Query Processing for Information Distribution

top right

We examine the problem of selective information distribution to a large user community. As information is created it is compared to interest profiles and distributed to those persons who have indicated a desire to receive it. Unlike traditional information retrieval systems we cannot take advantage of off-line analysis (indexing) of the data to be queried. Unlike transaction processing systems, the data is primarily textual. We can and do, however, preprocess the users' queries.
