Predicting Elections with Twitter: What 140 Characters Reveal about Political Sentiment (Tumasjan et al.)
Successful use of social media in las presidential campaign has established twitter as an integral part of political campaign toolbox
Goal: analyze on Twitter: 1. Deliberation, 2. Sentiment, 3. Prediction
Previous work:
Deliberation: Honeycutt and Herring – Twitter not only used for one-way comm, but 31% of all tweets direct a specific addressee. Kroop and Jansen – political internet discussion boards dominated by small # of heavy users
Sentiment: How accurately can Twitter inform us about the electorate’s political sentiment?
Prediction: can Twitter serve as a predictor of the election result?
Data: examined more than 100k tweets and extracted their sentiment using LIWC
Target: German federal election 2009
Results:
1. While Twitter is used as a forum for political deliberation on substantive issues, this forum is dominated by heavy users
Two widely accepted indicators of blog-based deliberation:
-The exchange of substantive issues (31% of all messages contain “@”),
-Equality of participaion: While the distribution of users across groups is almost identical with the one found on internet message boards, we find even less equality of participation for the political debate on Twitter. Additional analyses have shown users to exhibit a party-bias in the volume and sentiment of messages.
2. The online sentiment in tweets reflects nuanced offline differences between the politicians in our sample.
LIWC profiles:
-Leading candidates: Very similar profile for all leading candidates, only polarizing political characters, such as liberal leader and socialist, deviate in line with their roles as opposition leaders. Messages mentioning Steinmeir (coalition leader) are most tentative
3. Similarity of profiles is a plausible reflection of the political proximity between the parties
Key findings: high convergence of leading candidates, more divergence among politicians of governin grand coalition than among those of a potential right wing coalition
4. Activity on Twitter prior to election seems to validly reflect the election outcome (MAE 1.65%), and joint party mentions accurately reflect the political ties between parties.
