Senior Project - NOMOSS

As knowledge base systems become large and complex, it becomes more imperative to have a graphical interface to view and manipulate them. Complex paths through the knowledge base hierarchy, dynamically created relationships, and complex inheritance require run-time graphical facilities. The goal of this project was to create a knowledge base editor 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 possibly modify. It allows a view of the knowledge base 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. These relations and frames may be modified and saved to the knowledge base.
