Associate Professor Jingrui He and Arun Reddy Nelakurthi, senior engineer in machine learning research at Samsung Research America, have coauthored a new guide to user behavior modeling. Their book, Social Media Analytics for User Behavior Modeling: A Task Heterogeneity Perspective, was recently published by CRC Press.

"Recent years have seen a rapid growth in social media use, both in terms of the number of users on each platform (e.g., Twitter) and the variety of platforms being used," said He. "This book aims to analyze the rich data from social media usage, in order to address research questions of data reliability and acceptance, data heterogeneity, and model transparency and trustworthiness."

The book includes a range of models and algorithms dedicated to each of the research questions and demonstrates their successful applications across several domains, such as healthcare.

"In collaboration with Mayo Clinic Arizona, we have deployed some of our algorithms to analyze diabetes patients' online social behaviors, as well as the connections with the patients' physical markers. This book is expected to inspire future work in this exciting research area," said He.

He's research focuses on heterogeneous machine learning, rare category analysis, active learning and semi-supervised learning, with applications in social network analysis, healthcare, and manufacturing processes. Prior to joining the iSchool, He worked as a faculty member at Arizona State University and Stevens Institute of Technology and as a research staff member at IBM. Her honors include an NSF CAREER Award, IJCAI Early Career Spotlight, and two IBM faculty awards. She is the author of Analysis of Rare Categories (Springer, 2012). She earned her PhD and MS in machine learning from Carnegie Mellon University and MEng and BEng in automation from Tsinghua University.

Sanfilippo examines privacy practices of disaster apps

With Hurricane Sally threatening the Gulf Coast last week, people in its path may have felt reassured by the mobile apps that would provide them with weather alerts or notify first responders in case of an emergency. While the app users may have been willing to share their location with first responders, they might be surprised to learn that their location and other personal information could be shared with a third party or accessed after the hurricane had passed. Assistant Professor Madelyn Sanfilippo and fellow researchers examine the privacy practices of popular disaster apps in the paper, "Disaster Privacy/Privacy Disaster," which was the lead article in a special issue of the Journal of the Association for Information Science and Technology (vol. 71, issue 9)  on information privacy in the digital age.
