Abstract

On social media platforms and Twitter in particular, speci fic classes of users such as influencers have been given satisfactory operational de finitions in terms of network and content metrics. Others, for instance online activists, are not less important but their characterisation still requires experimenting. We make the hypothesis that such interesting users can be found within temporally and spatially localised contexts, i.e., small but topical fragments of the network containing interactions about social events or campaigns with a signifi cant footprint on Twitter. To explore this hypothesis, we have designed a continuous user profi le discovery pipeline that produces an ever-growing dataset of user profiles by harvesting and analysing contexts from the Twitter stream. The profi les dataset includes key network and content-based users metrics,enabling experimentation with user-de fined score functions that characterise specifi c classes of online users. The paper describes the design and implementation of the pipeline and its empirical evaluation on a case study consisting of healthcare-related campaigns in the UK, showing how it supports the operational de finitions of online activism, by comparing three experimental ranking functions. The code is publicly available.
