We build upon a previously implemented platform that extracts a semantic network and taxonomy from the English version of theWikipedia. We describe two accomplishments of our work: the semantic network for the German language in which isa links are identied and annotated, and an expansion of the platform for easy adaptation for a new language. We identify the platform's strengths and shortcomings, which stem from the scarcity of free processing resources for languages other than English. We show that the taxonomy induction process is highly reliable ñ evaluated against the German version of WordNet, GermaNet, the resource obtained shows an accuracy of 83.34%.Tue Mar 03 19:19:27 CET 2009Berlin, HeidelbergProceedings of the 5th European Semantic Web ConferenceJuneLNCSDistinguishing between Instances and Classes in the Wikipedia Taxonomy2008Instances Taxonomy Wikipedia classes distinguishing instances taxonomy This paper presents an automatic method for differentiating between instances and classes in a large scale taxonomy induced from the Wikipedia category network. The method exploits characteristics of the category names and the structure of the network. The approach we present is the first attempt to make this distinction automatically in a large scale resource. In contrast, WordNet and Cyc rely on manual annotations. The result of the process is evaluated against ResearchCyc. On the subnetwork shared by our taxonomy and ResearchCyc we report 84.52% accuracy.
