Abstract

The focus of data integration systems is on producing a comprehensive global schema successfully integrating data from heterogeneous data sources (heterogeneous in format and in structure). Starting from the “meanings” associated to schema elements (i.e. class/attribute labels) and exploiting the structural knowledge of sources, it is possible to discover relationships among the elements of different schemata. Lexical annotation is the explicit inclusion of the “meaning” of a data source element according to a lexical resource. Accuracy of semi-automatic lexical annotatortools 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 ofnon-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.
