Real-time News Event Extraction for Global Monitoring Systems
نویسندگان
چکیده
This paper presents a real-time news event extraction system developed by the Joint Research Centre of the European Commission. It is capable of accurately and efficiently extracting violent and natural disaster events from online news without using much linguistic sophistication. In particular, in our linguistically relatively lightweight approach to event extraction clustered news have been heavily exploited at various stages of processing. The systems’ architecture, automatic pattern learning, our new pattern specification language, and information aggregation techniques are briefly described in this paper. Next, the issues of integrating event information in a global monitoring systems are addressed too. Finally, the results of accuracy evaluation are presented.

متن کاملOnline-Monitoring of Security-Related Events
This paper presents a fully operational real-time event extraction system which is capable of accurately and efficiently extracting violent and natural disaster events from vast amount of online news articles per day in different languages. Due to the requirement that the system must be multilingual and easily extendable, it is based on a shallow linguistic analysis. The event extraction result...
