AIC Seminar Series
Detection of Imperative and Declarative Question-Answer Pairs in Email Conversations

Location: EJ228 (SRI E building) (Directions)
Question-answer pairs extracted from email threads
can help construct summaries of the thread, as well
as inform semantic-based assistance with email.
Previous work dedicated to email threads extracts
only questions in interrogative form. We extend the
scope of question and answer detection and pairing
to encompass also questions in imperative and
declarative forms, and to operate at sentence-level
fidelity. Building on prior work, our methods are
based on learned models over a set of features that
include the content, context, and structure of email
threads. For two large email corpora, we show
that our methods balance precision and recall in extracting
question-answer pairs, while maintaining a
modest computation time.
