nlp function does'nt work

[mmt1402]

Hi,
At corpus_construction/mlm_corpus/corpus_construction.py line 46 a function named "nlp" has been used to filter instances where "so" indicator does'nt indicate logical reasoning (like so happy), but it never defined before and make error in producing results.
