Knowledge Representation and Multiple Criteria Aggregation

This chapter returns to the issues of knowledge acquisition for creativity support addressed in Chap. 4, this time from a more theoretical, mathematical perspective. The chapter is organised as follows. In these introductory remarks, we discuss diverse types of knowledge and the need for knowledge representation; then we turn to a discussion of formal models of knowledge representation. Then several meanings of the concept of knowledge integration are presented, distinguishing expert-based intuitive integration from computer-based automatic integration. Examples of existing approaches to the integration of knowledge are given. In particular, multiple criteria approaches to knowledge acquisition and integration, including new trends and solutions, are presented.
