Applying Knowledge Map to Intelligent Agents in Problem Solving Systems

According to the four steps of problem solving proposed by Marshall in 1995, a knowledge structure is designed based on the Concept Map and the Concept Schema, which is so-called Knowledge Map. Knowledge Hierarchy derived from Hierarchy Map of Concept Map can be used to indicate the relationships among concepts, whereas Concept Schema represents the information of the corresponding concept. After the Knowledge Map is well analyzed and designed, three functions for manipulating knowledge in problem-solving systems, such as matching operation, locating operation and loading operation are considered. And finally an intelligent agent within Knowledge Map to accomplish problem-solving steps is implemented to providing assistances for students in distance learning environment.
