Keyword creation method and its apparatus
View Patent ↗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.
1. An apparatus comprising:
a user interface for enabling a user to input data which is used to create user preference information,
wherein the user preference information is generated by a three-axis attribute classification space, such that attribute points plotted on the classification space form clusters;
a user's preference database for storing said created user preference information;
a processor for determining one or more programs which may be of interest to the user by use of said user's preference database and program guide information; and
a display processor for generating a display signal representing a screen which includes a list of said determined programs;
wherein a liking attribute ascribability data array being a numerical array and indicating the degrees of the liking attribute of a user to be ascribed to respective adjacent clusters are calculated,
wherein said user interface enables said user to select one program from said displayed list for viewing,
wherein each axis of said three-axis attribute classification space represents a directionality of the user, and
wherein values indicating individual directionalities on the three-axis attribute classification space are established by an answer analysis processing module based on the input data.
2. The apparatus according to claim 1 , further comprising a decoder for decoding compressed video and audio signals which represent said selected program.
3. The apparatus according to claim 1 , further comprising a program guide receiver for receiving program guide information and a program guide database for storing received program guide information.
4. The apparatus according to claim 1 , further comprising a tuner for receiving a television signal and wherein said user's preference database stores tuning history data of said tuner.
5. The apparatus as claimed in claim 1 wherein the clusters are updated.
6. A method comprising the steps of: enabling a user to input data which is used to create user preference information by use of a user interface,
wherein the user preference information is generated by a three-axis attribute classification space, such that attribute points plotted on the classification space form clusters;
storing said created user preference information in a user's preference database;
determining one or more programs which may be of interest to the user by use of said user's preference database and program guide information; and
generating a display signal representing a screen which includes a list of said determined programs;
calculating a liking attribute ascribability data array being a numerical array and indicating the degrees of the liking attribute of a user to be ascribed to respective adjacent clusters;
wherein said user interface enables said user to select one program from said displayed list for viewing,
wherein each axis of said three-axis attribute classification space represents a directionality of the user, and
wherein values indicating individual directionalities on the three-axis attribute classification space are established by an answer analysis processing module based on the input data.
7. The method according to claim 6 , further comprising the step of decoding compressed video and audio signals which represent said selected program.
8. The method according to claim 6 , further comprising the steps of receiving program guide information and storing received program guide information.
9. The method according to claim 6 , further comprising the step of receiving a television signal by use of a tuner and wherein tuning history data of said tuner is stored in said user's preference database.
10. The method as claimed in claim 6 , further comprising:
updating the clusters.
