***** To join INSNA, visit http://www.insna.org ***** Hi Ian, I'm not sure if what I'm going to say answers your question, but I was wondering whether you could consider focusing on all the tweets of your dataset and measuring "happiness" on the text of each tweet, independently if it is a reply, a mention, an RT or anything. Of course, in this way, you don't have a proper network, unless you want to filter out just the RTs and the mentions, in which case you will do have a directed graph, or you would be pleased to consider some sort of a two-mode network (for instance, Twitter users and hashtags or any sort of Twitter "events," which may be automatically extracted from your Twitter data by searching for specific terms or keywords or doing Topic Modeling to detect their important categories). I'm doing some sort of similar analysis on a big dataset of tweets about the issue of Global Refugees during the last 8 months (since October 2015) and although it is an ongoing work I might send you the link to the Beaker Notebook where you could see our preliminary computations and visualizations. As a matter of fact, in what concerns hedonometrics, we're simply doing sentiment analysis (through NLTK's TextBlob) and we are measuring the scores of polarity and subjectivity.
