Method Detail

match

int match(Mention mention,
          MentionChain chain)

Returns the match score between a specified mention and mention chain. Normal return values are positive integers between 0 and MAX_SEMANTIC_SCORE inclusive. A return value of NO_MATCH_SCORE, which is guaranteed to be negative, indicates that the mention cannot be matched to the mention chain.

chain - Mention chain to match.

Returns:

Match score between mention and mention chain.
