I have extracted data from a corpus that collected sentences with an antecedent and a next sentence with a pronoun or a stressed pronoun in subject position. Now, the anaphora can either refer back to a subject or an object antecedent.
"Mary passes the book to Sally. She starts reading it." (She can corefer both to Mary (suj) or Sally (obj)
How can I measure if the cooccurrence of, say, pronoun - subject antecedent is significant?
Do you have any suggestions?
I also thought of making count, normalizing the result and compare the means (subject mean vs object mean). Comparing z-scores would be the adequat thing here, correct? But, how do I get the standard deviation?
