<P>PROBLEM TO BE SOLVED: To provide means for precisely estimating attribute information from an arbitrary symbol string. <P>SOLUTION: The information processing device includes: an input section that inputs plural symbol strings and attribute information to be extracted from each of the symbol strings; a feature quantity function generating section that generates plural feature quantity functions by selecting plural functions from a predetermined function group including a function for converting the symbol string into a numerical value and combining the plural functions, and outputs a feature quantity from symbol strings; a feature quantity calculation section that inputs each of the symbol strings to each of the feature quantity functions to calculate a feature quantity corresponding to each of the symbol strings; an estimation function generating section that generates an estimation function for estimating attribute information from the feature quantity by performing mechanical leaning by using the attribute information corresponding to each symbol string and the feature quantity corresponding to each of the symbol strings; and an output section that outputs the feature quantity function generated by the feature quantity function generating section and the estimation function generated by the estimation function generating section. <P>COPYRIGHT: (C)2012,JPO&INPIT |
