Establishment and Challenges of Crop Expert System

本文闡述了作物專家系統的功能、發展概況、類型、趨勢、特性及建構技術體系，並指出目前作物專家系統研發上所面臨的問題和挑戰。知識庫的建構是研發作物專家系統的關鍵環節，其知識獲取必須匯集各相關領域專家之長，且應建立在以作物生育時間和生產管理技術為依據的作物知識模型之基礎上。從科技研發人員、基層技術推廣人員和農民不同層次之需求來建立作物專家系統是十分必要的。臺灣稻作資訊系統的研發過程及長期累積經驗，當可具體提供其他作物專家系統在知識庫建構上的參考。 This paper described the functions, developing course, classification, future trends, characteristics, and the construction technologies of crop expert system. The problems and challenges of developing crop expert system were also discussed. There is a need to combine and integrate the knowledge from different specialties for the development of crop expert system. Knowledge database is the key of establishing crop expert system, and the knowledge should be modeled. The foundation for building knowledge model of crop expert system is the crop growth-development time and production management technique. The crop expert system should be able to fulfill the requirements of different types of users: researchers, extensionists, and farmers. The developing process and long-term experience in Taiwan Rice Information System could be provided as a reference for the development of knowledge database in other crop expert systems
