Member Function Documentation

bool Parser::TrainState::hasNext

(

)

[inline]

Returns:

whether this is a final state.

Reimplemented from Parser::State.

Referenced by Parser::EventStream::EoS(), Parser::EventStream::hasNext(), and Parser::MlpParser::parse().

Event * Parser::TrainState::next

(

)

[virtual]

Returns:

the training event, consisting of features representing the state.

Implements Parser::Iterator< Tanl::Classifier::Event * >.

References nextAction(), and Parser::State::predicates().

Referenced by Parser::EventStream::next(), and Parser::MlpParser::parse().

Action Parser::TrainState::nextAction

(

)

[protected]

Compute next parse action.

Determines the action (LRSEI) required to build the dependency tree.

In case of ArcEager, also generates P. In case of !CompositeAction, also generates D.

References dependents, Parser::State::extracted, Parser::State::input, Tanl::TreeToken::left, Tanl::TreeToken::right, and Parser::State::stack.
