Corpora: Anaphora resolution

[Narjès Boufaden]

I understand what you said about the problem of  circularity, but I think that in
a dialog between persons usually we do not find long distance reference because of
the limit of our short term memory. We can't keep long context in mind. May be
theoretically the problem would exist but practically, I do not think.

Thanks for your input.

Narjès.
