An Empirical Architecture for Verb Subcategorization Frame - a Lexicon for a Real-world Scale Japanese-English Interlingual MT
The verb subcategorization frame information plays a major role of disambiguations in many NLP applications. Japanese, however, imposes difficulties of subcategorizing in part because it allows arbitrary ellipses of case elements. We propose a new type of verb subcategorization frame code set that combines the verb's surface case set and the deep case set, as a solution to the difficulties of empirical researches on Japanese. The lexicon developed by this design has comprehensive information on the correspondences between the surface case frame and the deep case frame, and yet restrains the potential combinatorial explosion of the number of verb subcategorization frames by carefully identifying superficially different frames with an idea of alternative case markers and semantic roles, and by introducing the notion of surface case frame permutations. The number of different surface/ deep case mapping types is 250, after we completed the new subcategorization frame code development...
