Abstract

People of all walks of life are using social media for various purposes and in unprecedented ways. With the sheer number of users who actively participate in numerous online activities, massive amounts of social media data are being continually generated, and it is undoubtedly big data. Conventional data differs from social media data that is often linked and noisy, which presents new challenges and makes less effective conventional data mining methods. We will introduce the intricacies of social media data, present some pressing challenges, and discuss how we can use it to gain meaningful insight and deep understanding for real-world applications, by exploiting its unique characteristics to develop novel algorithms and computational tools and by outlining some opportunities for further research and development.

Short Bio

Dr. Huan Liu is a professor of Computer Science and Engineering at Arizona State University. He obtained his Ph.D. in Computer Science at University of Southern California and B.Eng. in EECS at Shanghai JiaoTong University. He was recognized for excellence in teaching and research in Computer Science and Engineering at Arizona State University. His research interests are in data mining, machine learning, social computing, and artificial intelligence, investigating problems that arise in many real-world applications with high-dimensional data of disparate forms such as social media, group interaction and modeling, data preprocessing (feature selection), and text/web mining. His well-cited publications include books, book chapters, encyclopedia entries as well as conference and journal papers.
