Constructor Detail

ParserEventStream

public ParserEventStream(ObjectStream<Parse> d,
                         HeadRules rules,
                         ParserEventTypeEnum etype,
                         Dictionary dict)

Create an event stream based on the specified data stream of the specified type using the specified head rules.

Parameters:

d - A 1-parse-per-line Penn Treebank Style parse.

rules - The head rules.

etype - The type of events desired (tag, chunk, build, or check).

dict - A tri-gram dictionary to reduce feature generation.
