Louise Guthrie has undertaken research in Natural Language Processing since completing her Ph.D. in computer science in 1986. Her early work focused on the areas of information extraction, computational lexicography, and word sense disambiguation. Recent research has been on text classification, semantic analysis of text, document reliability and security.
She began her career in Mathematics, and became interested in Computer Science while developing one of the first commercial packages for stock market analysis. She was a researcher and Associate Director of the Computing Research Laboratory, New Mexico State University, where she participated as part of the team funded by the DARPA Tipster program to develop text extraction systems and participate in the MUC (Message Understanding Conferences) competitions. Subsequently, she became the Lead Scientist in Text processing for Lockheed Martin (formerly GE Aerospace), where she managed the development of one of the top performing text extraction systems.
As a member of academic staff at the University of Sheffield for the past nine years, she has been partly or fully responsible for a large number of funded research projects, and in 2003, her project was chosen for the Summer Workshop at Johns Hopkins University Center for Language and Speech Processing.
Her recent research has been on technology to discover hidden meanings in text.
