Most people assume that a Google search can identify most of the information available on a given subject. But beyond the capabilities of Google or any other search engine, there is another online world. In fact, the number of non-indexed internet sites is estimated to be 500 times larger than what a search engine can reveal. And where the sun doesn’t shine, there exists a dark side of the Internet that is a conduit for all types of illegal and often dangerous activity. Wilson Center Public Policy Fellow Daniel Sui is attempting to uncover the web’s dark underbelly and begin the process of charting the uncharted. That’s the focus of this edition of Wilson Center NOW.

Daniel Sui is a Public Policy Fellow with the Wilson Center’s Science and Technology Innovation Program. He is also a Distinguished Professor of Social and Behavioral Science and Chair of the Department of Geography at The Ohio State University. His research focuses include volunteered geographic information and the use of social media as a new data source for geographic research as well as the legal and ethical issues of using geospatial technologies in society.
