COMPOUND NOUN EXTRACTION DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a compound noun extraction device allowing extraction of a proper compound noun without describing a compound noun list or a detailed rule in advance. PSOLUTION: The compound noun extraction device morpheme-analyzes document data, thereafter refers to a speech part connection rule by speech part information of a morpheme, and obtains compound noun candidate data 150 with continuous morphemes as a compound noun candidate when the continuous morphemes fit the connection rule. The compound noun extraction device obtains a forward score of the head morpheme and a rearward score of the final morpheme in reference to character string frequency data about each head morpheme and each final morpheme constituting the compound noun candidate, and extracts a character string from the head morpheme to the final morpheme as the compound noun when both the scores are larger than a score set value.
