Twitter Analytics: Dutch Political Parties

Politicians are adopting social media, creating an avenue for social science research. However, social media data is largely unstructured. This work analyzes tweets sent by 144 members of Dutch parliament over a period of three months. We cluster hashtags based on co-occurrence to identify discussed topics. This approach produces clusters of reasonable quality, but the identified topics are perhaps too specific to be used in political science research.
