'Comments in Tags, Please!': Tagging practices on Tumblr

The corpus analyzed in the study comprises two datasets collected from the general 'Trending' page of Tumblr and 60 fan communities ('fandoms'). Comment tags and their identified discourse functions (opinion, reaction, aside) are analyzed quantitatively for differences regarding use, structure, and sentiment. The analysis shows significant differences between the comment tags and traditional keyword tags, as well as among comment tags with the three different discourse functions. The results suggest that social tagging practices on Tumblr are influenced both by the technological specifications of the platform and the social structure of the website.
