Frontex real-time news event extraction framework

An ever-growing amount of information relevant for early detection of certain threats can be extracted from on-line news. This led to an emergence of news mining tools to help analysts to digest the overflow of information and to extract valuable knowledge from on-line news sources. This paper gives an overview of the fully operational Real-time News Event Extraction Framework developed for Fron-tex, the EU Border Agency, to facilitate the process of ex-tracting structured information on border security-related events from on-line news. In particular, a hybrid event extraction system has been constructed, which is applied to the stream of news articles continuously gathered and pre-processed by the Europe Media Monitor—a large-scale multilingual news aggregation engine. The framework con-sists also of an earth browser, in which events are visual-ized and an event moderation tool, which allows to access the database of automatically extracted event descriptions and to clean, validate, group, enhance and export them into other knowledge repositories
