Compounds and distributional thesauri

The building of distributional thesauri from corpora is a problem that was the focus of a significant number of articles, starting with (Grefenstette, 1994) and followed by (Lin, 1998), (Curran and Moens, 2002) or (Heylen and Peirsman, 2007). However, in all these cases, only single terms were considered. More recently, the topic of compositionality in the framework of distributional semantic r...

Aligning Multilingual Thesauri

The aligning and merging of ontologies with overlapping information are actual one of the most active domain of investigation in the Semantic Web community. Multilingual lexical ontologies thesauri are fundamental knowledge sources for most NLP projects addressing multilinguality. The alignment of multilingual lexical knowledge sources has various applications ranging from knowledge acquisition...

Evaluating Roget's Thesauri

Roget’s Thesaurus has gone through many revisions since it was first published 150 years ago. But how do these revisions affect Roget’s usefulness for NLP? We examine the differences in content between the 1911 and 1987 versions of Roget’s, and we test both versions with each other and WordNet on problems such as synonym identification and word relatedness. We also present a novel method for me...

Machine Translation of Bio-Thesauri

In this paper we describe how we applied a generalpurpose machine translation tool for translating biomedical thesauri. We used corresponding terms in parallel corpora to check the validity of the translations. The advantage of this approach is that a single corresponding set of terms can be verified where techniques to retrieve translations from a parallel corpus do not exploit the knowledge c...
