| Outline of Final Research Achievements |
Applying generation techniques of gene phylogenetic-tree to the linguistic research field, we proposed several methods of generating language family-trees. Firstly, a computation model was proposed to measure inter-language distances by using edit distance and Jaro-winkler distance based on basic vocabulary. Then, a model was constructed to involve those linguistic features that are considered to have high influence on language classifications by applying the method of feature extraction by random forest. Regarding grammatical structure as a language feature, the grammatical differences of languages were focused on and the characteristics of each language were described by the generation rules in the surface layering process of Fillmore’s case grammar. Finally, the concordance problem in grammar was solved by applying of unification grammar. This made it possible to formalize grammar data used in grammar analyzing.
