Family Outcomes in Early Intervention: A Framework for Program Evaluation and Efficacy Research
In this article we suggest eight questions that could serve as a framework for determining the extent to which early intervention has accomplished the goals inherent in a family-centered approach.

Dialog Act Modeling for Conversational Speech
We describe an integrated approach for statistical modeling of discourse structure for natural conversational speech. Our model is based on 42 `dialog acts', which were hand-labeled in 1155 conversations from…

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.
