Outline of Final Research Achievements

It is expected to construct a corpus to study the history of Japanese language today. To construct this corpus, it is necessary to perform automatic morphological analysis to annotate word information to various historical documents. However, there was no dictionary fitting for documents of Late Middle Japanese (in the Edo era) so far. Our purpose was to make it possible to analyze documents of the Edo era with a high accuracy necessary for the linguistic study. Expanding the entries of the existing dictionary and using a specific corpus for training data, we could analyze texts of kyogen and Sharebon with a high degree of accuracy. These dictionaries are used for the construction of the Corpus of Historical Japanese now.
