DiscussionDespite the deluge of data on human communication, dynamics of collective mood is still mainly an uncharted area. While different theories of emotion contagion exist in the literature, we are still far off being able to predict the occurrences, intensity and durations of collective compassion, happiness or outrage on Twitter. Here we presented findings from one large Twitter dataset. While we are conscious of some serious limitations of our approach–the lack of representativeness of Twitter users, and the noisy nature of sentiment scores–we believe that our methodology can be generalized to other datasets of human interactions which allow for sentiment RRx-001 web scoring.change in community sentiment compared to unmodified model community0.rsos.royalsocietypublishing.org R.

Additionally, it has become an exclusive channel to get the attention of some socio-demographic groups, especially in the younger population, who decreasingly consume traditional media such as local newspapers and television. For these reasons, a data-driven model of collective sentiment captured through social media is one of the most important tools that social data analytics can offer to a city leadership. It allows gaugingpublic opinion on different topics and understanding/predicting the dynamics of public opinion. Most HM61713, BI 1482694 web importantly, it can help to uncover public evaluation of local decisions. It also allows, as mentioned previously, to engage different communities into a conversation and to reach to under-represented groups. Our framework can be applied over a wide range of topics: energy, transport, education, tourism, local leadership and so on. We demonstrated that by using a number of community detection algorithms in combination with sentiment scores, we can identify stable communities of Twitter users. Users within these communities are well connected and send messages to each other frequently compared with how frequently they send messages to users not in the community.
