Data processing of wide-area measurement system based on Hadoop Chichiang Julie; Zhang Shilin in order to solve the problem of data redundancy and low processing efficiency in the mass data processing of wide area Measurement system (WAMS), a WAMS data processing cloud computing platform based on Hadoop was designed and implemented. First, the architecture of the platform is given. Secondly, a wams mass data loading method based on Hadoop Distributed File System (HDFS) is designed and the MapReduce model is used to realize multiple file data.

The improvement of PageRank algorithm based on cloud computing Zhengjing A new method is proposed to solve the problem that the PageRank algorithm needs a lot of iterations in the web structure mining. This method improves the calculation formula of the original PageRank value and reduces the number of iterations. Experiments show that the new method reduces the consumption of network communication and access HDFs in the cloud computing environment, and is superior to the traditional PageRank algorithm in time cost. Improvement of PageRank algorithm based on cloud computing
