14th Information Retrieval Colloquium [PDF ebook] 
Proceedings of the BCS 14th Information Retrieval Colloquium, University of Lancaster, 13-14 April 1992

We hope that all readers will find the papers included in this volume of interest. All were presented at the 14th BCS IRSG Research Colloquium held at Lancaster University on 13th-14th April 1992. The papers display very well the scope and breadth of information retrieval, as indeed did the workshop ilself. They also present a good cross-section of current IR research, and as such provide a useful signpost for trends in information retrieval. Before we finish we must thank the following colleagues: Simon Botley, Paul Rayson and Paul Jones for their help in the organization of the conference. We would also like to extend a special message of thanks to Professor G.N. Leech of the Department of Linguistics at Lancaster and Roger Garside of the Department of Computing at Lancaster for their support during the conference period. Tony Mc Enery would also like to express his thanks and gratitude to Paul Baker for his help during the production of this book.
