Massively Multi-Lingual Event Understanding: Extraction, Visualization,
  and Search
Chris Jenkins Shantanu Agarwal Joel Barry Steven Fincke Elizabeth Boschee
In this paper, we present ISI-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, ISI-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 English-speaking 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).
