Abstract
The classical paradigm of finding information in the WWW by initiating
retrieval and browsing becomes more and more ineffective. Other
techniques in the context of digital libraries have to be considered.
Automatic delivery of contents to the user according to her needs and
filtered by her profile of interests is required.
Current implementations of such alerting services at content
providers side have several drawbacks, e.g. users interest cannot be
defined appropriately. In this paper we present an architecture for
an alerting service within a general framework of events.
Two competing technologies, Netscape's Netcaster and Active Channels
by Microsoft, have been proposed for implementing alerting services.
Both technologies will be evaluated
according to the requirements
of a digital library alerting service.
