Abstract

Safapp is a tool that crawls and analyses data from social media (specially Twitter and blogs) in the context of radicalization detection. This app has been developed in the context of SAFFRON European project. This paper focuses on the description of the semantic module of Safapp which is dedicated to the analysis of textual content of social networks and blogs, and more specifically on a newly developed module: the event extractor. With this module we expect to go one step further in the development of useful tools to track and analyze online propaganda.
