Parser

public Parser(ParserModel model,
 int beamSize,
 double advancePercentage)

Instantiates a Parser via a given model and other configuration parameters. Uses the default implementations of POSTaggerME and ChunkerME.

Parameter:

model - The ParserModel to use.

beamSize - The number of different parses kept during parsing.

advancePercentage - The minimal amount of probability mass which advanced outcomes must represent. Only outcomes which contribute to the top advancePercentage will be explored.

Löst aus:

IllegalStateException - Thrown if the ParserType is not supported.
