Abstract
Information discovery systems
range from controlled, static, topic-specific
collections of homogeneous documents to uncontrolled, highly dynamic,
collections of heterogeneous documents.
Techniques are required to
dispatch the user queries to
collections that are most
likely to contain documents satisfying
the information need of the user.
Dispatching queries in this way to find relevant documents is
the information discovery problem.
This paper surveys scalable solutions
that have been developed
to solve the information discovery problem.
In varying degree such developments have contributed
to query dispatch and document retrieval in uncontrolled,
heterogeneous information discovery systems.
Research in this area is motivated by the need for associative
access to documents in the Internet which is experiencing rapid
growth in terms of user base, data volume and information diversity.
We propose an abstract framework
that captures the main components of information discovery systems
and into which existing systems may be mapped.
Within the context of this framework we then suggest some related
research problems.
