摘要：

Social media, e.g., Facebook and Twitter, have drastically changed personal information generation, distribution, and exchange. Massive streams of social media data provide alternatives to traditional data collection approaches like questionnaires or interviews for understanding personal opinions and observations and, thus, are increasingly investigated by researchers in many domains. Many social media has the location and time stamps associated with the posted information, and thus is regarded as a major spatiotemporal data source. Twitter, for example, introduced location-based services in 2010, which has opened new windows for studying spatiotemporal trends in social media data. In this talk, I present a smoothing spline ANOVA approach to analyze Twitter data. This talk is based on a joint work with Nate Helwig, Yizhao Gao, and Shaowen Wang.
