Autonomy Delivers New Innovations Across Meaning Based Marketing Platform

Autonomy Reshapes Marketing Landscape with New Analytics Visualization, Self-Service, and Multichannel Optimization Solutions

CAMBRIDGE, England and SAN FRANCISCO, March 3, 2010 - Autonomy Corporation plc (LSE: AU. or AU.L), a global leader in
infrastructure software for the enterprise, today announced significant
innovations across the company's Meaning Based Marketing platform - allowing
businesses to understand, act on, and optimize all forms of information.
Based on Autonomy's ability to automatically identify concepts in structured
and unstructured information, Autonomy's Meaning Based Marketing platform is
uniquely enabled to handle the scale, complexity, and speed required to
succeed in the modern era. As a result, marketers are increasingly turning to
Autonomy's end-to-end marketing platform as an engine to engage customers,
capitalize on emerging opportunities, and drive growth and profits for their
businesses.

"As host of CMO CLUB dinners around the world, I hear from Chief
Marketing Officers every day about how their job is becoming more and more
difficult," said Pete Krainik, Founder, The CMO CLUB. "They are overwhelmed
with the exponential growth of new forms of information - especially social
networks and video - and how to bring all this data together to move quickly
on business opportunities and protect their brand. I'm hearing lots of
excitement from club members about Autonomy's Meaning Based Marketing
platform for allowing marketers to see what is really happening inside and
outside their business, act quickly on the information, and deliver the
revenue and customer engagement results they need."

Marketers today enjoy thrilling new opportunities - as well as
significant risks. A new world has opened up for marketers - in the form of
social media, video, and blogs - however businesses still struggle to
identify the useful information amidst the ocean of data generated in these
networks every day. Businesses have invested billions in CRM, business
intelligence, contact center, demographic, and campaign management systems,
but find it challenging to link data between these legacy systems and social
networks in order to act on new opportunities or risks to their business. A
small amount of chatter about a company's product today can yield a sales
bonanza if recognized and acted on quickly, and likewise can turn into a
major reputation hit if overlooked and unmanaged.

Autonomy's Meaning Based Marketing platform is built for the
next-generation of marketers looking to understand, act on, and optimize all
forms of information - linking together internal systems with external data
in order to deliver the most compelling and targeted data to customers across
every channel. Autonomy has delivered several significant innovations,
including new self-service modules, across every part of the company's
integrated, comprehensive platform.

Automatically Understand All Forms of Customer Information

At the core of Autonomy's Meaning Based Marketing platform is the
Intelligent Data Operating Layer (IDOL) which allows businesses to
automatically detect, analyze, and act on concepts, allowing computers to see
patterns in information the way people do. This unique technology is based on
hundreds of patents and powers a wide range of applications with over 20,000
customers around the world.

Autonomy has delivered a new console, called Explore, which provides
marketers with a visualization interface to Autonomy IDOL's deep analytics
capabilities. Autonomy Explore provides marketers with the following:

    - A new analytics visualization console, which connects to
      every customer touchpoint, including social networks, contact centers,
      and the web.
    - Discovers patterns, trends, and sentiment across all channels
      inside and outside an enterprise.
    - Includes out of the box widgets for automatically categorizing
      and understanding market trends and clusters of customers.

Automatically Act on Insights to Win Market Share and Manage Reputation

Autonomy provides the most comprehensive platform for allowing marketers
to automatically act on the insight obtained from all customer touchpoints,
whenever and wherever interactions take place. This includes information from
internal systems, like corporate websites, as well as external sources like
social media networks. Autonomy has added significant enhancements to the
company's web content management, rich media management, and contact center
solutions.

      includes new desktop tools to allow seamless integration with Microsoft
      Office.
    - Interwoven LiveSite - industry-first agnostic content delivery
      capabilities which allow marketers to dynamically display content to

      Autonomy's full spectrum of capabilities, including explicit and

      includes new capabilities that automatically tag and classify any image
      or video, regardless of format or language. This allows marketers to
      more quickly and easily find the right image through a new rich media
      interface, allowing them to deliver more accurate, relevant, and
      brand-consistent content to customers.

    Autonomy etalk Contact Center Solutions
    - etalk Qfiniti - provides active "listening" across all
      customer interactions - including contact center, website, email,
      in-store, and social media. Autonomy etalk's Qfiniti platform for the
      contact center provides the most advanced speech analytics of
      enterprise voice and chat interactions. Autonomy's IDOL platform
      provides intelligent connectors to all forms of data - including
      unstructured - to bring back analysis that can be leveraged across an
      organization.

Automatically Optimize Customer Interactions Across All Customer
Touchpoints

Autonomy's Multichannel Optimization solution combines meaning-based
technology with Autonomy Optimost's multivariate testing technology to ensure
businesses deliver the most compelling combination targeted content to
customers across all channels.

    - Autonomy has added an intuitive self-service console to its
      Optimost offering, allowing customers to choose between managed service
      offerings as well as self-service. The new user interface includes a
      marketing dashboard, as well as a new experiment authoring process.
    - Now customers can more easily test and optimize content between
      customer touchpoints. For instance, a marketer managing a potentially
      damaging product recall can seamlessly test the most effective message
      and content across the company's contact center, web, and in-store
      channels.
    - Optimost Adaptive Targeting provides new analytics capabilities
      to mine all major types of customer attributes to create customer
      segments, including context (how the visitor arrives at the Website,
      e.g. search keyword), geography, time of day, and demographic,
      behavior, and account profile information. Once customer segments are
      created, multivariate tests are conducted on an unlimited number of
      copy ideas, offers, and layouts to determine the best solution for each
      audience segment.
