David Andreoff Evans (born 1948 in St. Louis) is a scientist in the field of computational linguistics, best known for his research into indexing using natural language processing, and in ontology learning, especially in medical informatics.

Life[edit]

Evans attended Stanford University, receiving his Ph.D. in Computational Linguistics there in 1982. He attended the Inter-University Center for Japanese Language Studies in 1979.[1] He was on the faculty of Carnegie Mellon University from 1983 until 1996, and founded their Computational Linguistics Program and Laboratory for Computational Linguistics in 1986. Supported by a grant from Digital Equipment Corporation, he led a research project on "computational-linguistic approaches to indexing and retrieval of text" (CLARIT).[2] In September 1992, CLARIT was spun-out from Carnegie-Mellon as a company called Claritech. The technology was used to index the papers of politician H. John Heinz III.[3][4] Claritech became a research and development subsidiary of JustSystems and its name was changed to Clairvoyance Corporation in 1996, before becoming JustSystems Evans Research in 2007. [5]

He has made many contributions to the field of computational linguistics and information retrieval,[6] authoring books, many research papers, and is the holder of 25 US patents.[1]

Evans was elected a Fellow of the American College of Medical Informatics in 1999.[7]
