a) The VUSE (View-based User Search Engine) system for INSPEC
        presented by Dr Martin Smith
 
Abstract
CeDAR - The Centre for Database Access Research, School of Computing
and Mathematics, University of Huddersfield, UK, has pioneered the
use of view-based techniques to improve the effectiveness of user-
interfaces to both bibliographic and corporate databases.
The system presented is:
 
VUSE for INSPEC
 
This front-ending software searches the 5 million record INSPEC
database and is a by-product of a research project launched on 1st
Sept. 1991.  The project has been funded by the University of
Huddersfield in collaboration with the Institution of Electrical
Engineers,  Marconi Research Laboratories and STN-International
(FIZ-Karlsruhe).  The  VUSE (View-based User Search Engine) system removes
the need for the user to appreciate explicit Boolean statements by
introducing a search strategy of successive refinement through the
use of filtering views.  These techniques are described in ``Peek-a-Boo
revived --- End-user searching of bibliographic databases using
filtering views.'' by A Steven Pollitt, Martin P Smith and Geoffrey P
Ellis, Online 94, 18th International Online Information Meeting,
London, December 1994 pp 63-72.

FUN : An NF2 Relational Interface with Aggregation
      Capability for Document Retrieval, Restructuring and Analysis
 
Kalervo Jarvelin and Timo Niemi
 
Abstract
 
Complex documents are used in many environments, e.g., information
retrieval (IR). Such documents contain subdocuments, which may contain
further subdocuments, etc. In practice, document database users often
want to view selected complex documents in different structures and to
obtain aggregation information on their subdocuments. Therefore powerful
tools are needed for complex document retrieval, restructuring, and
analysis. The FUN system provides powerful filter conditions, full
restructuring capability and multi-attribute multi-level data aggregation of
structured complex documents represented in the non-first-normal-form
(NF2) relational model. In particular, The FUN system provides these
capabilities in a truly declarative and powerful interface.
