work on srl alignment
modification to the SRL alignment
change the mis-alignment between the result annotated by Stanford and the result got by SRL software
modify the EecbTopic stanford annotation part code, the reason is that every sentence its starting characteroffset should start at 0, if I put all rawText in a whole, then the characteroffset will increment along the way
make adjustment to align stanford tokenization result with the srl result
finish the SRl alignment by token span and head word, there is still one problem, that is several mentions has the same headinde. In the current implemention, we just keep one mention with the same head index. We need to keep all those mentions not just one
keep the shorter mention for the same head when adding the mentions according to their headIndex
