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.
