May 17, 1995



The Department of Defense's Advanced Research Projects Agency (ARPA) today released Version 1.5 of the TIPSTER software Architecture Design Document. The architecture defines interfaces for information retrieval and extraction components so that they can be more easily deployed together, share common functional modules, and share common knowledge bases. TIPSTER sponsors software to permit computers to review large amounts of text and select items of interest.

The ARPA TIPSTER Text program, started in 1991, supports research to improve informational retrieval and extraction software and works to deploy these improved technologies to government users. This technology is of particular interest to defense and intelligence analysts who must review increasingly large amounts of text.

The use of the TIPSTER software architecture version released today will help control the costs of deploying and upgrading text handling information systems for the government. In addition, it will promote further research in text handling information technologies by providing a means for researchers to share software and knowledge bases. The TIPSTER systems engineer will keep a record of conformance to the TIPSTER architecture of applications and products for interested users.

This is the latest phase of the TIPSTER program. From 1991 to 1994, the program improved information retrieval and extraction software algorithms for accuracy and portability across multiple human languages and subject areas.

In the last year, the program has sponsored the development of the software architecture, which is the joint work of a number of leading research organizations: BBN Systems and Technologies, Cambridge, Mass.; Center for Intelligent Information Retrieval, University of Massachusetts, Amherst, Mass.; Computing Research Laboratory, New Mexico State University, Las Cruces, N.M.; Courant Institute of Mathematics, New York University, New York, New York; HNC Software, San Diego, Calif.; Management and Data Systems of Martin Marietta, Philadelphia, Penn.; SRI International, Menlo Park, Calif.; TRW, Redondo Beach, Calif.

While the architecture will be undergoing revision over the next year, it is being used as the basis for a number of pilot intelligence correlation applications. An up-to-date version of the Architecture Design Document is available via Internet at the following URL:
