“Text Analytics to Support Sense-making in Social Media: A Language-Action Perspective”
Friday, October 28, 2016

Rice Hall Auditorium
Host: Hongning Wang (hw5x)
This presentation summarizes the results from a five-year text analytics project examining social media sense-making capabilities in various industries, including telecommunications, health, and security. Despite their various benefits, social media technologies present two important challenges for sense-making. First, online discourse is plagued by incoherent, intertwined conversations that are often difficult to comprehend. Moreover, existing text analytics tools mostly focus on the semantic dimension of language, as opposed to actions and intentions. I use real-world examples to illustrate how these challenges inhibit our ability to perform many basic social media analytics tasks such as identifying important participants, issues, and ideas. The Language-Action Perspective (LAP) emphasizes pragmatics; considering conversations, actions, and context. In order to address the two aforementioned challenges, we developed a LAP-based text analytics framework to support sense-making in online discourse. I present evaluation results from multiple social media channels and industries, including an extended field experiment utilizing a large cloud-based system developed based on the framework. The results have important implications for online sense-making, social media analytics, and how we think about text.
