The importance of cross-lingual information for matching Wikipedia with the Cyc ontology

In this paper we try to answer the question how cross-lingual evidence may improve matching between different classification schemas. We concentrate specifcally on the task of mapping between Wikipedia categories and Cycterms as well as the classication of Wikipedia articles to the Cyctaxonomy and show how this process may be improved by consuming the evidence that is available in different editions of Wikipedia. The results show that the performance of the mapping procedure may be improved from 0.6 to 4.9 percentage points, depending on the number of external Wikipedia editions and the given task.
