INFORMATION RESEARCHING METHOD AND DEVICE THEREFOR, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To realize an information researching device capable of researching information with high accuracy by few learning data.

SOLUTION: This information researching device has: a tree generation part 11 generating a tree for vector quantization by the learning data previously classified in each category; a vectorization part 12 vectorizing the learning data and researching target data respectively by use of the tree; a similarity calculation part 13 calculating a similarity between a vector of the learning data and a vector of the researching target data; and a researching result list generation part 14 finding a researching result on the basis of the similarity. When feedback data to output of the researching result which is outputted is inputted, the vector of the learning data is improved by use of the feedback data, and the researching result is updated on the basis of a similarity between the improved vector and the vector of the researching target data.
