David A Evans

JustSystems Evans Research, USA

President, CEO, and Chief Scientist of JustSystems Evans Research, Inc. (formerly Clairvoyance Corporation, which he founded in 1992). He also serves as the Chief Scientist and Director, Advanced Technology Innovation, for JustSystems Corporation of Japan. David received his Ph.D. degree in Linguistics (specializing in Computational Linguistics) from Stanford University in 1982. He was a post-doctoral fellow with the Meaning and Cognition Group at the Center for Advanced Study in the Behavioral Science (1982) and in Cognitive Science at the University of California, Berkeley (1982-83). He joined the faculty of Carnegie Mellon University in 1983, where he served as a Professor in the Departments of Philosophy and Computer Science, and where he established the Computational Linguistics Program (in 1985) and the Laboratory for Computational Linguistics (in 1986), both of which he directed until 1996.

In 1988, David commenced development of the CLARIT system, which pioneered the use of NLP-based language analysis to support such diverse functions as automatic text indexing, retrieval, filtering, categorization, summarization, extraction, and information organization -- all within a single process. Today the CLARIT is the core technology in JustSystems's ConceptBase suite of applications, which command a significant portion of the total knowledge-management market in Japan. One component of the technology, ConceptBase Search, received the Japanese government's "Software Product of the Year" award in 1998.

David has published three books and produced more than two hundred articles and other technical reports. He has been awarded, to date, 24 U.S. patents on techniques and algorithms related to information-management and text-mining technology, mono-linguistic and cross-language information retrieval, clustering, filtering, semantics, and interface design, with more than a dozen additional applications pending. He is a Fellow of the American Association for the Advancement of Science (AAAS), the American College of Medical Informatics (ACMI), and the Association for Psychological Science (APS).
