AN EVALUATION OF COREFERENCE RESOLUTION STRATEGIES FOR ACQUIRING ASSOCIATED INFORMATION

As part of our TIPSTER research program [Contract Number 94-F133200-000], we have developed a variety of strategies to resolve coreferences within a free text document. Coreference is typically defined to mean the identification of noun phrases that refer to the same object. This paper investigates a more general view of coreference in which our automatic system identifies not only coreferential phrases, but also phrases which additionally describe an object. Coreference has been found to be an important component of many applications.
