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. |

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a system in which according to retrieval conditions inputted by a plurality of users, a check is made to determine whether or not the conditions are satisfied with respect to a text inputted such that the text inputted is delivered to users corresponding to the retrieval conditions satisfied to thereby deliver texts desired by the users.
To improve the problems above in accordance with the document retrieving and delivering method of the present invention, through the steps described below, similarity of each text acquired is calculated for a document (to be referred to as a seed document herebelow) containing information requested by the user to thereby deliver an appropriate text to the user.
Namely, the document retrieving and delivering method of the present invention includes a retrieval condition registering steps of registering retrieval conditions inputted from a plurality of users and a retrieval and delivery step for retrieving texts satisfying the retrieval condition from text data of document information and for delivering the texts retrieved to associated users.
The retrieval and delivery step includes calculating, from the texts, a ratio the text which matches the retrieval conditions (to be called similarity herebelow) and whether or not the retrieval conditions are satisfied is determined according to the similarity to deliver the text to the users corresponding to the retrieval conditions satisfied.
By the operation, similarity of the text acquired can be determined with respect to a document including information desired by the user to thereby appropriately deliver the text to the user.
The retrieval condition inputted from the user may be provided in the form of a document desired by the user.
In such a situation, retrieval conditions are generated according to the document in the present invention.
