Title:

Mining the Deep Web and Online Social Networks by Sampling

Abstract:

A growing proportion of daily human activities are recorded and served by various hidden web sites. In addition to online social networking and media sites (OSNs), there are millions of other hidden web data sources. In this digitalized world, a question of interests to both data providers and their users is: whatinformation can be inferred statistically from a sample obtained remotely from restrictive web interfaces. The information inferred ranges from individual traits, to summarizing statistics and network structural properties. The answer to this question has applications in business intelligence, social media marketing, criminal group detection, and political mobilization. While our main goal is to uncover the hidden properties, the same techniques can be also used by data providers to design the searchable interface to protect the data.

In this talk I will present several estimation techniques in the context of graph, and give an application in the detection of millions of fake followers in Weibo.
