Install
We assume that you are running the Anaconda Python distribution.
Type the following in your terminal and you should be good to go!
$ make
$ make install
$ make test
To grab some POS tagging data run, e.g., English UD data,
$ make data/UD/English
Here is an example invocation for training a model
$ python vocrf/pos/tagfail.py --tag-type upos --lang English \
--C .01 --budget 1500 \
--inner-iterations 1 --outer-iterations 2 \
--initial-order 0 --max-order 0 --context-count 5 \
--dump /tmp/foo
(To quickly test the model on some real data, pass in the --quick flag, which
will run on a small subset of data.)
