Abstract:
1. An information filtering system comprising: a first filter unit inputting document data belonging to at least any kind among a plurality of kinds from an input equipment, carrying out a predetermined classifying process to specify a kind to which the document data inputted belongs using a CPU (Central Processing Unit), and specifying the kind to which the document data inputted belongs as first classified information; a second filter unit inputting the document data from an input equipment, carrying out a predetermined classifying process being different from the classifying process of the first filter unit using a CPU, specifying a kind to which the document data inputted belongs as second classified information; a first correct answer comparing unit comparing the first classified information of a plurality of pieces of learning document data specified by the first filter unit with treating each of the plurality of pieces of learning document data which belongs to a kind previously specified as the document data and correct answer information of the plurality of pieces of learning document data which belongs to the kind previously specified using a CPU, generating first learning result information of the plurality of pieces of learning document data showing whether the first classified information matches the correct answer information or not based on comparison result, and storing the first learning result information generated of the plurality of pieces of learning document data in a memory equipment; a second correct answer comparing unit comparing the second classified information of the plurality of pieces of learning document data specified by the second filter unit with treating each of the plurality of pieces of learning document data as the document data and the correct answer information of the plurality of pieces of learning document data using a CPU, generating second learning result information of the plurality of pieces of learning document data showing whether the second classified information matches the correct answer information based on comparison result, and storing the second learning result information generated of the plurality of pieces of learning document data in a memory equipment; an error rate calculating unit calculating a first error rate showing a rate that the first classified information does not match the correct answer information based on the first learning result information of the plurality of pieces of learning document data generated by the first correct answer comparing unit using a CPU, and as well calculating a second error rate showing a rate that the second classified information does not match the correct answer information based on the second learning result information of the plurality of pieces of learning document data generated by the second correct answer comparing unit using a CPU; and a result outputting unit specifying a kind to which the classifying target document data belongs using a CPU based on the first classified information specified by the first filter unit with treating classifying target document data which is a target to be classified to a specific kind as the document data, the second classified information specified by the second filter unit with treating the classifying target document data as the document data, the first error rate calculated by the error rate calculating unit, and the second error rate calculated by the error rate calculating unit, and outputting the kind specified to an output equipment as a classified result.
