Abstract
Retrieval conditions inputted from a plurality of users are registered. According to the retrieval conditions, a retrieval is conducted for a text inputted. As a result of the retrieval, similarity of the text is calculated for each retrieval condition. The text is delivered to users of which the retrieval condition satisfies the similarity.
Claims20
A document retrieving and delivering method of delivering a text to a user, the text satisfying a retrieval condition obtained from said user, the method comprising the steps of:
- obtaining a retrieval condition from each of a plurality of users;
- correlating a delivery condition written in each said retrieval condition with a user identifier of each of said users and storing said delivery conditions in a memory;
- calculating similarity of text to each said retrieval condition;
- and
- delivering the text to the user having the user identifier which is stored in correlation with said delivery condition written in the retrieval condition calculated to have said similarity to said text, if the similarity of the text to the retrieval condition obtained from the user at least meets the delivery condition.
A document retrieving and delivering apparatus, comprising:
- registering means for registering retrieval conditions inputted from a plurality of users;
- and
- retrieval means for retrieving one of the retrieval conditions from each of the plurality of users,
- means for correlating a delivery condition written in each said retrieval condition with a user identifier of each of the plurality of users;
- means for storing the correlated delivery conditions in a memory;
- means for calculating similarity of a test to each said retrieval condition;
- and
- means for delivering the text to the user having the user identifier which is stored in correlation with said delivery condition written in the retrieval condition calculated to have said similarity to said text, if the similarity of the text to the retrieval condition obtained from the user at least meets the deliver condition.
A document retrieving and delivering program which, when executed by a computer, causes the computer to perform a method wherein a retrieval condition is obtained from each of a plurality of users, a delivery condition written in each said retrieval condition is correlated with a user identifier of each of said users and stored in a memory, similarity of a text to each said retrieval condition is calculated, and the text is delivered to the user having the user identifier which is stored in correlation with said delivery condition written in the retrieval condition calculated to have said similarity to said text if the similarity of the text to the retrieval condition obtained from the user at least meets the delivery condition.
