Autonomy Extends Market-Leading Social Media Capabilities to eDiscovery

Only Autonomy Delivers Comprehensive Suite for Social Media that Spans Sentiment Analysis, Compliance, and eDiscovery

NEW YORK, January 31, 2011 - LegalTech — Autonomy Corporation plc (LSE: AU. or AU.L), a global leader
in infrastructure software for the enterprise, today announced new
capabilities for identifying, preserving, and collecting social media for
eDiscovery. These capabilities are a component of Autonomy's end-to-end
eDiscovery solution, and builds on the company's comprehensive set of
offerings for social media, which span marketing, compliance, and eDiscovery
solutions. Powered by Autonomy's unique ability to understand sentiment,
patterns, and concepts in all forms of data, the new EDD capabilities allow
businesses to incorporate social media and rich media into their EDD
processes.

Businesses today are rapidly increasing investment in social media,
building out teams and programs designed to engage with customers and promote
their organization through social sites. At the same time, new requirements
in several countries - such as the Federal Rules of Civil Procedure (FRCP) in
the United States and the Civil Procedure Rules (CPR) in the United Kingdom -
state that information on social media sites is now discoverable. Likewise,
FINRA (The Financial Industry Regulatory Authority) recently issued FINRA
Regulatory Notice 10-06, which requires member firms to supervise and archive
content posted to social media for business purposes. This means social media
data must be managed in the same manner as all other enterprise data sources,
and legal teams must be prepared to search for, identify, preserve, and
collect this form of information.

Autonomy provides businesses with the industry's most comprehensive
solution for social media, allowing organizations to drive successful social
marketing programs, maintain compliance, and prepare social data for the
eDiscovery process:

    -- Autonomy Explore - identifies, analyzes, and acts on patterns across
       all customer touchpoints including websites, mobile phones, contact
       centers, and social media data. By automatically understanding
       customer sentiment across all channels, businesses can overcome
       barriers created by disparate systems, point solutions, and
       organizational structures in order to increase revenue.
    -- Autonomy Social Media Governance - allows businesses to proactively
       prepare for compliance and litigation around social media. The product
       is an extension of Autonomy's market-leading supervision, policy, and
       compliance platform - used today by the world's leading corporations.
    -- Social Media EDD - allows businesses to rapidly respond to any
       litigation in which social media is relevant, by intelligently
       searching, identifying, preserving, and collecting internal and
       external social media interactions. These capabilities are part of
       Autonomy's end-to-end eDiscovery offering, which allows organizations
       to manage their entire eDiscovery process from a single,
       market-leading platform.
    -- Social Media Connectors - Autonomy provides connectors into thousands
       of relevant news feeds, blogs, and social media sites like Facebook,
       Twitter, and YouTube. Additionally, Autonomy provides connectors to
       other customer-facing and internal systems - including call center,
       audio, customer relationship management software - to provide
       marketers and legal teams with a comprehensive and holistic
       understanding of a particular subject area.

Finding Meaning in Social Media

Social media presents unique challenges to organizations relying on
traditional keyword spotting technologies to identify sentiment and concepts
in social networks. Social media by nature is conversational, and filled with
jargon, slang, varying emotional undertones (e.g. sarcasm, excitement,
disappointment) and stated so briefly that context is difficult to discern.
For instance, an organization facing a product liability lawsuit would have a
difficult time using keyword tools to recognize negative sentiment in an
employee or customer tweet that said "this new product is a dog."

"Autonomy has over a decade of experience in providing advanced
technology to the world's leading government intelligence organizations to
help them decipher the meaning of messages for homeland security, and this
same technology is now being used to govern and conduct discovery on social
media," said Mike Sullivan, CEO of Autonomy Protect. "Our work with
intelligence agencies has been a great proving ground, as those
communications are often short, cryptic bursts, similar to social media,
which only our meaning-based technology can understand. Just as we have
incorporated audio, video, email, and other data types into our eDiscovery
offering, we are now adding social media as another data type that we can
process."

Autonomy's Social Media for EDD includes the following capabilities:

    -- Intelligently search, identify, preserve, and collect internal and
       external social media interactions
    -- Integrate social media discovery with Autonomy's leading eDiscovery
       and information governance platform
    -- Create proactive policies for real-time monitoring and discovery to
       enforce information risk policies
    -- Preserve and collect social media subject to legal hold
    -- Meaning Based Computing technology automatically understands and draws
       connections in a range of data types including video, audio, email,
       instant messenger, and social media, giving businesses a complete
       picture
