Information processing device, information processing method, program for information processing device, and recording medium

An information processing method of an information processing device that performs information processing, comprising:

• a base word acquisition step of acquiring a base word to be a base;
• a compound word acquisition step of acquiring a compound word in which the base word acquired in the base word acquisition step becomes a modifiee from a compound word storage unit;
• a classification item acquisition step of acquiring classification items to classify the compound word acquired in the compound word acquisition step by referring to a classification item storage unit, the classification item storage unit storing predetermined classification items that are set in advance;
• a feature information acquisition step of acquiring feature information about a feature that provides a clue to classify the compound word acquired in the compound word acquisition step by referring to a feature information storage unit;
• a compound word classification step of distributing the compound word containing the base word into the classification item acquired in the classification item acquisition step, the classification item being set in advance and stored in the classification item storage, using a classification model generated in advance and the feature information acquired in the feature information acquisition step for the compound word acquired in the compound word acquisition step;
• a base word related information acquisition step of acquiring base word related information containing a plurality of elements related to the base word based on the base word;
• a base word related information classification step of classifying each of a portion of the elements contained in the base word related information acquired in the base word related information acquisition step into one of the classification items in accordance with a classification result in the compound word classification step;
• and
• an output step of outputting, to be displayed on a screen of a display of a user terminal device, the base word related information classified in the base word related information classification step along with an indication of the classification item into which the base word related information is classified.

A non-transitory recording medium computer-readably recording a program for an information processing device causing

• a computer to function as:
• a base word acquisition unit that acquires a base word to be a base;
• a compound word acquisition unit that acquires a compound word in which the base word acquired by the base word acquisition unit becomes a modifiee from a compound word storage unit;
• a classification item acquisition unit that acquires classification items to classify the compound word acquired by the compound word acquisition unit by referring to a classification item storage unit, the classification item storage storing predetermined classification items that are set in advance;
• a feature information acquisition unit that acquires feature information about a feature that provides a clue to classify the compound word acquired by the compound word acquisition unit by referring to a feature information storage unit;
• a compound word classification unit that distributes the compound word containing the base word into the classification item acquired by the classification item acquisition unit, the classification item being set in advance and stored in the classification item storage, using a classification model generated in advance and the feature information acquired by the feature information acquisition unit for the compound word acquired by the compound word acquisition unit;
• a base word related information acquisition unit that acquires base word related information containing a plurality of elements related to the base word based on the base word;
• a base word related information classification unit that classifies each of a portion of the elements contained in the base word related information acquired by the base word related information acquisition unit into one of the classification items in accordance with a classification result by the compound word classification unit;
• and
• an output unit that outputs, to be displayed on a screen of a display of a user terminal device, the base word related information classified by the base word related information classification unit along with an indication of the classification item into which the base word related information is classified.
