China's Civil Aviation Administration Selects Autonomy's Meaning Based Computing Platform for Its Digital Library

Autonomy IDOL Provides Users With Quick and Easy Access to More Than Ten Million Documents

CAMBRIDGE, England and SAN FRANCISCO, February 16 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced that the Civil
Aviation Administration of China (CAAC) has selected Autonomy's Meaning Based
Computing platform, IDOL, to manage and access more than 10 million documents
in its digital library. The Autonomy solution will enable the CAAC's digital
library, which is a Chinese Ministry-owned branch of the Chinese National
Library, to integrate all of its content sources and provide its users with
fast and accurate information access.

With the rapid development of the Chinese aviation industry, the CAAC has
seen a dramatic increase in the number of documents in its digital library.
As a result, the CAAC recognized the need to implement a sophisticated
information access solution that can deliver scalability and high-speed
access to its millions of documents. Autonomy IDOL will allow the CAAC to
integrate all of its different data types from various content repositories
within the CAAC Digital Library, and provide advanced functionalities,
including conceptual search, classification, clustering, and document
recommendations.

Autonomy IDOL performs conceptual and contextual analysis and probability
matching on information to find the meaning within and the
inter-relationships between and among disparate pieces of content. This
unique approach allows global organizations to find and access the most
pertinent content for business value or risk management, irrespective of
languages, operating systems, and file types. By supporting more than 1,000
different data formats, including structured, semi-structured, and
unstructured data, located across 400 different content repositories,
Autonomy can search all categories of information repositories in an
organization. IDOL is fault-tolerant using load balancing and mirroring,
highly scalable, secure, and has sub-second performance on billions of files.

According to Shenghui Zhang, director at the Center of Aviation Safety
Technology, "One of the CAAC's objectives is to promote safety management in
the aviation industry. The Autonomy IDOL solution will provide our users with
easier access to mission-critical information in our digital library, while
delivering a solid foundation for the CAAC's business growth and
development."

"With the dramatic growth in China's aviation industry, it is critical
that users are able to not just find the right information to do their job,
but it is equally important for them to share their knowledge and expertise
in the field," said Mike Lynch, CEO of Autonomy. "We are delighted that
Autonomy will become a key partner to the CAAC in its effort to improve
information sharing amongst its users."
