Detailed Description

Application specific parameters.

This is a sample application that does distributed retrieval, using a resource selection index and individual indexes. resource selection is done using the CORI_CS (the only resource selection implemented thus far). results merging uses either CORIMergeMethod (The retrieval method of each individual databases should be CORI_DOC) or SingleRegrMergeMethod (The retrieval method of each individual databases should be CORI_DOC).

Parameters should be set as follows: index = the collection selection database collCounts = collection counts file for the csindex (needed by CORI) ranksFile = file to write rankings results to (optional) resultFile = file to write final results resultCount = maximum number of results to output for each query (default to 1000) textQuery = file of text queries in docstream format cutoff = maximum number of databases to search (default to 10) "dbids" = "db's param file" - required for each database in the collection selection index. key should be the dbcharid and value should be name of file that has parameters for that database: index = the individual database retModel = the retrieval model to use mergeMethod = the merging method to use "modelvals" - whatever parameters are required for that retModel CSTF_factor The TFfactor parameter in the CORI_CS resource selection method.

CSTF_baseline The TFbaseline parameter in the CORI_CS resource selection method.

mergeMethod resource merging method (0 for CORI results merging method, 1 for single regression results merging method)

Merginge Method-specific parameters:

For CORI mergine Method: None

For Single regression merging method:

1. csDbDataBaseIndex the centralized sampling database index

2. DOCTF_factor The TFfactor parameter in the CORI_DOC retrieval method for the centralized sampling database.

3. DOCTF_baseline The TFbaseline parameter in the CORI_DOC retrieval method for the centralized sampling database.
