PURPOSE:To accurately analyze grammatical and meaning information included in a natural language sentence by using a functional declinable word coupling table. CONSTITUTION:In case of analyzing a natural language sentence including functional declinable word coupling, an extracting part 2 extracts the functional declinable word coupling from the natural language sentence inputted from an input device by using the functional declinable word coupling table 4 describing information relating to the declinable using method of a wide action noun capable of functional declinable word coupling in each functional declinable word, the information of words modifying the action noun, the grammatical parts (aspect, voice, etc.) included in the functional declinable word, and the information of words modifying the functional declinable word. An analyzing part 7 uses a word obtained by declinating a wide action noun in the natural language sentence as a declinable word and adds the grammatical part included in the functional declinable word to the natural language sentence to analyze the sentence. Thus, the functional declinable word coupling can be analyzed as grammatical meaning.
