Semi-automatic compound nouns annotation for data integration systems

Lexical annotation is the explicit inclusion of the \u201cmeaning" of a data source element according to a lexical resource. Accuracy of semi-automatic lexical annotator tools is poor on real-world schemata due to the abundance of non-dictionary compound nouns. It follows that a large set of relationships among different schemata is discovered, including a great amount of false positive relationships. In this paper we propose a new method for the annotation of non- dictionary compound nouns, which draws its inspiration from works in the natural languagedisambiguation area. The method extends the lexical annotation module of the MOMIS data integration system
