In general, the work is a good example of: 1. the necessity of creating extensive lexicons, where "extensive" must be intended both in breadth (i.e., in quantitative terms) and in depth (i.e., from aqualitative viewpoint, as to the types of information associated with the entries); 2. the necessity of working with large textual corpora, both for obtaining linguistic data and for testing systems. This is encouraging for a trend that is in recent years showing up, and having, for example, in Europe, great success also in projects sponsored by national and international organizations.
