The Social Web Observatory is an entitydriven, sentiment-aware, event summarization web platform, combining various methods and tools to overview trends across social media and news sources in Greek.SWO crawls, clusters and summarizes information following an entitycentric view of text streams, allowing to monitor the public sentiment towards a specific person, organization or other entity.In this paper, we overview the platform, outline the analysis pipeline, focusing on the article clustering and title extraction aspects.We then perform a user study aimed to quantify the usefulness of the system and especially the meaningfulness and coherence of discovered events in a Greek language setting, getting promising results.
