Andrew G. West

Andrew G. West a Research Scientist at Verisign Labs of Verisign, Inc. in the greater Washington D.C. area. In Spring 2013 I completed my Ph.D. at the University of Pennsylvania in the Dept. of Computer and Information Science in Philadelpia, PA. I received my M.S.E. from Penn in 2010 and did my undergraduate study at Washington & Lee University in Lexington, VA where I received my B.Sc. in Computer Science in 2007.

At Verisign Labs I am applying techniques developed in my graduate work to Verisign's Internet-scale routing and security data. Our goal is to improve the availability, reliability, and safety of the Web via applied research, participation in technical forums, and the development of intellectual property assets. Verisign Labs is also recruiting new team members.

Prior to Verisign, my dissertation work investigated anti-abuse in collaborative information systems. Highlights included developing the STiki anti-vandalism tool that has removed 500,000+ unconstructive edits from Wikipedia. My article "Examining the Popularity of Wikipedia Articles..." was covered by Gizmodo and The Atlantic. My publication "Link Spamming Wikipedia for Profit" was awarded best paper at CEAS, and "What Wikipedia Deletes: Characterizing Dangerous Collaborative Content" was featured by the Chronicle of Higher Education.

More broadly, my research interests include Web 2.0 and network security, applied machine learning, electronic anti-abuse, underground economies, trust and reputation management, spatio-temporal metadata, Internet measurement, research ethics, and technical writing.

Software & Datasets

STiki (Spatio-Temporal analysis over Wikipedia): A Wikipedia anti-vandalism tool consisting of a back-end engine for real-time revision processing and a user-facing GUI which presents probable-vandalism to users. An extension to this software includes the code/analysis necessary to detect link spam edits. Software. [WEBSITE]

WikiAudit: Heuristics to detect unconstructive wiki changes from a provided set of IPs; useful for network admins and investigations into editor bias. Software. [WEBSITE]

Reputation Management Simulator: A framework to evaluate reputation algorithm performance. Software. Last updated: 2009/10/25. [ZIP | DIAGRAM-PNG]
