FUTURE REPRESENTATION DISCRIMINATION DEVICE, FUTURE REPRESENTATION DISCRIMINATION METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a future representation discrimination device for discriminating a sentence whose content is future even when time is not clearly shown in such a sentence that "I wish rain falls".

SOLUTION: This future representation discrimination device is configured to count up the frequency of the appearance of identity representations registered in an identity dictionary in each processing object sentence of a text registered in a text database, and to add the values of the respective identities of the processing object sentences whose text numbers are equal to the frequency of appearance of the identity representations and a numerical value which is 0 or 1 showing the presence/no presence of the appearance of the identity representations by applying weight changing in accordance with an inter-sentence distance (the difference of sentence numbers) by using a text number unique to the text and a sentence number showing at what position the sentence appears in the text, and to create functions for discriminating whether or not the content of the discrimination object sentence is the future by performing mechanical learning on the basis of the value of the sentence whose content being future is already known among the values of the respective identifies output by a learning information synthesizing means.
