Index structures for selective dissemination of information
Abstract: "The number, size, and user population of bibliographic and full text document databases are rapidly growing. With a high document arrival rate, it becomes essential for users of such databases to have access to the very latest documents; yet the high document arrival rate also makes it difficult for the users to keep themselves updated. It is desirable to allow users to issue queries that are constantly evaluated, called standing orders, so that they will be automatically informed of new additions that may be of interest. Such service is traditionally called Selective Dissemination of Information. The huge number of users and the timeliness requirement of the service pose a challenge.

- "In this paper, we propose several index structures for standing orders and algorithms that efficiently match documents against large number [sic] of orders. We also present analysis and simulations results to compare their performance under different scenarios.""@en
