Popis: Nowadays, many influential facts are re- ported multiple times by different sources and in different languages. This paper presents the results of an experiment on deploying cross-lingual information fu- sion techniques for refining the results of a large-scale multilingual news event extrac- tion system. Circa 10% of event descrip- tions extracted by the mono-lingual sys- tems could be refined. The overall gain in recall and precision against the best mono- lingual system was 6,4% and 4,8% respec- tively.
