摘要

An information classification system includes a server including a knowledge base that receives classification information to be classified, conducts language analysis of the classification information to acquire and classify a plurality of keywords into elements made up of a classification target word and a related word that modifies the classification target word, and conducts a search with the related word, so as to assign a classification identification value to the information; a classification candidate extraction section that extracts the classification identification value that the knowledge base assigns to generate an automatic classification result; and a classification update section that receives the automatic classification result and corrects registered items in the knowledge base with a correction value received through a GUI for classification confirmation while referring to log data that is a processing history about automatic classification for the language analysis and the element classification.

1. An information classification system, comprising:
a knowledge base that receives classification information to be classified as a word string, conducts language analysis of the classification information to acquire a plurality of keywords that the classification information includes and classify the plurality of keywords into elements made up of a classification target word and a related word that modifies the classification target word, and conducts a search with the related word being for a judgment condition for decision of the classification while separating the classification target word from the related word, to assign a classification identification value to the information; a classification candidate extraction section that extracts the classification identification value that the knowledge base assigns to generate an automatic classification result; and a classification update section that receives the automatic classification result, displays a graphical user interface (GUI) for classification confirmation allowing confirmation of correctness of the automatic classification result, and corrects registered items in the knowledge base with a correction value received through the GUI for classification confirmation while referring to log data that is a processing history about automatic classification for the language analysis and the element classification; wherein the knowledge base comprises: a language analysis section that extracts a plurality of keywords from the classification information while referring to a word dictionary database; and a language element classification section that classifies the extracted plurality of keywords into the classification target word and the related word that modifies the classification target word by referring to a classification database and when a binary condition is registered for the classification target word, prioritizes a judgment based on the binary condition.
