“…Secondly experience showed that the lexical ambiguity carried by generic dictionaries does not allow their direct use in computational systems (Basili and Pazienza, 1997;Morgan et al, 1995). Even when they are used off-line, lexical ambiguity can introduce so much noise (and then overhead) in the lexical development process that their use can be inconvenient from the point of view of efficiency and effectiveness.…”

Lexicon definition is one of the main bottlenecks in the development of new applications in the field of Information Extraction from text. Generic resources (e.g., lexical databases) are promising for reducing the cost of specific lexica definition, but they introduce lexical ambiguity. This paper proposes a methodology for building application-specific lexica by using WordNet. Lexical ambiguity is kept under control by marking synsets in WordNet with field labels taken from the Dewey Decimal Classification.
