OntoLT Version 1.0: Middleware for Ontology Extraction from Text

In: Proc. of the Demo Session at the International Semantic Web Conference. International Semantic Web Conference (ISWC), 2004.


We describe OntoLT, a plug-in for Protégé1 with which concepts (Protégé classes) and relations (Protégé slots) can be extracted automatically from linguistically annotated text collections. OntoLT provides mapping rules, defined by use of a precondition language that allow for a mapping between linguistic entities in text and class/slot candidates in Protégé.
