POSTER ANALYSIS DEVICE, PROGRAM, AND METHOD FOR ANALYZING PROFILE ITEM OF POSTER FROM POSTED SENTENCE

摘要

PROBLEM TO BE SOLVED: To provide a poster analysis device, etc., with which it is possible to estimate, from posted sentences of a user, the profile item (for example, a commodity or service) of the user as much accurately as possible.SOLUTION: The poster analysis device has: learning posted sentence storage means for storing a plurality of learning posted sentences and profile items in correlation thereto; learning predicate term structure extraction means for extracting a learning predicate term structure from the learning posted sentences; learning vector generation means for generating, for each profile item, a learning vector of the learning predicate term structure from each learning posted sentence; user predicate term structure extraction means for extracting a user predicate term structure from the user posted sentences of a poster; user vector generation means for generating, from the user posted sentences, a user vector of the user predicate term structure corresponding to a definition vector; and profile item estimation means for discriminating a learning vector most resembling the user vector using a learning vector group per profile item, and registering the profile item of the learning vector in correlation to the poster.SELECTED DRAWING: Figure 2
