Objective

Introduction to knowledge engineering and training in project management skills.


Description

This course introduces students to advanced topics on knowledge engineering. Students are exposed to and learn to practice advanced knowledge engineering techniques that have evolved from past expert system projects. They are also given the opportunity to demonstrate their understanding of knowledge engineering by building and documenting an expert system that addresses a real-world problem. The course prepares the students for graduate research in the area of expert systems.

Project Management Skills This course also has the special feature of preparing students to meet the many administrative challenges faced by a new engineer entering their first job. While the series of engineering courses offered by most universities prepare students to meet technical challenges, they typically fall short on the administrative side. Specifically, this course teaches students how to:

The first half of the course is conducted in class through conventional lectures. During the second half students work on their project. They contact a representative from a local company to identify a problem where expert system technology may help, and obtain cooperation from the firm to participate in the project. They then combine the technical and management skills learned in the course to deliver to the firm the finished expert system. They also meet weekly with the instructor of the course to assure the project's progress.
