Data reading is denied

The command python online_pmi.py data data/IELex-2016.tsv.asjp gives the following error:
online_pmi.py: error: argument data: can't open 'data': [Errno 13] Permission denied: 'data'

The arguments starting without dashes are positional arguments filled with the file names. So you would want python online_pmi.py data/IELex-2016.tsv.asjp

(I hope I didn't break too many other things, but I may have.)

I think it is better to have some tests with the standard datasets such as Japanese, IELex, Tujia, ObUgrian, Chinese to see that we achieve the accuracies in the same ballpark as in the arXiv paper.
