An Automatic System of Selective Dissemination of Information
Proceedings of the 70th IFLA General Conference and Council, Sao

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 users to keep themselves updated. It
is desirable to allow users to submit profiles, i.e., queries that
are constantly evaluated, so that they will be automatically informed
of new additions that may be of interest. Such service is traditionally
called Selective Dissemination of Information (SDI). The high document
arrival rate, the huge number of users, and the timeliness requirement
of the service pose a challenge in achieving efficient SDI. Instead
of being the active part in information access, researchers want
to be notified whenever a new paper in one�s research area is published.
In this article, we propose a model for SDI in a digital library
project in development at the School of Information Science at UFMG.
We describe the goals and main services this infrastructure will
provide
