The system is based on a novel ontology learning framework which formalizes and extends the role of machine learning and text mining algorithms used in the previous version. List of new features includes extended number of supported ontology formats (RDFS and OWL), supervised methods for concept discovery (based on Active Learning), adding of new instances to ontology and improved user interface (based on comments from the users). %Z %U %+ %^ %0 %0 Conference Proceedings %A Brank, Janez; Grobelnik, Marko & Mladeni\'c,, Dunja %D 2005 %T A Survey of Ontology Evaluation Techniques %E %B Proc. of 8th Int. multi-conf.
