Our work focuses on two;related areas: (1) the design of user-trained systems that can efficiently and reliably;extract the important information from a document, and (2) the machine learning of natural;language.;Information Extraction.;As part of Cornell's CSTR project, we are using information extraction techniques to;support content-based browsing of technical texts.;The Kenmore Project.;The focus of the Kenmore project is on developing techniques to automate the knowledge;acquisition tasks that comprise the building of any NLP system. Very generally, Kenmore;acquires linguistic knowledge using a combination of symbolic machine learning;techniques and robust sentence analysis. It has been used with corpora from two;real-world domains to perform part-of-speech tagging, semantic feature tagging, and;concept activation and to find the antecedents of relative pronouns. In current work,;we are extending Kenmore to handle larger text corpora and additional disambiguation;tasks. In all of our work, we evaluate the language learning;components in the context of the larger NLP application in which it is;embedded. The goal of the project is to determine the conditions under which machine;learning techniques can be expected to offer a cost-effective approach to knowledge;acquisition for NLP systems.;Teaching;CS674 Natural Language Understanding, Spring 1996;Foundations of Artificial Intelligence (CS472) and Practicum in;Artificial Intelligence (CS473), Fall 1996;Seminar in Natural Language Understanding;Selected Publications;Automating Feature Set Selection for Case-Based Learning of; Linguistic Knowledge,C.
