1. A method for automatically disambiguating the synonymic links in a dictionary for a natural language processing system, wherein said dictionary is stored in the memory of a data processing system and includes a list of "meaning-entries" with their respective synonym lists, characterized in that it comprises the following steps:

  • reading from said dictionary a "meaning-entry", the words from which it is a synonym and its own synonyms, to build a synonymic environment table;

    digitizing said environment table to build an environment matrix;

    building a similarity matrix by computation of similarity indexes between the elements of said environment matrix;

    incrementally clustering the words having the greatest similarity index, first with said "meaning-entry" and thereafter with the previous clusters; and

    writing the "meaning-entry" and the obtained cluster containing the disambiguated synonyms back into said dictionary.
