Abstract
A method and apparatus for machine translation of language is disclosed. For each translation pattern, qualified words and corresponding translations are extracted. The invention generalizes words by converting them into concepts which are more general and can be applied to many inputs. A partial thesaurus is generated that describes hierarchies of words and concepts that are hypernyms of these words. Based on frequency information obtained for the words, an importance value is computed for each concept. Importances are used to determine the possibility of generalizing concepts in the translation.
