SIGIR 2004 Workshop:

RIA and "Where Can IR Go From Here?"

In the summer of 2003, NIST organized a 6-week workshop called Reliable Information Access or RIA (sponsored by ARDA). The RIA workshop brought together seven different top research IR systems and investigated how the systems were getting their results, and why the systems failed on some topics and succeeded on others. The SIGIR 2004 workshop will focus on discussing the implications of lessons learned from RIA; how they affect our understanding of what is currently happening in research systems, and what they suggest are areas of IR research that warrant immediate concentrated work. Some of the most important lessons have to do with how to study IR systems, and how to make use of multiple IR systems to sharpen our understanding of the principles behind the performance observed. This is a significant change in IR research over the "single lab model" which has been dominant up to now.

One of the major products of the RIA workshop is a massive (over 40 GBytes) database, including intensive manual failure analyses on 45 TREC topics and why each system failed on those topics. The database also includes over 3,000 total runs done by these research systems over 9 different TREC test collections. This database will be publicly available after the SIGIR workshop as a resource for the research community.

Because the main goal of the workshop is presentation to a wider audience of what occurred in RIA, and lots of discussion with the audience, the talks are all given by RIA workshop participants. Each of these participants will be presenting their work at the workshop, their work since that workshop, and a list of questions to the audience to provoke discussion of how others see the issues.
