AI SEMINAR
Thu, May 19, 2016 @ 11:00 AM - 12:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Filippo Menczer, Professor, University of Indiana, Bloomington
Talk Title: The Spread of Misinformation in Social Media
Series: AI Seminar
Abstract: As social media become major channels for the diffusion of news and information, they are also increasingly attractive and targeted for abuse and manipulation. This talk overviews ongoing network analytics, data mining, and modeling efforts to understand the spread of misinformation online and offline. I present machine learning methods to detect astroturf and social bots, and outline initial steps toward computational fact-checking, as well as theoretical models to study how truthful and truthy facts compete for our collective attention. These efforts will be framed by a case study in which, ironically, our own research became the target of a coordinated disinformation campaign. Joint work with many members and collaborators of the Center for Complex Networks and Systems Research and the Indiana University Network Science Institute. This research is supported by the National Science Foundation, McDonnell Foundation, and DARPA. Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of these funding agencies.
Biography: Filippo Menczer is a professor of informatics and computer science, adjunct professor of physics, and a member of the cognitive science program at Indiana University, Bloomington. He holds a Laurea in Physics from the University of Rome and a Ph.D. in Computer Science and Cognitive Science from the University of California, San Diego. Dr. Menczer has been the recipient of Fulbright, Rotary Foundation, and NATO fellowships, and a Career Award from the National Science
Foundation. He currently serves as director of the Center for Complex Networks and Systems Research, as a member of the Scientific Leadership Team of the IU Network Science Institute, and is a Fellow of the Institute for Scientific Interchange Foundation in Torino, Italy, a Senior Research Fellow of The Kinsey Institute, and an ACM Distinguished Scientist. He previously served as division chair in the IUB School of Informatics and Computing, and was Fellow-at-large of the Santa Fe Institute. His research focuses on Web science, social networks, social media, social computation, Web mining, distributed and intelligent Web applications, and modeling of complex information networks. His work has been covered in many US and international news
sources, including The New York Times, Wall Street Journal, Washington Post, NPR, CNN, BBC, Nature, and Science.

AI SEMINAR
Fri, May 20, 2016 @ 11:00 AM - 12:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: James Gleeson, Professor, University of Limerick
Talk Title: Competition and avalanches in social spreading phenomena
Series: AI Seminar
Abstract: We consider the spreading of memes (distinct pieces of information like ideas, hashtags, URLs, etc.) on a large directed social network, like Twitter. We use a branching-process model to describe how users choose among multiple sources of incoming information, similar to models used in other studies, which rely on intensive computational simulations to fit to data. In contrast, we here develop analytical insights into the respective roles of the network degree distribution, the memory-time distribution of users, and the competition between memes for the limited resource of user attention. The result is a form of self-organised criticality, which we dub competition-induced criticality. Using this analysis, we fit the model to data on Twitter hashtags, and predict features of the time-dependent data. This work is in collaboration with Yamir Moreno, Raquel A. Baños (both Universidad de Zaragoza), and Kevin O Sullivan (University of Limerick)
Biography: Professor James Gleeson holds the Chair in Industrial and Applied Mathematics at the University of Limerick. He is a graduate of University College Dublin in Mathematical Sciences and Mathematical Physics and received his PhD in Applied Mathematics from Caltech in 1999. Following his graduation from Caltech, he was a visiting assistant professor in Arizona State University, and then moved to University College Cork for 7 years, before taking up his current position at the University of Limerick. He is an Associate Editor of the Journal of Complex Networks; is a council member of the European Consortium for Mathematics for Industry, and was appointed to the Irish Research Council by Minister Sean Sherlock in 2013. As co-director of MACSI, the Mathematics Applications Consortium for Science and Industry, he leads research into applications of mathematics to real-world problems with significant economic and social impact. His research interests include stochastic dynamics and contagion on complex networks

NL Seminar-Natural Language Communication with Computers
Fri, May 20, 2016 @ 03:00 PM - 04:00 PM
Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Yonatan Bisk, USC/ISI
Talk Title: Natural Language Communication with Computers
Series: Natural Language Seminar
Abstract: We propose a framework for devising testable algorithms for bridging the communication gap between humans and robots. We begin with a setting in which humans give instructions to robots using unrestricted language commands, with instruction sequences aimed at building complex goal configurations in a blocks world. I will present details of our data-collection effort, and preliminary results on action understanding. Time permitting, I will present new baseline results for flipping the semantic parsing paradigm to address the problem of language generation, where a human performs commands produced by a machine to demonstrate basic two-way communication.
Biography: Yonatan Bisk received his PhD from UIUC in 2015 under Professor Julia Hockenmaier and is now a Postdoc with Daniel Marcu at ISI.
