Examples of edu.stanford.nlp.dcoref.CorefChain

edu.stanford.nlp.dcoref.CorefChain
Output of (deterministic) coref system. Each CorefChain represents a set of mentions in the text which should all correspond to the same actual entity. There is a representative mention, which stores the best mention of an entity, and then there is a List of all mentions that are coreferent with that mention. The mentionMap maps from pairs of a sentence number and a head word index to a CorefMention. The chainID is an arbitrary integer for the chain number. @author Heeyoung Lee
