Workshop on Challenges in Information Retrieval
and Language Modeling

September 11 -12, 2002
University of Massachusetts
Center for Intelligent Information Retrieval
Amherst, Massachusetts, USA

Workshop Purpose

The aim of the workshop is to bring together a group of leaders in information retrieval and language modeling to discuss what the challenges in information retrieval are and how language modeling approaches may be applied to information retrieval tasks to help solve some of these challenges. An expected outcome of the meeting is a report listing IR challenges (similar to the Asilomar Report on Database Research).

This workshop is by invitation only.
