Ellen Voorhees, leader of the text retrieval group in the Information Technology Laboratory at the National Institute of Standards and Technology (NIST), was recently recognized as a “Distinguished Scientist” by the Association for Computing Machinery (ACM) for establishing “key components of information retrieval evaluation methodology through individual research and directing international evaluation projects.”

Voorhees has been a leading figure in organizing NIST’s annual Text Retrieval Conference (TREC), which fosters research in information retrieval by creating the infrastructure required to do large-scale testing of retrieval technology. Information retrieval or search methodologies help find content that is not specially structured for computers. The technology is a key component of diverse applications including e-commerce, legal discovery, intelligence gathering, and scientific research, as well as Web search.
