... Hill, NJ 07974-0636 julia@research, att. com Abstract Interpreting fully natural speech is an important goal for spoken language understanding systems. However, while corpus studies have shown ... spontaneous speech pose serious prob- lems for spoken language systems.

We have shown that a KPCA-based model can significantly outperform state-of-the-art results from both na¨ıve Bayes as well as maximum entropy models, for supervised ... this, we describe a full model for WSD built on KPCA. We then discuss experimental re- sults confirming that this model outperforms state- of-the-art published models for Sensev...
