'X-' prefix is prepending to POS(Part of Speech) tag of inside morphs for distinguishing following morphs.
-
we can evaluate the predicted result morph-by-morph or eojeol by eojeol manner(every lines having 'X-' POS tag are removed).

* note that F1 score from the 'seqeval' package for 'max_seq_len=50' might be similar with that for 'max_seq_len=180'.
however, the final evaluation using 'conlleval.pl' should be different.
for example, with n_ctx=50.
the F1 score from 'seqeval' is 0.8602.
the F1 score from 'conlleval.pl is 0.8438.

this is due to the test.txt data has longer sequences than the 'n_ctx' size.
therefore, the evaluation results using 'seqeval' are not the final F1 score.
we recommend to use 'conlleval.pl' script for NER results.
