Leif Harald Karlsen
Welcome to my personal website. I am a senior lecturer at University of Oslo at the Department for Informatics.
My interests are in databases, logic, spatial data and declarative programming.
I teach courses on databases, data modelling, data integration, semantic technologies and reasoning.
I currently teach the following two courses:
My main research interests lie in databases and knowledge representation, but I am also interested in functional and delcarative programming, as well as spatial and temporal data.
The main research project I am currently involved in is OTTR – Reasonable Ontology Templates.
For list of publications, see My page at UiO or my Google Scholar page.
The two programs Lore and TripleLore are extensions to SQL and allow Datalog-like rules (Lore) and RDF and ontologies (TripleLore) to be naturally represented in a relational database. These programs are used in the course IN5800.
