Thank you for your attention.

I haven't tried to set the tagging_schema as OT and the empty list here (i.e., line 118) is actually a placeholder.

If you still want to run the code with OT tagging schema, you can change this line to:

return ['O', 'EQ', 'T-POS', 'T-NEG', 'T-NEU']

BTW, after changing the value of tagging_schema, you should remove the cached data files so that the newly built ones follow the updated tagging schema.
