Possible bug in DataReader.py when loading vocab from dialogues

[garygsw]

Hi, I would like to clarify if this is a bug.

NNDIAL/loader/DataReader.py

Lines 876 to 880 in 740f6d3

	# user side
	words = self.delexicalise(turn['usr']['transcript']).split()
	mwords,words,_,_,_ = self.extractSeq(turn['sys']['sent'],\
	type='source',index=False)
	ivocab.extend(mwords)

Should the extractSeq method in line 878 be called on turn['usr']['transcript'] instead?

The words variable in line 877 is totally ignored, and replaced by the return values of extractSeq in line 878.
