Twitter Data Analysis
Twitter Data AnalysisThis workflow examines a sample of tweets from the days surrounding the scottisch referendum for independence in 2014 [1]. After reading the data from a localdatabase, basic text processing is used to extract hashtags from the dataset and term frequencies calculated and used to build a tag cloud. Subsequently, hashtagtrending is examined over time, with a notable post election surge in the #the45 movement. Additionally, network analysis is performed in order to look at the mostinfluential social graph surrounding this issue.
