Dialogue structure as a preference in anaphora resolution systems

Comunicación presentada en ACIDCA 2000, International Conference on Artificial and Computational Intelligence For Decision, Control and Automation In Engineering and Industrial Applications, Monastir, Tunisia, 22-24 March 2000.

There are many works about anaphora resolution based on constraints and preferences to have successful results when they are applied to non-dialogue texts. However, these works lack consistency in the treatment of dialogues. In this paper, a dialogue structure proposal is presented in order to obtain information that will be included as a preference. This new constraint and preference system will achieve precision rates of 73.8% and 78.9% for pronominal and adjectival anaphora resolution respectively, improving the rates of 59.0% and 23.7% obtained without dialogue structure information.
