First, the back- ground and motivation behind the presented work is given. Next, the paper describes the event extraction processing chain, the specifics of the domain, i.e., illegal migration and related cross-border crime, and event moderation and visu- alisation aspects of the system.

In particular, the rapid growth of infor- mation published on the Internet in the last decade led to an emergence of advanced software tools which allow analysts to cope with this overflow of information. Most open-source information on the Web is in the form of free text. There- fore a vast bulk of research was focused on advancing the technologies for automatic content extraction from natural- language text. This paper gives an overview of an effort to construct tools for Frontex—the European Agency for the Manage- ment of Operational Cooperation at the External Borders of the Member States of the European Union—to facilitate automating the process of extracting structured and valu- able knowledge from on-line news articles. The target topicable knowledge from on-line news articles....
