Member Function Documentation

virtual double PassageQNode::eval (  const DocumentRep *    dR )  const [inline, virtual]

Score as the maximum passage score for the document rep normalized by window size. The StructQueryDocRep provides passage iteration over the overlapping windows. The score for an individual passage is the sum of the scores of the children nodes. Reimplemented from ProxNode.

virtual void PassageQNode::updateDocList (  int    numDocs )  [inline, virtual]

Intersect the doc lists of the children of this node. Reimplemented from ProxNode.
