Massive graph datasets are used operationally by providers of internet, social network and search services. Sampling can reduce storage requirements as well as query execution times, while prolonging the useful life of the data for baselining and retrospective analysis. Here, sampling must mediate between the characteristics of the data, the available resources, and the accuracy needs of queries. Inference methods can be used to fuse datasets which individually provide only an incomplete view of the system under study. In this talk we describe some successes in applying these ideas to massive Internet measurements and some potential new applications to inverse problems in urban informatics, and to bioinformatics.
