ABSTRACT:
A method and system for automatically disambiguating the synonymic links in a dictionary for a natural language processing system. Said dictionary is stored in the memory of a data processing system and includes a list of headwords with their respective synonym lists. The same headword can have different meanings, each of which has its own synonym list, each of which also can have different meanings. Disambiguation of the synonymic links is performed by reading from said dictionary a "meaning-entry", the words from which it is a synonym and its own list of synonyms, to build a synonymic environment table. A similarity index is computed for each pair of words of said environment and the words having the greatest similarity with the aggregate are incrementally clustered. The final cluster is then validated and the "meaning-entry" and its disambiguated synonyms are written back into the dictionary.
