> Title:  Crowdsourcing using Mechanical Turk: Quality Management and

> On Wednesday, November 9, Prof. Panos G. Ipeirotis will visit our
> college to give a talk about his research. Panos is an Associate
> Professor and George A. Kellner Faculty Fellow at the Department of
> Information, Operations, and Management Sciences at Leonard N. Stern
> School of Business of New York University. His recent research
> interests focus on crowdsourcing and on mining user-generated
> content on the Internet. He received his Ph.D. degree in Computer
> Science from Columbia University in 2004, with distinction. He has
> received three "Best Paper" awards (IEEE ICDE 2005, ACM SIGMOD 2006,
> WWW 2011), two "Best Paper Runner Up" awards (JCDL 2002, ACM KDD
> 2008), and is also a recipient of a CAREER award from the National
> Science Foundation.

> Abstract:
> I will discuss the acquisition of "labels" for data items when the
> labeling is imperfect. Labels are values provided by humans for
> specified variables on data items, such as "PG-13" for "Adult
> Content Rating on this Web Page." With the increasing popularity of
> micro-outsourcing systems, such as Amazon's Mechanical Turk, it
> often is possible to obtain less-than-expert labeling at low cost. I
> will present strategies of managing quality in a crowdsourcing
> environment, showing in parallel how to integrate data acquisition
> with the process of learning machine learning models. I illustrate
> the results using real-life applications from on-line advertising:
> leveraging Mechanical Turk to help classify web pages as being
> objectionable to advertisers. Time permitting, I will also discuss
> our latest results showing that mice and Mechanical Turk workers are
> not that different after all.
