Method Detail

decode

public static Parse decode(short[] pos,
           DataFES x,
           boolean projective,
           boolean training)
                    throws InterruptedException

Build a dependency tree based on the data

Parameters:

pos - part-of-speech tags

x - the data

projective - projective or non-projective

edges - the edges

Returns:

a parse tree

Throws:

InterruptedException

rearrange

public static void rearrange(short[] pos,
             short[] heads,
             short[] labs,
             DataFES x,
             boolean training)
                      throws InterruptedException

This is the parallel non-projective edge re-arranger

Parameters:

pos - part-of-speech tags

heads - parent child relation

labs - edge labels

x - the data

edges - the existing edges defined by part-of-speech tags

Throws:

InterruptedException

getInfo

public static String getInfo()
