A Comparative Analysis of Social Network Pages by Interests of Their Followers
Table 1: Percent agreement for expert analysis of community adherence
['Expert No.', 'Rock', 'Reenactment', 'Football', 'Vegetarianism', 'Control']
10 experts (linguists, sociologists, marketing specialists) gave their opinion on what community manifests itself in every sample. We instructed experts to define if authors in the sample dialogue are a community and, if yes, explain why they think so. Thus, the expert answers were formulated freely without the aim of interest attribution. Some of them preferred to just name the community (“vegans”, “rockers”); some stated the object of interest (“vegetarianism”, “rock music”). If these keywords were mentioned, we assigned 1 point to the answer (a True Positive answer); if no or some other keywords were mentioned (“music addicts” instead of “rockers”), we assigned 0 points. To see which samples relate to the most unanimous decision, we calculated percentage of True Positive answers in every column (percent agreement).
