledgeable in RIF-BLD or Derivation RuleML, working on their Schema specification (XML Schema for RIF-BLD / Schema Specification of RuleML) and on their Java Implementation.
