Method and system for automatically identifying morphological information from a machine-readable dictionary

摘要

A method and system for determining the derivational relatedness of a derived word and a base word. In a preferred embodiment, the system includes a machine-readable dictionary containing entries for head words and morphemes. Each entry contains definitional information and semantic relations. Each semantic relation specifies a relation between the head word with a word used in its definition. Semantic relations may contain nested semantic relations to specify relations between words in the definition. The system compares the semantic relations of the derived word to the semantic relations of a morpheme, which is putatively combined with the base word when forming the derived word. The system then generates a derivational score that indicates the confidence that the derived word derives from the base word.
