Information filtering method and apparatus for preferentially taking out information having a high necessity
First Claim
1. An adaptive dictionary apparatus with which a keyword effective for judging whether or not information provided from either one of an information recording medium or an information communication network is recorded preferentially into a dictionary, the information including information data and one or more keywords attached to the information data, the apparatus comprising:
- information providing means for providing a user with the information data;
inputting means for enabling the user to input a signal indicating that the provided information data is necessary or unnecessary;
learning means for calculating a prediction value for predicting a user'"'"'s necessity degree of each keyword attached to the provided information data on the basis of the signal inputted by the inputting means; and
dictionary updating means for preferentially registering the keyword effective for the dictionary by using the prediction value.

Abstract
A method and apparatus are provided of adapting a dictionary into which a keyword effective for judging whether or not information provided from either one of an information recording medium or an information communication network is recorded preferentially. The information includes information data and one or more keywords attached to the information data. The method is implemented by providing a user with the information data, enabling the user to input a signal indicating that the provided information data is necessary or unnecessary; calculating a prediction value for predicting a user'"'"'s necessity degree of each keyword attached to the provided information data on the basis of the signal inputted in the inputting step, and registering preferentially the keyword effective for the dictionary by using the prediction value.

means for memorizing both the total number of affirmative responses indicating that the signal inputted by the inputting means shows that the provided information data is necessary and the total number of negative responses indicating that the signal inputted by the inputting means shows that the provided information data is unnecessary;
a table used for converting a character stream showing each keyword signal into a numeral;
an adaptive dictionary memory for memorizing both the number of affirmative times showing that the information including the character stream as the keyword signal is necessary and the number of negative times showing that the information including the character stream as the keyword signal is unnecessary; and
a dictionary learning unit for updating the total number of affirmative responses, the total number of negative responses, and a signal showing the times memorized by the adaptive dictionary memory on the basis of the signal inputted by the inputting means, the keyword signal included in the information, the total number of affirmative responses, the total number of negative responses, and the signal showing the times memorized by the adaptive dictionary memory.

7. A method of adapting a dictionary into which a keyword effective for judging whether or not information provided from either one of an information recording medium or an information communication network is recorded preferentially, the information including information data and one or more keywords attached to the information data, the method comprising the steps of:
-
providing a user with the information data;
enabling the user to input a signal indicating that the provided information data is necessary or unnecessary;
calculating a prediction value for predicting a user'"'"'s necessity degree of each keyword attached to the provided information data on the basis of the signal inputted in the inputting step; and
registering preferentially the keyword effective for the dictionary by using the prediction value. - View Dependent Claims (8, 9, 10)
