Massively Multi-Lingual Event Understanding: Extraction, Visualization, and Search

In this paper, we present IS I -CLEAR, a state-of-the-art, cross-lingual, zero-shot event extraction system and accompanying user interface for event visualization & search. Using only English training data, IS I -CLEAR makes global events available on-demand, processing user-supplied text in 100 languages ranging from Afrikaans to Yiddish. We provide multiple event-centric views of extracted events, including both a graphical representation and a document-level summary We also integrate existing cross-lingual search algorithms with event extraction capabilities to provide cross-lingual event -centric search, allowing Englishs-peaking users to search over events automatically extracted from a corpus of non-English documents, using either English natural language queries (e.g. cholera outbreaks in Iran) or structured queries (e.g. find all events of type Disease-Outbreak with agent cholera and location Iran).
