| Outline of Final Research Achievements |
Identification of language correspondences between two different sets of language data is one of the main problems in world's languages matching. We proposed a method which enables this identification by using two measures of language name similarity and language classification similarity, having succeeded in searching 88% languages included in one set of language data that relate to another set of language data. We further improved the accuracy by taking into account brother information in a language classification tree.
Their method still has a problem, that is, their method gave an inappropriate decision even if either of these two similarities has a complete matching. To address this problem, we define two kinds of new measures: one is a similarity of languages based on brother information, and the other is a language general similarity that integrates the similarities of language name and language classification. The effectiveness of this method was confirmed by experiments.
