  We present EventPlus, a temporal event understanding pipeline that integrates
various state-of-the-art event understanding components including event trigger
and type detection, event argument detection, event duration and temporal
relation extraction. Event information, especially event temporal knowledge, is
a type of common sense knowledge that helps people understand how stories
evolve and provides predictive hints for future events. EventPlus as the first
comprehensive temporal event understanding pipeline provides a convenient tool
for users to quickly obtain annotations about events and their temporal
information for any user-provided document. Furthermore, we show EventPlus can
be easily adapted to other domains (e.g., biomedical domain). We make EventPlus
publicly available to facilitate event-related information extraction and
downstream applications.
