- Abstract
- Computes low performance standards for each query and for the group of queries in 13 traditional and 4 TREC test collections. Predicted by the hypergeometric distribution, the standards represent the highest level of retrieval effectiveness attributable to chance. Compares operational levels of performance for vector-space, ad-hoc-feature-based, probabilistic, and other retrieval models to the standards. The effectiveness of these techniques in small, traditional test collections, can be explained by retrieving a few more relevant documents for most queries than expected by chance. The effectiveness of retrieval techniques in the larger TREC test collections can only be explained by retrieving many more relevant documents for most queries than expected by chance. The discrepancy between deviations form chance in traditional and TREC test collections is due to a decrease in performance standards for large test collections, not to an increase in operational performance. The next generation of information retrieval systems would be enhanced by abandoning uninformative performance summaries and focusing on effectiveness and improvements in effectiveness of individual queries

- Abstract
- TREC ia an annual conference held in the USA devoted to electronic systems for large full text information searching. The conference deals with evaluation and comparison techniques developed since 1992 by participants from the research and industrial fields. The work of the conference is destined for designers (rather than users) of systems which access full text information. Describes the context, objectives, organization, evaluation methods and limits of TREC

- Abstract
- The Text REtrieval Conference (TREC) workshop series encourages research in information retrieval from large text applications by providing a large test collection, uniform scoring procedures and a forum for organizations interested in comparing their results. Now in its seventh year, the conference has become the major experimental effort in the field. Participants in the TREC conferences have examined a wide variety of retrieval techniques, including methods using automatic thesauri, sophisticated term weighting, natural language techniques, relevance feedback and advanced pattern matching. The TREC conference series is co-sponsored by the National Institute of Standards and Technology (NIST) and the Information Technology Office of the Defense Advanced Research Projects Agency (DARPA)

- Abstract
- There have been 3 Text Retrieval Conferences (TREC) organized by the National Insitute of Standards and Technology (NIST) over the last 3 years which have compared retrieval results on fairly large databases (at least 1 gigabyte). The queries (called topics), relevance judgements and databases were all provided by NIST. The main goal of the tests was to compare various retrieval algorithms using various measures of retrieval effectiveness. When Tague-Sutcliffe performed an analysis of variance on the average precision there is a large group of systems at the top of the ranking which are not significantly different. In addition the queries contribute more to the mean square the systems. To gather further insight into the results, this research investigates the variations in query properties as a partial explanation for the variation in retrieval scores. For each topic statement for the queries, the length (number of content words), langth of various parts and total number of relevant documents are correlated with the average precision
