Abstract(in English) | In this paper, we describe a semi-automatic learning method of the grammar rules for improving coverage of the sentences. It is possible to analyze the sentences that can not be accepted by preregistered production rules. When a sentence which is not accepted by production rules is inputted to the system, the system learns rules using this input sentence. As a result, the coverage of the sentence can be improved. Except for registering unknown words, there are two methods for learning the grammars. One is to add new production rules to the original CFG. The other is to add word pairs. After learning unknown words and production rules, we evaluate the coverage of sentences and perplexity using above methods. |
