"""
|
||
|
|
Get a mapping of (lemma, sense_number)-->supersense, and a mapping
|
||
|
|
(lemma, ON group)-->(lemma, sense_number).
|
||
|
|
|
||
|
|
Then we can read the OntoNotes token-->(lemma, ON group) annotations, and resolve
|
||
|
|
them to the token-->supersense annotations we want to train from.
|
||
|
|
|
||
|
|
supersense: A WordNet lexical file number
|
||
|
|
sense_number: A WordNet sense key, found in e.g. wordnet/index.sense file
|
||
|
|
lex_filenum: A WordNet "super sense", or lexical file number.
|
||
|
|
onto_group: An OntoNotes sense grouping, which dominates zero or more WN senses.
