Abstract
This paper constitutes a proposal for an efficient and effective logical
information retrieval system. Following a relational indexing approach, which
is in our opinion a necessity to cope with the emerging applications such as
those based on multimedia, we use the conceptual graphs formalism as our
indexing language. This choice allows for relational indexing support and
captures all the useful properties of the logical information retrieval model,
in a workable system. First order logic and standard in formation retrieval
techniques are combined together, to the same effect: obtaining an expressive
system, able to accurately handle complex documents, improve retrieval
effectiveness, and achieve good time performance. Experimentations on an image
test collection, within a system available on the Web, provide an illustration
of the role that logic may have in the future development of information
retrieval systems.
