14. A program, embodied on a non-transitory computer readable storage medium, and executable by an information classification apparatus that classifies information by assigning a classification identification value to the information, the program causing the information classification apparatus to execute the steps of: receiving classification information to be classified as a word string, and conducting language analysis of the classification information; acquiring a plurality of keywords that the classification information includes, classifying the plurality of keywords into elements made up of a classification target word and a related word that modifies the classification target word, and conducting 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, so as to assign the classification identification value to the information; extracting the assigned classification identification value to generate an automatic classification result; receiving the automatic classification result, and displaying a GUI for classification confirmation allowing confirmation of correctness of the automatic classification result; and correcting registered items in a knowledge base with a correction value received through the GUI for classification confirmation while referring to log data about automatic classification for the language analysis and the element classification; wherein the language analysis conducting step comprises the step of extracting a plurality of keywords from the classification information while referring to a word dictionary database; and the classification identification value assigning step comprises the steps of classifying 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, prioritizing a judgment based on the binary condition.

The program according to claim 14 , wherein the word dictionary database includes a morpheme keyword, an expression instability keyword, and a higher/lower level concept keyword registered therein, the classification database includes a main classification table, an auxiliary classification table, a binary condition table, and an additional attribute registered therein, the main classification table associating the classification target word with the classification identification value, the auxiliary classification table associating the related word that modifies the classification target word with a semantic attribute, the binary condition table associating a binary condition set and extracted from the related word registered in the auxiliary classification table with a judgment result using the binary condition, and the additional attribute modifying the classification target word, and the registered item correcting step comprises the steps of receiving correction of a reference condition for correcting a binary condition or a weighting via the GUI for classification confirmation, and updating the binary condition table with a value of the corrected binary condition or the additional attribute.
