MetaCarta Joins Convera’s Open Excalibur Partner Program

Cambridge, MA - March 20, 2006 - MetaCarta®, Inc., a leading provider of geographic intelligence solutions, announced today it has joined Convera Corporation’s (NASDAQ: CNVR), Open Excalibur™ Partner Program enhancing Excalibur’s ability to solve advanced Internet search challenges. MetaCarta’s geographic search capabilities will allow Excalibur users to rapidly sift through and find relevant unstructured data using geographic text references inherent in that information.

MetaCarta’s technology automatically identifies geographic references using advanced natural language processing (NLP) from unstructured content in a customer’s archives, including email, web pages, newswires and cables. It then assigns a latitude and longitude to these references so that users can analyze their text archives using geographic maps, keywords and time as filters.

“Convera is building an open platform for mining the Internet,” said Patrick Condo, CEO of Convera. “We provide the basic infrastructure and the index/search/retrieval function on which other key technologies can be layered to solve customers’ problems.”

The Open Excalibur™ search platform provides easy integration of the 3rd party products and services by adhering to established open interface standards such as REST and XML. In addition, Convera is working with partners on an open indexing API to allow 3rd party technologies such as language processing, entity extractors, and geo-tagging to fit directly into the indexing pipeline. The Open ExcaliburTM platform will allow customers to incorporate other best-of-breed technologies to customize the Excalibur search and analysis capabilities to their specific needs.

“MetaCarta’s unique technology has already proven essential to government and commercial enterprises. MetaCarta’s solution complements Excalibur and together provides a robust solution for these communities,” said Claudine Bianchi, Vice President of Marketing at MetaCarta.
