To determine lack of necessary description in document data.
A morphologic analysis portion 3 analyzes morpheme in input document data stored by a storing device 2, and recognizes each paragraph in the document data with word class information of the paragraph. A syntax analysis portion 4 analyzes syntax of each paragraph by inputting a result of morphologic analysis, and creates a syntax tree indicating grammatical relationship of each paragraph as a result of syntax analysis. A determining portion 6 determines the presence of defect in a sentence in the input document data, that is, the paragraph for establishing grammatically correct sentence is not described, when the paragraph corresponding to a route of the syntax tree indicating a result of syntax analysis is not found. Here, the determining portion 6 creates a message indicating the deficiency in description necessary for establishing the grammatically correct sentence, and outputs the message to an output device 8.
