Member Function Documentation

Enumerator<std::vector<Token*>*>* Tanl::NER::NER::pipe

(

Enumerator< std::vector< Token * > * > &

tve

)

[virtual]

Create a pipe pulling from an Enumerator tve.

Returns:

an Enumerator connected in pipeline to

Parameters:

tve.

Implements Tanl::IPipe< std::vector< Token * > *, std::vector< Token * > * >.

vector< Token * > * Tanl::NER::NER::tag	(	std::vector< Token * > *	sent,
		NerEventStream *	eventStream = 0
	)

Tag the sentence sent, in the context of an eventStream which holds global document information.

Returns:

the same sentence with added annotations.
