Description

Social media such as Twitter, Reddit, and Facebook, have become de facto global communication channels to disseminate news, entertainment, and one’s self-revelations. However, though these organizations provide real-time data feeds that may be utilized in many ways, how does one actually go about using these data? \ \ This tutorial will provide hands-on instruction regarding the collection, processing, and analysis of these data. First, we present an overview of our experiences using Natural Language Processing (NLP) techniques to operationalize social media data for use in locational analysis. Next, through a series of three exercises, we will demonstrate: \ \ 1) How the use of the open-source tool GATE may be customized for the NLP of a Tweet corpus; \ \ 2) How Topic Modeling tools such as Mallet can help facilitate an understanding of social behavior; and \ \ 3) How Geographic Information Systems (GIS) can enhance social media analysis via advanced locational analytics and reveal connections between these “conversations” and real-world events. \ \ In addition to the tutorial activities, a concluding group activity and discussion will be facilitated focusing on the research areas revealed during the tutorial along with the key takeaways concerning the ongoing use of the techniques and tools utilized during the tutorial and the next learning steps for participants. \ \ This tutorial is sponsored by the SIGGIS Mini-Track. \
