Knowledge is commonly socially constructed, through collaborative efforts towards shared objectives or by dialogues and challenges brought about by different persons' perspectives.

Mitta, Deborah, Ellis, Newton C. and Simmons, Dick B. (1990): Human Factors Data: Knowledge Sources for Intelligent Design Associates. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 308-311.

A number of human factors data sources provide guidelines and recommendations for the system design process. Much of this information is available to the human factors engineer in design handbooks, textbooks, and periodicals. This paper will discuss the feasibility of incorporating human factors design data into intelligent, knowledge based systems referred to as design associates. Results of recent efforts to implement two types of design associates are also discussed.

Simmons, Dick B. and Escamilla, Terry D. (1989): The Mechanics of Representing Knowledge. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 361-365.

This paper describes mechanical knowledge representation schemes found in several popular expert system building tools (ESBTs). In order to realize the full potential of ESBTs, it must be possible to develop a knowledge base in one ESBT and transfer the knowledge into another. Porting a knowledge base across ESBTs requires a clear understanding of the mechanical knowledge representation properties supported by each tool. In the following discussion, properties considered include: canonicity; truth value; plausibility, certainty, and possibility (PCP); temporality; and procedural knowledge. The nature of each property is described along with comments on related knowledge base characteristics. A summary table appears below relating these properties to several popular ESBTs. Overlap found in many of the mechanical knowledge representation properties suggests that automatic knowledge base translation is feasible.
