ROCK Knowledge Base Viewer

Senior Project: 1992-1993

As knowledge base (KB) systems become large and complex, it becomes more imperative to have a graphical interface to describe them. Complex paths through the KB hierarchy, dynamically created relationships, and complex inheritance require run-time graphical facilities. The goal of this project was to create a knowledge base viewer for ROCK, a frame system that supports a semantic data model, providing a number of knowledge representation capabilities. These capabilities include attribute, message, and relation slots on frames, user-defined inheritance over relations, demons, hypothetical reasoning, annotations, dynamic slot and class creation and deletion, and browsing functions for inspecting a ROCK knowledge base. The interface was developed as a C++ library callable within an application, started with a frame to view and inspect. It allows a view of the KB as a directed cyclic graph with system-defined and user-defined relations being displayed. In addition, a frame may be inspected with its slots, slot values, and their source. Slot control frames (frames describing slots) may also be inspected as well as meta-knowledge (annotation information).
