Research On Construction Technology Of Knowledge Graph And Recommendation Of Operation Method For Plantation Cultivation

This paper investigates the research status and development trends of forestry expert decision-making systems in the world.To solve the problem in the expert decision system of cultivating forest plantation,a knowledge service and recommendation of operation method system for plantation cultivation was designed and built from the perspective of forest farmers.In order to solve the problem of strong artificial dependence and lack of confidence evaluation in the reasoning process of plantation cultivation and management,this paper studies the rule extraction technology,focusing on how to construct inference rules between site conditions and tree species,and adds the actually available confidence evaluation indexes in the rules.The existing reasoning algorithms are analyzed and summarized,the factor weight analysis method is used to process and calculate based on the practical application of confidence in the reasoning process.Finally,the user is provided with the cultivation decision-making and the reliability of the results obtained according to the input conditions.It improves the scientific of decision-making of plantation cultivation.In view of the difficulty of forest farmers to query the related knowledge of artificial forest cultivation and the gap of Knowledge Graph in the field of artificial forest cultivation,This paper studies the basic theory and technology of knowledge extraction and construction of plantation's Knowledge Graph,collects the knowledge needed by forest farmers in the process of assistant decision-making,puts forward the concept of Knowledge Graph of plantation cultivation,constructs knowledge graph of plantation cultivation,realizes the visualization of related knowledge of forest plantation.It provides knowledge services for the whole process of forest plantation cultivation.On the basis of the above,a B/S-based knowledge service and recommendation of operation method system for plantation cultivation is developed in this paper,which can realize the functions of matching tree species with site and cultivation plan recommendation,as well as the knowledge service needed in the whole process of plantation cultivation.This study is of great significance to the development of forest plantation cultivation and management,and can better serve for forest farmers.
