Design of Knowledge Base and Inference Engine in Intelligent Universal Land Evaluation System

摘要

Using the theory and method of expert system, this paper explores the knowledge type, knowledge expression, knowledge acquirement, basic controlling strategy and realization algorithm of inference engine in intelligent universal land evaluation system, all of which are based on analyzing the specialty flow of land grading and evaluation. It also creates a land evaluation system based on expert's knowledge, which could solve traditional problems of evaluation system in less of universality, flexibility and intelligent ability.
