Time and Event Recognition for Question Answering Systems
An ARDA Workshop on Advanced Question Answering Technology
January
- July, 2002
James Pustejovsky, Organizer
The purpose of this workshop is to address the problem
of how to enhance natural language question answering systems to answer
temporally-based questions about the events and entities in news articles.
The two goals of this workshop are: (1) to examine how to formally distinguish
events and their temporal anchoring in text (news articles); and (2) to
evaluate and develop algorithms for identifying and extracting events and
temporal expressions from texts.
A specification language for events and temporal expressions
will be defined and developed as a deliverable of the workshop. Once the
initial definition and specification is complete, work will begin on annotation
on a large number of news articles, in order to create a Temporal Gold
Standard (TIMEBANK). Finally, the workshop will evaluate existing temporal
extraction algorithms, and adapt and extend their functionality and coverage
to meet the standard being defined.
