Propa: a papaya management expert system

摘要

Professor Papaya (Propa) is an expert system that solves disease, nutrition, insect and other problems related to papaya management. A moderator manages the interaction between the user and a panel of experts. During a session, the moderator periodically chooses a lead expert to work with the user. The role of the moderator and the knowledge of each member of the panel of experts are implemented as software routines. Dynamic relevance factors aid in the identification of the lead expert. Blackboards serve as communication devices between the user and panel. Propa can diagnose problems, recommend solutions and display and print articles related to papaya crop management and postharvest handling problems.
