Title: Term collating method
Inventor: DAIKOUMIYOU NAOTAKA
IPC: G06K9/72
Filed: 1989-03-13
Abstract: PURPOSE:To decrease the throughput of recollating processing by evaluating the accuracy of N candidate terms by using a proper evaluation measure and removing candidate terms which are low in the probability of a correct answer from objects of recollating. CONSTITUTION:When it is decided by decision processing 4 that the recollating is necessary, narrowing-down processing 17 for the candidate terms wherein the N candidate terms which are passed to processing 13 are narrowed down into candidate terms which are high in the probability of the correct answer is carried out. In the narrowing-down processing 17 for the candidate terms, information with which the candidate terms high in the probability of the correct answer among pieces of information obtained by a term search part 5 is utilized as the evaluation scale. The threshold value of this evaluation measure is compared with evaluated values of evaluation measures of the respective candidate terms to determine only the candidate terms which have large evaluation measures as object candidates to be recollated. Thus, the candidate terms which are low in the probability of the correct answer are removed from the objects of processing of the recollating processing part 13 to reduce the load on the recollating processing without any decrease in correct answer ratio.
