Member Function Documentation

virtual double lemur::retrieval::ProxNode::eval (  const lemur::api::DocumentRep *  dRep  )  const [inline, virtual]

Score as the proximityScore for this document representation. Implements lemur::retrieval::QueryNode. Reimplemented in lemur::retrieval::TermQnode, and lemur::retrieval::PassageQNode.

double lemur::retrieval::ProxNode::proximityScore (  const lemur::api::DocumentRep *  dR, double  defaultScore )  const [inline, private]

evaluate proximity operator against a document Prunes proxList to remove any entries that are no longer relevant to scoring this operator.

virtual void lemur::retrieval::ProxNode::updateDocList (  int  numDocs  )  [inline, virtual]

Intersect the doc lists of the children of this node. Implements lemur::retrieval::QueryNode. Reimplemented in lemur::retrieval::OdnQNode, lemur::retrieval::UwnQNode, lemur::retrieval::PassageQNode, and lemur::retrieval::SynQNode.
