Informationization has entered the era of big data; the existing information platform is difficult to assume the task of information gathering and analysis. For this reason, we build an information system for social institutions and civil sector based on virtual cloud platform.

Quantitative research has been extensively applied in sociology. The traditional way of using data statistical computing tools of R, SPSS and Stata on the stand-alone machine can't deal with the challenges of big data; furthermore, the demand of complex computing in mobile condition is increasing due to the fieldwork characteristics of sociological researchers. Considering the computing needs of sociological...
Signal processing on graph is attracting more and more attention. For a graph signal in the low-frequency subspace, the missing data on the vertices of graph can be reconstructed through the sampled data by exploiting the smoothness of graph signal. In this paper, two iterative methods are proposed to reconstruct bandlimited graph signal from sampled data. In each iteration, one of the proposed methods...
