SocialXYZ Presentation @ Cal State University, Sonoma State

The design and evaluation of a sentiment analyzing discussion board was used to support learning and interaction within an existing online social networking (OSN) system. More specifically, this research introduces an innovative extension to learning management software (LMS) that combines real-time sentiment analysis with the goal of fostering student engagement and course community. In this research we perform data mining to extract sentiment on over 6,000 historical discussion board posts. This initial data was analyzed for sentiment and interaction patterns and used as the guiding design principle for redesigning an existing asynchronous online discussion board (AOD). The redesign incorporates a sentiment analyzer, which allows users to analyze the sentiment of their individual contributions before submitting. Through a controlled experiment the software was measured using content analysis, social network analysis and survey data.
