Method Detail

getMap

public static Map<Pair<Integer,String>,List<Triple<Integer,String,Double>>> getMap(String filename)

scoreTB

public double scoreTB(edu.stanford.nlp.parser.lexparser.Dependency dependency)

Description copied from interface: DependencyGrammar

Score a Dependency according to the grammar.

Specified by:

scoreTB in interface DependencyGrammar

Overrides:

scoreTB in class MLEDependencyGrammar

Parameters:

dependency - The dependency object to be scored, where the tags in the dependency have already been mapped to a reduced space by a tagProjection function.

Returns:

The negative log probability given to the dependency by the grammar. This may be Double.NEGATIVE_INFINITY for "impossible".

setLex

public void setLex(Lexicon lex)

finalize

protected void finalize()
                 throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable
