Entropy-based Pruning of Backoff Language Models
A criterion for pruning parameters from N-gram backoff language models is developed, based on the relative entropy between the original and the pruned model. It is shown that the relative…

Information extraction from HTML: application of a general machine learning approach
We show how information extraction can be cast as a standard machine learning problem, and argue for the suitability of relational learning in solving it.
