Research On Ontology Of Rice Cultivation Knowledge Management System

Since the20th century, human development into the high speed era. At the same time,economic development and technology industry also rapid development. As the20thcentury’s most important computer industry, it have been integrated into the industries,produced many interdisciplinary subject. Although it is not a long time when entered a newcentury time, the computer industry also produce many changes, from the original databasemanagement stage to entering a new era of knowledge management. Knowledgemanagement for many areas has produced important influence.Worked as a philosophical field commonly used "Ontology" was gradually introduceinto knowledge management study, Seen from the semantic and knowledge level, it can begood for conceptual modeling of information system. At present, in artificial intelligence,library and information, and the semantic web, and many other areas have a goodapplication. In the agricultural domain, there have been many experts and scholars willintroduce the concept came in the rice. Based on rice as research object, and the ricecultivation knowledge related background, we constructed a rice cultivation ontology,realize management of rice cultivation knowledge. It takes knowledge management systemof rice cultivation as a semantic tool. For rice cultivation knowledge related field, semanticconcept explicitly defined, it realized the professional knowledge sharing and reuse, andrealized the dynamic management rice farming production process.This article mainly from the following several aspects of in-depth research:(1) Based on the OWL concept of rice cultivation ontology modeling. From theconcept of knowledge organization based on ontology of methods and general conceptualmodel, analyzed the concept of rice cultivation knowledge structure, classificationstandards of rice cultivation, and proposes the corresponding knowledge modelingframework, using the OWL achieve the rice cultivation as a knowledge representationeffectively.(2) Construction of Rice cultivation knowledge ontology for the research of theconcept of knowledge and the relationship between the semantic repeatability andredundancy of rice cultivation. Made the related properties and the existing justiceClearly, proposes the solution between the general problems of semantic solutions.(3) Based on ontology knowledge intelligent retrieval model of rice cultivation. Basedon ontology knowledge retrieval in the general methods and models such as starting point, combined with Agent, artificial intelligence technology proposed intelligent knowledgeretrieval model to realize the intellectualized inquires rice cultivation knowledge.The research results increase the rice cultivation of effective expression, knowledgereusing and sharing, as well as the rice cultivation management process of the intelligentmanagement ability. It provides decision-making to rice cultivation production. It hasimportant practical significance and value for research..
