<p><P>PROBLEM TO BE SOLVED: To estimate an attribute to be given to a word having an unknown attribute, by utilizing data of other words. <P>SOLUTION: Patterns of words co-occurring with an input word are extracted as feature patterns, and co-occurring words matching the feature patterns are extracted from word input co-occurrence data as synonym candidates of the input word, and a pattern of co-occurring words is extracted as a feature pattern with respect to the input word and each synonym, and this feature pattern is taken as an element to generate a vector having its co-occurrence frequency as a value. Degrees of association between the input word and respective synonym candidates are calculated, and synonym candidates of which the degrees of association with the input word are high are extracted as synonyms. Categories of the synonyms are checked to estimate a category to which the most synonyms belong, as a category of the input word, and the word to which the category is given as an attribute is outputted as the word with the attribute. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
