Detailed Description

Abstract interface for distributed retrieval merging of scores.

Merge scores from individual databases. See RetrievalMethod for database ranking algorithms (CORIRetMethod). See DistSearchMethod for multiple individual database retrieval.

Member Function Documentation

void lemur::distrib::DistMergeMethod::mergeScoreSet (  const lemur::api::IndexedRealVector &  indexset, const DocScoreVector *const *  scoreset, DocScoreVector &  results )  [virtual]

merge a set of scores that were obtained from retrieval on the individual databases in the indexset. return the merged results into a DocScoreVector. The scores in scoreset should correlate with the indexes in indexset. Reimplemented in lemur::distrib::MultiRegrMergeMethod.

virtual double lemur::distrib::DistMergeMethod::score (  double  dbscore, double  docscore )  const [protected, pure virtual]

create a score for the merge based on the index ranking score and the document score Implemented in lemur::distrib::CORIMergeMethod, lemur::distrib::MultiRegrMergeMethod, and lemur::distrib::SingleRegrMergeMethod.
