Title: Volunteer-Based Online Experiments With Diverse Samples: Lessons Learned from Six Years of LabintheWild
Speaker: Katharina Reinecke, Assistant Professor of Computer Science & Engineering, University of Washington
Date: May 1, 2018
Time: 12:00-1:00pm
Room: Gates-Hillman Complex 6501
Abstract:
An estimated 95% of our scientific knowledge about people, their behavior, perception, and preferences is based on studies with “WEIRD” samples, an acronym for participants who are Western, Educated, Industrialized, Rich, and Democratic. My work in Human-Computer Interaction has shown that tech ..read more

Title: Socio-technical Challenges in Scientific and Medical Crowdsourcing
Speaker: Edith Law, Assistant Professor in Computer Science, University of Waterloo
Date: April 17, 2018
Time: 12:00-1:00pm
Room: Gates-Hillman Complex 6501
Abstract:
Science is increasingly data-intensive; yet, many research tasks involving the collection, annotation and analysis of data are too complex to be fully automated. The idea of research-oriented crowdsourcing is to engage people without formal academic training to contribute or process data towards answering questions. In this talk, I will discuss the variety ..read more

Title: Targeted Crowdsourcing with a Billion (Potential) Users
Speaker: Panos Ipeirotis, Professor in Department of Information, Operations,
and Management Sciences at NYU Stern School of Business
Date: April 10, 2018
Time: 12:00-1:00pm
Room: Gates-Hillman Complex 6501
Abstract:
We describe Quizz, a gamified crowdsourcing system that simultaneously
assesses the knowledge of users and acquires new knowledge from them.
Quizz operates by asking users to complete short quizzes on specific
topics; as a user answers the quiz questions, Quizz estimates the
user’s competence. To acquire new knowledg ..read more

Title: Muddied Waters: Online Disinformation during Crisis Events
Speaker: Kate Starbird, Assistant Professor in Human-Centered Design and Engineering, University of Washington
Date: March 20, 2018
Time: 12:00-1:00pm
Room: Newell-Simon Hall 1305
Abstract:
Since 2013, my collaborators and I have conducted research on how rumors and misinformation spread through social media during crisis events. Recently, our work has revealed how a subsection of the alternative media ecosystem facilitates the spread of disinformation—in the form of conspiracy theories or “alter ..read more

Title: Extreme Democracy
Speaker: Ariel Procaccia, Associate Professor in Computer Science, Carnegie Mellon University
Date: December 12, 2017
Time: 12:00-1:00pm
Room: Gates-Hillman Center 6501
Abstract:
I will present several forms of democratic decision making that go far beyond your run-of-the-mill election. Specifically, I will discuss (i) liquid democracy, which allows voters to transitively delegate their votes; (ii) participatory budgeting, in which residents of a city or country vote on how its budget should be divided; and (iii) virtual democracy, which automates ethical decis ..read more

Title: Towards a Universal Knowledge Accelerator
Speaker: Aniket Kittur, Associate Professor in Human-Computer Interaction Institute, Carnegie Mellon University
Date: October 17, 2017
Time: 12:00-1:00
Room: Gates-Hillman Center 6501
Abstract:
The human mind remains an unparalleled engine of innovation, with its unique ability to make sense of complex information and find deep analogical connections driving progress in science and technology over the past millennia. The recent explosion of online information available in virtually every domain should present an opportu ..read more

Title: Learning from People
Speaker: Nihar B. Shah, Assistant Professor in Machine Learning and Computer Science, Carnegie Mellon University
Date: October 10, 2017
Time: 12:00-1:00pm
Room: Gates-Hillman Complex 6501
Abstract:
Learning from people represents a new and expanding frontier for data science. Two critical challenges in this domain are of developing algorithms for robust learning and designing incentive mechanisms for eliciting high-quality data. In this talk, I describe progress on these challenges in the context of two canonical settings, namely those of ranking and cla ..read more

Title: Solving Photo Mysteries with Expert-Led Crowdsourcing
Speaker: Kurt Luther, Department of Computer Science, Virginia Tech
Time: 12:30 - 1:30pm
Room: Gates-Hillman Complex 6501
Abstract:
Despite the old adage that a picture is worth a thousand words, images often need context to be meaningful to their viewers. In this talk, I show how expert-led crowdsourcing, a novel approach that combines the relative strengths of experts and amateur crowds, can be used to solve photo mysteries. In one example, I conducted a qualitative study of image verification experts in journalism, national ..read more

Title: Supporting Collective Ideation at Scale
Speaker: Pao Siangliulue, Department of Computer Science, Harvard University
Date: April 18, 2017
Time: 12:30 - 1:30pm
Abstract:
A growing number of online collective ideation platforms, such as OpenIDEO or Quirky, have demonstrated the potential of large-scale collaborative innovation in various domains. However, these platforms also introduce new challenges. People have to wade through a sea of possibly mundane and redundant ideas before encountering genuinely inspiring ones. Further, once all ideas are collected, the communities have to spend ..read more

Title: The Collaboration and Communication Networks within the Crowd
Speaker: Siddharth Suri, Microsoft Research, New York City
Time: 12:30-1:30pm
Room: Newell-Simon Hall 1507
Title: The Collaboration and Communication Networks within the Crowd
Abstract:
Since its inception, crowdsourcing has been considered a black-box approach to solicit labor from a crowd of workers. Furthermore, the crowd has been viewed as a group of independent workers dispersed all over the world. One goal of this work is to show that crowdworkers collaborate to fulfill technical and soci ..read more
