San Diego, California-based Excalibur Technologies Corp has released RetrievalWare, a family of software products for building retrieval systems across databases and information systems. The tool includes most variants of Unix and Windows NT. It uses semantic expansion and network searching, combined with adaptive pattern recognition processing, which finds multiple data types via fault-tolerant fuzzy searching and automated indexing. The software development kit includes distributed client-server and application programming interfaces, graphical user interfaces delivered as source code, visual basic custom controls, and a relational database management system interface. These are the foundation for its applications, including client application programming interfaces, text and database retrieval, real-time and retrospective text searching, and an end-user system for intelligence analysis and document imaging. It also includes a Web server, and is priced from $12,500. The starter software development kit costs from $5,000, with additional systems from $2,500. Shipping will begin this month. Meanwhile, Excalibur will release the next generation of its Electronic Filing Software 4.0 late next year. Presently available as 3.65, it runs on Unix workstations and systems from Sun Microsystems Inc, IBM Corp, Digital Equipment Corp and HP-UX, Digital VMS and Alpha AXP/Open VMS.
