Dr David A. Evans is President, CEO, and Chief Scientist of
Clairvoyance Corporation, which he founded (as CLARITECH Corporation)
in 1992. He also serves as the Chief Scientist
and Director, Advanced Technology Innovation, for Justsystem Corporation
of Japan.
David received his PhD degree in Computational Linguistics
from Stanford University in 1982. He joined the faculty of Carnegie
Mellon University in 1983, where he established the
Computational Linguistics Program (in 1985) and the Laboratory
for Computational Linguistics (in 1986), both of which he directed
until 1996. As a Professor with appointments in the Department
of Philosophy and in the School of Computer Science, he brought
an interdisciplinary perspective to his work in natural-language
processing (NLP) and information science. His development of the
CLARIT system, beginning in 1988, realised a fusion of such ideas.The
resulting CLARIT technology pioneered the use of language analysis
to support such diverse functions as
automatic text indexing, retrieval, filtering, categorisation,
summarisation, extraction and information organisation -- all
within a single core process.
Today the CLARIT system is the core technology in Justsystem's ConceptBase, a suite of applications that together represent more than 60% of the market share of knowledge-management products in Japan. ConceptBase Search received the "Software Product of the Year" Award from the Japanese Government in 1998.
David has been awarded, to date, 15 US patents on techniques and algorithms related to information processing. He is a Fellow of the American Association for the Advancement of Science (AAAS) and of the American College of Medical Informatics (ACMI).
David regards his current work, focusing on Text Mining and
Causal Modelling, as the key functionality needed for automated
Decision Support -- the ultimate challenge for information processing.
