The Enhanced Frame Package is a tool to build Expert Systems. It is a frame based system, that initially was developed in C-Prolog by LaMora S. Hiss at Rochester Institute of Technology in 1987 for her master's thesis. It was enhanced in the current thsis to provide much larger expressive power andgreater ease of use. Several operators were modified/enhanced, and several new operators were added, while providing the user a balance of computational tractability, expressive power and consistency. Major concepts provided in the Enhanced Frame Package include - local consistency checking as opposed to global consistency checking and how the user can have the best of both options; the flexibility of loading a knowledge base file as a consistent system or as an inconsistent system; operations that work on working memory and operations that work on the original file in the working directory; the concept of a knowledge analyzer; the way one sees the human mind, knowledge and learning and its parallel in knowledge representation and the surrounding issues of consistency, expressive power and computational tractability.
