摘要

A string matching unit 110 specifies a category of an input document 801 by string matching of the input document 801 and a classifying keyword shown by matching condition information 109. Learning data 209 shows statistic information of each category. A classifying unit 220 specifies the category of the input document 801 based on a correspondence ratio of the input document 801 and the statistic information shown by the learning data 209. A correct answer comparing unit 120 compares the category specified by the string matching unit 110 and a category of correct answer information 803. A learning unit 210 compares the category specified by the classifying unit 220 and the category of the correct answer information 803. An error rate calculating unit 310 calculates a classifying error rate of a string matching filter unit 100 and a learning filter unit 200 based on the comparison result of the correct answer comparing unit 120 and the comparison result of the learning unit 210. A result outputting unit 320 outputs the category specified by the filter having a smaller classifying error rate as a classified result 301 of a classifying target document 804.
