The question is in the title. Using Stanford's NLP coref module, I am wondering if a given word can be part of multiple coreference chains. Or can it only be part of one chain. Could you give me examples of when this might occur.
Similarly, can a word be part of multiple coreference mentions, or only one.
Thank you.
A word can be part of multiple coreference mentions. Consider for example the mention "the new acquisition by Microsoft". In this case, there are two candidates for mentions: the new acquisition by Microsoft and Microsoft.
From this example it also follows that a word can be part of multiple coreference chains.
