Abstract
CWSD (Combined Word Sense Disambiguation) is an algorithm for the automatic annotation of structured and semi-structured data sources. Instead of being targeted to textual data sources like most of the traditional WSD algorithms, CWSD can exploit knowledge from the structure of data sources together with the lexical knowledge associated with schema elements (terms in the following).
We integrated CWSD in the MOMIS system (Mediator EnvirOment forMultiple Information Sources) [1], which is an \({{\it I}^3}\) framework designed for the integration of data sources, where the lexical annotation of terms was performed manually by the user. CWSD combines a structural disambiguation algorithm, that starts the disambiguation process by using the semantic relationships extracted from the data source schemata and a WordNet Domains based disambiguation algorithm, which refines terms disambiguation by using domains information.
