Methods The first step was to build a text mining and analysis environment based on Python language, and built a corpus based on the core chapters of SESD. The second step was to digitalize the corpus. The main steps included word segmentation, information cleaning and merging, document-entry matrix, dictionary compilation and information conversion. The third step was to mine and display the internal information of SESD corpus by means of word cloud, keyword extraction and visualization. Results NLP played a positive role in computer recognition and comprehension of SESD. Different chapters had different keywords and weights. Deficiency syndrome elements were an important component of SESD, such as "Qi deficiency""Yang deficiency" and "Yin deficiency". The important syndrome elements of substantiality included "Blood stasis""Qi stagnation", etc. Core syndrome elements were closely related. Conclusions Syndrome differentiation and treatment was the core of SESD. Using NLP to excavate syndromes differentiation could help reveal the internal relationship between syndromes differentiation and provide basis for artificial intelligence to learn syndromes differentiation.展开更多

That the characteristics of natural monopoly,in the case of water industry, are that the infrastructure investments are very large,most of which are used to build the transportation system? The webs for transporting their products to their customers,and the products are identity goods or services.By examining the characteristics of natural monopoly,this paper proposed away to break upand remodel the industry of“natural monopoly”.The main clue of remodeling is that the governments,who represent the public and who have the power to control over public resources,should build and maintain a public web platform for the goods’ transportation uses, and break up the barrier ofthe entry so as to produce a market-oriented competitive structure.The running modeland the condition of remodeling are put forward and the cost-revenue analysis of the operation is briefly under consideration.展开更多
