Acknowledgements
Thanks to Stephen Robertson and Stephen Walker for making
OKAPI available to UCLA.
We are especially thankful to Stephen Walker for all his con-
tinuing help over and above that indicated in the text.
We wish to thank Donna Harman of NIST for her support
during TREC-2.
This research was supported by a UCLA Academic Senate
grant that also provided financial support for the graduate re-
search assistantship of PVB.
Finally, ENE is grateful to SUN Microsystems Inc. for the
equipment grant of the SPARC 2 that made this research p05-
sible.

A Runs
The runs presented here are grouped by algorithm used for the
expansion. The list starts with runs that did not include query
expansion.
