The paper adopts the fuzzy c-means text mining method in lots of text mining methods. But aim at the defect that the initial value of the fuzzy c-means is more sensitivity and poor stability, an improved GAFCM text mining method has been put forward. GAFCM uses global search features of genetic algorithms to improve the fuzzy c-means. Finally, it has proved that the improved text mining method has...
According to the uncertainty of indexes in the bid evaluation of power equipment, the entropy value theory is applied to combine the traditional fuzzy comprehensive evaluation method for bid evaluation of power equipment. The coefficients of weight for evaluation factors are obtained from the avail value of data reflecting the information entropy. This method is applied for bid evaluation of power...
In the system of highly globalized world economy, corporate social responsibility has become main trends and methods, which made the corporate sustainable operation. Modern financial analysis, however, always based on the analysis of economic responsibility, ignored the legal responsibility, ecological responsibility and ethical responsibility. Such neglect has made not only the outcome of decision-making...
When the development of an oil field comes into the middle and later stage, it is difficult to grasp the dynamic law due to continuous rising of water cut. A key to realize the optimal control of the whole process of oil development is to realize the accurate forecast of development indexes. This paper mainly investigates the application of data mining methods in development indexes forecast of an...
