To get a TER score, both hypothesis sentence and reference sentence have to a list of word.

>>> ref = u'SAUDI ARABIA denied THIS WEEK information published in the AMERICAN new york times'.split()
>>> hyp = u'THIS WEEK THE SAUDIS denied information published in the new york times'.split()
>>> '%.3f' % pyter.ter(hyp, ref)
'0.308'

If you want to use a character based matching, write a code like that.

>>> ref = list(u"Pythonは、より素早く、効果的にシステムとの統合が可能なプログラミング言語です。")
>>> hyp = list(u"Pythonは、より迅速に動作するとより効果的にシステムを統合できるプログラミング言語です。")
>>> '%.3f' % pyter.ter(hyp, ref)
'0.357'
