Karl Hammar är chef för Avdelningen för Datavetenskap och forskare inom Jönköping AI Lab (JAIL).

Forskning

Dr Hammars forskningsfokus ligger på att utveckla och utvärdera metoder för standardiserad datarepresentation och dataintegration mellan heterogena underliggande system; i huvudsak med hjälp av semantiska teknologier som OWL-ontologier och RDF-baserade kunskapsgrafer. Hans största bidrag har varit utvecklingen av förenklade metoder för ontologimodellering (med hjälp av designmönster) samt utvecklingen av den i fastighetsbranschen väletablerade RealEstateCore-ontologin för smarta byggnader.

Biografi

Karl har en teknologie doktorsexamen i datalogi från Linköpings Universitet. Han har varit aktiv i ett flertal nationella och internationella forskningsprojekt rörande kunskapsrepresentation och den semantiska webben, med tillämpningsområden som inkluderar säkerhet och övervakning, veterinär epidemiologi, mjukvarutestning, brottsbekämpning, etc. Han har presenterat sin forskning vid ledande internationella konferenser, såsom ISWC, ESWC, EKAW, BIR, etc., och har arrangerat workshops och seminarier såväl för akademi som näringsliv.
