Factors in anaphora resolution: they are not the only things that matter
Ruslan Mitkov · 1997
The paper discusses the significance of factors in anaphora resolution and on the basis of a comparative study argues that what matters is not only a good set of reliable factors but also the strategy for their application. The objective of the study was to find out how well the same set of factors worked within two different computational strategies. To this end, we tuned two anaphora resolution approaches to use the same core set of factors. The first approach uses constraints to discount implausible candidates and then consults preferences to rank order the most likely candidate. The second employs only preferences and does not discard any candidate but assumes initially that the candidate examined is the antecedent; on the basis of uncertainty reasoning formula this hypothesis is either rejected or accepted.
