Abstract(in English) | This paper describes a new method to acquire words automatically from a Japanese text. Morphological analysis is necessary to recognize words from a Japanese text. There exist, however, problems of unknown words recognition and ambiguity of compound words recognition, so dictionaries and complex heuristics are necessary to resolve them. This method is based on the N-gram method which need not traditional morphological analysis. It includes 2 steps: (1) calculation of Normalized Frequency for each substring included in the Japanese text using the N-gram statistics, (2) acquisition of the boundary between words. Experiments were done on EDR Japanese corpus. we obtained the correct recognition scores of 82.39% and the recall scores of 69.84%. |
