In the field of natural language question answering, users pose their
information needs as questions in a natural language like English, and
systems seek to respond with just the right information. The canonical
examples have brief answers, e.g. "The Beatles" to "What was John Lennon's
group?", "Dec. 8th 1980" to "When did he die?", but many questions seek
answers with multiple pieces: "What else do you know about him?" I will
present a system for finding these complex answers, and an evaluation tool
that helped us isolate our important improvements over similar systems.
