1. An information selecting apparatus comprising:

  • a feature data list containing a plurality of index values of a plurality of feature data previously set and indicative of various sorts of featured contents of a plurality of contents information including at least one of voice information, picture information, and text information;

    user-dependable sensitivity tables, which can be updated and include a plurality of correlative values between the plurality of feature data and a plurality of retrieve keys used to retrieve the plurality of contents information;

    acquiring means for acquiring the retrieve key;

    selection means operated in such a manner that when one retrieve key is acquired by the acquiring means, at least one contents information, which is coincident with the one retrieve key, is selected from the plurality of contents information on the basis of both the sensitivity table and the feature data list;

    judgment means for judging as to whether or not each of the selected contents information is coincident with the one retrieve key on the basis of an individual judgment by a user;

    first statistical processing means for quantifying relevancy between the one retrieve key and each of the plurality of feature data, with respect to the contents information judged to be coincident with the one retrieve key by the judgement means, in a statistical manner based on the index values with respect to the feature data stored in the corresponding feature data list to obtain a coincident index amount;

    second statistical processing means for quantifying relevancy between the one retrieve key and each of the plurality of feature data, with respect to the contents information judged not to be coincident with the one retrieve key by the judgement means, in a statistical manner based on the index values with respect to the feature data stored in the corresponding feature data list to obtain a incoincident index amount;

    calculation means for calculating a new correlative values between the one retrieve key and the plural feature data, respectively, based on the coincident index amount and the incoincident index amount; and

    update means for updating a portion of the sensitivity table, which is related to the one retrieve key, by using the new correlative value calculated by the calculation means.
