AUTONOMY SUPPORTS NTT DOCOMO I-MODE WIRELESS PROTOCOL.

Autonomy Corporation plc (Nasdaq: AUTN; LSE: AU.; Easdaq: AUTN), San Francisco, a global leader in infrastructure software for the Web and the enterprise, has announced the expansion of its technology for wireless-enabling applications with support for NTT DoCoMo i-mode wireless protocol. This new support complements Autonomy's i-WAP(TM) software, which was first introduced in February 2000.

According to Autonomy CEO Michael Lynch, wireless adoption is occurring at different rates throughout the world and Autonomy is well positioned to respond to the evolving market. "Autonomy's strategic reseller partners are located throughout the world and our language-independent technology now supports the two predominant wireless protocols: wireless application protocol (WAP) and NTT DoCoMo i-mode," said Lynch. "In Asia, we are working with NTT Software. In Europe, our iWAP technology is already utilized by customers, such as Ericsson. Regardless of which protocol North America embraces, we will support it."

Wireless devices require highly targeted, personalized content. The majority of this content is in the form of unstructured information, i.e. Web pages, e-mails, news articles, Word documents. Autonomy's technology seamlessly extends applications that utilize unstructured information into the wireless world. With Autonomy's technology, content and service providers, enterprises and commerce vendors can automate the tagging, categorizing, linking, delivery and personalization of unstructured information within their own wireless applications.

Lynch commented that Autonomy's technology enables customers to overcome the two biggest problems mobile users face today: bandwidth and usability. "Modem speeds, screen size and restricted input and navigation tools of current mobile devices severely limit the amount of content a user can permit to cross his or her screen," said Lynch. "As a result, content must be highly personalized. Our software delivers highly relevant information at the right time, enabling users to work more efficiently on the move."

Autonomy's technology features automated content aggregation and hypertext linking between related content. It offers automatic user profiling to deliver personalized content via alerts and customized news pages. Autonomy's technology enables the delivery of the relevant information in real-time, either in full text or as an automatically generated summary. The result is that users do not waste valuable time browsing the web or sifting through large amounts of irrelevant information on their mobile phones or handheld devices.

Among the European companies already deploying Autonomy's i-WAP to automate the delivery and personalization of timely and relevant content for their mobile users are Ericsson and Yatack. Ericsson, a world-leading supplier in the telecommunications and data communications industry, utilizes Autonomy's technology to automatically deliver relevant business information directly to employees through their mobile phones, handheld devices or straight to their desktop. Yatack, Scandanavia's most advanced consumer shopping service, uses Autonomy's technology to provide an auction service whereby site users can bid in real-time and be automatically alerted to new items or special offers via WAP transmissions sent to their mobile phones and handheld devices.

Availability

Autonomy' i-WAP and module for NTT DoCoMo i-mode are available for Microsoft Windows NT, Windows 2000, Linux, Sun Solaris and most versions of UNIX. The two products aggregate content in HTML, XML, text files and WML. i-WAP is currently available in Europe and will be available in North America in January 2001. The module for NTT DoCoMo i-mode is expected to be available worldwide in the first quarter of 2001.
