PPROBLEM TO BE SOLVED: To provide a determination factor for determining propriety of adoption of word information, which is given to an application program by vector notation of a word. PSOLUTION: In the first place, all the lemmas explained by an explanatory sentence are taken out from a dictionary DB 10, and a frequency of the lemmas appearing in each explanatory sentence is computed by an appearance frequency summarization part 11. Then, by means of a direct appearance probability computing part 12, an appearance probability of words in the explanatory sentence for the lemmas is computed from the frequency. By means of an indirect appearance probability computing part 13, it is assumed that the words in the explanatory sentence are indirectly explained by the explanatory sentence, and an appearance probability of the words in an indirect explanation sentence for the lemmas is computed. Then, by a direct/indirect appearance probability computing part 14, the direct and indirect appearance probabilities of the words in the explanatory sentence are added together for finding an appearance probability for all the explanatory words. Finally, by a vector notation storage part 15, the appearance probabilities of all the explanation words are taken out for each lemmas and stored as the vector notation in the word relation database 16.
