Web data mining is a new subject which has been applied in many fields. With the rapid development of electronic commerce, the consumers have started to accept this kind of online shopping purchasing way. E-commerce websites have increasingly brought economic income. But on the other hand, this also brings several problems. Some of them are the instability of customers and high customer churn rate. So in this paper, we will analyze the electronic commerce customer churn prediction model based on Web data mining. Network and information security issues, have become a bottleneck for further development of the network economy. Web data mining technology is the key to improve the performance of network information security technology. And we will use the Pareto / NBD model to figure out the customers’ activity to predict the trend of the customers, which can be useful for the enterprise to formulate retaining strategies and resistance strategies to control website customers churn.

Abstract Combining the advanced arm architecture and embedded Linux operating system and equipment running information test and diagnosis technology, the power of the embedded Linux intelligent agricultural machinery equipment condition monitoring system was designed and developed. The whole monitoring system is divided into two parts, the foreground and the background. 3S technology as the core of the research and development of digital agriculture spatial information... Combining the advanced arm architecture and embedded Linux operating system and equipment running information test and diagnosis technology, the power of the embedded Linux intelligent agricultural machinery equipment condition monitoring system was designed and developed. The whole monitoring system is divided into two parts, the foreground and the background. 3S technology as the core of the research and development of digital agriculture spatial information management platform is a breakthrough in digital agriculture research. In recent years, supported by agricultural research information management system development has laid a good foundation. Front desk is mainly used for data collection and simple data analysis, these data for monitoring the status of the agricultural, including information, position information, state of the engine, torque converter oil temperature, brake system pressure, transmission oil temperature etc.. Background to provide a powerful data processing function, used to collect the data for further analysis and processing. And these data of an effective combination of cloud technology achieve the command and dispatch of agricultural machinery and effectively achieve the monitoring of equipment operating conditions, with obvious practical and engineering application value.

Abstract The ideological and political education are expected to shape the future society. In this paper, we proposed a multi-agent system which integrates the Intelligent Network Teaching System. We have tested the developed system in the real class room and found that the system improved the university thought political lesson teaching effect and learning efficiency....
