parse

public SentenceData09 parse(SentenceData09 instance,
                   ParametersFloat params,
                   boolean labelOnly,
                   OptionsSuper options)

Returns:

apply

public SentenceData09 apply(SentenceData09 snt09)

Description copied from interface: Tool

Uses the tool and applies it on the input sentence. The input is altered and has to include a root (token).

Specified by:

apply in interface Tool

Returns:

The result of the performance without the root.

getInfo

public float[] getInfo()

Get the edge scores of the last parse.

Returns:

the scores

retrain

public boolean retrain(SentenceData09 sentence,
              float upd,
              int iterations)

Description copied from interface: Retrainable

Retrains with a update factor (upd). The retraining stops when the model was successful adapted or it gave up after the maximal iterations.

Specified by:

retrain in interface Retrainable

Parameters:

sentence - the data container of the new example.

upd - the update factor, e.g. 0.01

iterations - maximal number of iterations that are tried to adapt the system.

Returns:

success = true -- else false

retrain

public boolean retrain(SentenceData09 sentence,
              float upd,
              int iterations,
              boolean print)

Specified by:

retrain in interface Retrainable
