Abstract(in English) | In this paper, we describe an 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 regisering unknown words, there are three methods for learning the grammar. One is to add new production rules to the original CFG. The second is to add word pairs. The last is to add nonterminal symbol pairs. In the registering unknon words or not, we evaluate the coverage of sentences and perplexity using above methods.And we evaluate perplexity using bigram instead of word pairs. |
