Abstract:

The objective of this effort was to provide support for the integration, enhancement, transition, and evaluation of component technologies produced from the Defense Advanced Research Projects Agencys DARPA Intelligent Integration of Information 13, Intelligent Collaboration and Visualization ICV, and Information Management IM programs. This effort investigated and developed techniques to extend the capabilities of SIMS to integrate data that is incorrect, inconsistent, andor missing. The SIMS approach was extended to deal with HTML documents accessible through the HTTP protocol. Data mining techniques were used to create automated and semi-automated modeling facilities. A facility for searching for patterns present in data and in the database structure of new sources was created. Overall, this effort has made the integration of multiple, distributed, inconsistent information sources a practical reality and easily portable at reasonable cost.
