CAMBRIDGE, England and SAN FRANCISCO, December 6, 2010 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that Autonomy
Meaning Based Healthcare (MBH) received the prestigious 2010 Healthcare IT
Summit Innovation Award for "Solution With Greatest Market Potential."
Autonomy was selected for this award by attendees at the 2010 Healthcare IT
Summit, including leading healthcare delivery organizations and insurance
providers such as Massachusetts General Hospital, University of Pennsylvania
Health System, Johns Hopkins Healthcare, UnitedHealth Group, and CIGNA. The
prestigious accolade mirrors the outstanding response Meaning Based
Healthcare has garnered from customers, analysts, and the press, increasing
market momentum for Autonomy's transformative healthcare technologies.

"The opportunity to automate this industry is staggering," said Sue
Feldman, Research Vice President at IDC. "The U.S. alone spends 16.4% of its
GDP on healthcare, and even so is unable to connect the dots between
research, patient records, clinical studies, and practice guidelines …
Auminence promises to make real-time diagnosis recommendations by detecting
patterns in information from multiple sources and then producing suggested
best matches for the patient."
