Modeling score distributions for combining the outputs of search engines

R. Manmatha, T. Rath, F. Feng
2001 Proceedings of the 24th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '01  
Experiments show that this model fits TREC-3 and TREC-4 data for not only probabilistic search engines like INQUERY but also vector space search engines like SMART for English.  ...  We have also used this model to fit the output of other search engines like LSI search engines and search engines indexing other languages like Chinese.  ...  The first author would like to thank Bruce Croft for extensive discussions and also for pointing out relevant literature especially previous literature on score modeling in information retrieval.  ...

The effect multiple query representations on information retrieval system performance

Nicholas J. Belkin, C. Cool, W. Bruce Croft, James P. Callan
1993 Proceedings of the 16th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '93  
These different formulations were grouped, and the groups, and combinations of them, were used as searches against the TREC test collection, using the INQUERY probabilistic inference network retrieval  ...  The issue of recall as a performance measure in large databases was raised, since overlap between the searches conducted in this study, and the TREC-1 searches, was smaller than expected.  ...  To do this, we compare it to the performance of the current best version of the INQUERY indexinglrepresentation routines and retrieval techniques, which have been optimized for the TREC collection.  ...

Structured queries, language modeling, and relevance modeling in cross-language information retrieval

Leah S. Larkey, Margaret E. Connell
2005 Information Processing & Management  
Two probabilistic approaches to cross-lingual retrieval are in wide use today, those based on probabilistic models of relevance, as exemplified by INQUERY, and those based on language modeling.  ...  INQUERY, as a query net model, allows the easy incorporation of query operators, including a synonym operator, which has proven to be extremely useful in cross-language information retrieval (CLIR), in  ...  Title and description fields from two query sets were used -twenty-five queries from TREC 2001, and fifty queries from TREC 2002.  ...

Applications of Score Distributions in Information Retrieval [chapter]

R. Manmatha
2003 Language Modeling for Information Retrieval  
This model fits not only probabilistic search engines like INQUERY but also vector space search engines like SMART and also LSI search engines.  ...  A number of different IR tasks may benefit from score modeling including filtering, multi-lingual retrieval and relevance feedback.  ...  Figure 5 shows recall-precision plots for combining INQUERY and SMART on TREC-3 data.  ...

1999 Proceedings of the 22nd annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '99  
The databases from our testbed were ranked using both the gGlOSS and CORI techniques and compared to a baseline derived from TREC relevance judgements.  ...  The testbed is a decomposition of the TREC TIPSTER data into 236 subcollections.  ...  Queries were based on TREC topics 51-150 and 301-350. We used query sets INQ001, INQ026, and INQ411, all created by the UMass CIIR as part of its participation in TREC and Tipster evaluations 1, 6 .  ...
