Gister: An Evidential Reasoning System SRI pioneered evidential reasoning for drawing conclusions from multiple sources of evidential information about dynamic real-world situations. We have developed formal foundations for reasoning under uncertainty covering both probabilistic models (i.e., Bayesian and Dempster-Shafer) and possibilistic models (i.e., propositional logic and fuzzy logic) and have incorporated all of these techniques into a single uncertain reasoning tool, Gister.

Grasper: An Interactive Network Editor and Graphical Database Grasper is a system for viewing and manipulating graph-structured information, and for building graph-based user interfaces for application programs.
