Study On Agricultural Knowledge Fermenting And Knowledge Representation Based On The Theories Of Extenics

Our country is a traditional big agricultural country,famers have a great proportion in the population.To such a developing country,if it wants to get rid of the behindhand complexion and to become one of the developed countries,it would quicken steps of modern agriculture, then develop a way with Chinese characteristics in agricultural development.The meaning of knowledge agriculture is utilizing,absorbing primary knowledge to creat new knowledge and make knowledge as one of the most important factors.So processing knowledge innovation is the urgent affairs of accelerating our agricultural development.Based on the relevant economic theory and quantitative analysis method,supported by knowledge fermenting model,extenics, I study on the qualitative and quantitative analysis of two facets for agricultural organization how to process knowledge innovation, with a view to further reveal the mechanism of building a perfect system of knowledge innovation, accelerating the steps of modern agriculture accordingly.The thesis is divided into five chapters as follow:Chapter one, introduction, discusses the background and meaning of the research. It hereby introduces the main content, technological route and methods.Chapter two, knowledge agriculture and analysis on problems of the development of our country's knowledge agriculture, this chapter is based on analyzing the processing of knowledge agriculture that expatiate the meaning of it.Through the studying on the actuality of developed agricultural countries, I summarize the primary characters of knowledge agriculture.At last,I analyse the problems of the development of our county's knowledge agriculture.Chapter three, study on the agricultural knowledge fermenting model ,I use MR.HE's knowledge fermenting model to corporations for reference for studying on the problems of knowledge innovation and combined with the complexion of our country,build the knowledge fermenting models for agricultural enterprises and agricultural research institutes.I use the theories of extenics for the models and bring a concept of"extension feedback"forward newly so as to analyse the errors between the goals and results.I demonstrate it with examples at last and raise countermeasure and advice for agricultural knowledge innovation organizations of our country.Chapter four,knowledge representation based on the theories of extenics, this chapter summarizes the components,use of agricultural expert system tersely and the relative merits of some knowledge representation methods used frequently in the aspect of knowledge base representation,proposes a method based on the theories of extenics and production rule combined with examples,and uses it for agricultural knowledge representation,analyses the advantages on knowledge obtaining,knowledge inference and the perfection for knowledge base of agricultural expert system.Chapter five, conclusions and expectations of the article, draws the main points with creation of the article, and point out the main direction and the field which should be studied in the future.
