Understanding and Representing Human Services Knowledge

Expert systems-computerized decision consultants-offer potential for human service professionals to share expertise and reduce variability in decision making. The development of such systems is particularly important in the field of child protection because of high staff turnover and complex decision making requirements. This paper presents a method for knowledge acquisition in building a prototype expert system in child welfare. Patterns of decision making are traced and translated into computer-based rules. Solutions to research problems in developing expert systems are presented. Continued refinement of research practice in this area can lead to the development of usable expert systems for the social services.
