Abstract

A keyword creation method and its apparatus to simply create keywords in user'"'"'s retrieving a desired item of information from a vast amount of information. The habitual situation characteristics and the degree of typical liking tendency of a user are calculated on the basis of answers on daily items of the user, typical situation dependent keyword(s) of the user in one or more individual typical situations previously prepared is(are) created in accordance with the degree of typical liking tendency of the user and typical situation dependent keyword(s) is(are) revised in accordance with the habitual situation characteristics of the user, so that keyword(s) according to the actual situation of the user can be created.

Claims

1. A keyword creation method comprising the steps of:

inputting the answers of question items given to a user;

calculating the habitual situation characteristics of said user and the degree of typical liking tendency of said user on the basis of said answers;

creating a keyword of said user for each typical situation in one or more previously prepared typical individual situations on the basis of the degree of typical liking tendency of said user;

correcting said typical situation dependent keyword on the basis of habitual situation characteristics of said user to thereby create the keyword corresponding to the actual situation of said users;

a database step for storing collection data on samples of general liking attribute points serving as an element for calculating the degree of typical liking tendency of said user for said calculation step and ascription information calculation data for said collection information of said user; and

a keyword group database step for feeding a typical-situation dependent keyword to said typical situation dependent keyword creation step on the basis of the degree of a typical liking tendency of said user.

2. The keyword creation method according to claim 1, wherein:

said data base step has the stored data capable of being updated.

3. The keyword creation method according to claim 1, wherein:

said keyword group data base step has the stored data capable of being updated.

4. The keyword creation method according to claim 1, further comprising the step of:

retrieving a predetermined title in accordance with said specific situation keyword.

5. The keyword creation method according to claim 1, further comprising:

a title data base step for feeding the title corresponding to said specific situation keyword to said retrieval step.

6. The keyword creation method according to claim 1, wherein:

said title data base step has the stored data capable of being updated.
