JFRED Chat Server

Sponsored by Institute of Mimetic Sciences, Inc.

An extensible java package for making directed conversation via text. Use JFRED to produce computer personalities like S.A.R.A.H. from EUREKA, on the SyFy Channel, or like HAL 9000 from the movie, 2001 A Space Odyssey. Your imagination is the limit.

JFRED was developed by Robby Garner and Paco Xander Nathan., with contributions by Søren Gjellerup Christiansen. The acronym "JFRED" refers to Java-based FRED Response Emulation Devices. The software platform developed around the deployment of Barry DeFacto, a personality built first as a C++ CGI program, but then re-designed as a Java web server, and eventually as a tiny applet. JFRED requires Java JDK 1.6 and is released as an Open Source project under the GNU Public License.

Overall, JFRED provides a natural language interface for Internet software that can be described as:

computer platform independent
multi-threaded server, as a Java servlet
fuzzy logic, rule-based AI
frames-based learning
language/dialect independent

The server supports a variety of front-end/client interfaces, including direct telnet, HTML/Servlet forms, Expect scripts, MOO bots, and Java applets embedded in HTML pages, as well as standard I/O for testing.
