The PROC package contains the C-code and data for training and testing the story processing modules of the DISCERN system. PROC is trained to read and paraphrase script-based stories and answer questions about them. It includes a "real-time" X11(R5) graphics display for visualization and debugging and routines for collecting performance statistics throughout training and testing. For more details, see the Subsymbolic NLP book , or a (slightly old) PROC paper. Even though PROC was developed as part of DISCERN, it itself can serve as a starting point for various experiments in modular connectionist NLP architectures. It includes code for sequential input and sequential output SRN as well as nonrecurrent backpropagation networks, the FGREP mechanism for developing distributed representations for words, and for cloning words with the content ID technique. There are also general routines for managing the simulation, collecting performance statistics, and visualizing the networks "real-time" on an X11 graphics display.
