Speech Title: Measuring Twitter User Influence Through a Discrete Event
Abstract: NASA is viewed as a prime piece of the frontier of human knowledge by several generations, and is relied upon to educate the public on astronomical matters. With the Great American Eclipse of 2017, NASA’s production was crucial to the general public’s awareness and understanding of the event. With the explosion of data mining avenues and techniques, being able to study and quantify such major events has become of utmost importance for many of the involved. Our goal with this research is to understand how the public perceived the social media coverage that NASA had provided. We accomplish this through sentiment analysis and the spotting of trends within Twitter data. Furthermore, we follow a framework of study that allows simple and cost-effective analysis of discrete events of arbitrary nature in the future.
