| Abstract(in English) | In the natural language processing by computer it is one of the problems that there are lots of syntactic structures corresponding to the input sentence. If syntactic structures can be chosen correctly in a view of meanings, the quality of processing will be more improved. Up to now, Selectional Restriction has been used conventionally. But, the semantic category used by this restriction was very rough and not precise. Besides it was uncertain how much it satisfied probability of the syntactic structure and the dependency constraint. In this report, we propose Context Free Grammers expressing the dependency constraint by production rules. In these grammars nonterminal symbols are subdivided based on what are expressed by phrases derivated from nonterminal symbols, and superordinate-subordinate relations are treated as production rules. |
