- C. Rosé, Yan Qu. 1995. Automatically learning to use discourse informa-tion for disambiguation. Abstract: In this paper we discuss how we apply predictions from our plan-based discourse processor discussed in (Rosé et al., 1995) to the problem of disambiguation. The work we report here has been done in the context of the Enthusiast Spanish to English translation system. The Enthusiast system is part of the JANUS Speech-to-Speech translation system (Woszcyna et al., 1993; Woszcyna et al., 1994; Suhm et al., 1994; Levin et al., 1995). We discuss and evaluate two different methods for combining context based predictions with non context based predictions, namely a genetic programming approach and a neural network approach. We demonstrate the advantage of incorporating context-based predictions over the purely non context-based approach discussed in (Lavie, 1995). The results presented here show a significant improvement over our previous results reported in (Levin et al., 1995).
