Member Function Documentation

virtual void reranker::ExecutiveFeatureExtractor::Extract ( CandidateSet &  candidate_set ) const

pure virtual

Extracts features for the specified CandidateSet using the suite of FeatureExtractor instances specified at construction time.

Parameters

candidate_set

the CandidateSet for which to extract features

shared_ptr< ExecutiveFeatureExtractor > reranker::ExecutiveFeatureExtractor::InitFromSpec ( const string &  filename )

static

A convenience factory method that uses an internal Factory<ExecutiveFeatureExtractor> instance to construct an ExecutiveFeatureExtractor instance using the spec string contained in the specified file.

Definition at line 68 of file executive-feature-extractor.C.

virtual void reranker::ExecutiveFeatureExtractor::Reset ( ) const

pure virtual

Indictes to this instance that iteration has been reset.
