WORKSHOP ON OPEN-DOMAIN QUESTION ANSWERING
ACL'2001 Conference
Toulouse, France
July 7, 2001
Open-domain question answering (QA) represents a new challenge to both
commercial applications and academic research. When users have specific
questions, such as "What countries did Clinton visit in 1999?" or "How much
does a ThinkPad cost?", they would like to see one (or a few) succint
answer(s). This workshop will focus on technical issues that directly apply
to this challenge, in particular, theoretical and pragmatic issues involved
in the creation, evaluation and implementation of QA techniques. We
concentrate on QA that is automatic and either domain independent or
working within a large open domain, such as news or technical support.
To accommodate this need for automatically finding answers to open-domain
questions, several different fields of research come together - information
retrieval, natural-language processing and knowledge representation. This
workshop will provide a forum for discussions of QA as the combination and
integration of techniques from these three fields. We invite papers that
deal with QA topics or components in one or more of these fields, such as
answer identification using passage retrieval techniques, linguisitc
analysis of questions to determine their focus, parse-based matching of
questions and answers, text generation as used for formulating answers,
deriving answers from knowledge bases, defining confidence measures for
answers, etc. Other QA issues of interest are evaluation methods, user
interface issues and user studies, integration of QA within larger systems,
and commercial applications of QA.
Topics of interest include, but are not limited to:
- parsing of natural language used in analyzing questions
and answers
- semantic analysis and categorization of questions and
answers
- lexical resources and knowledge bases as used in QA
- knowledge acquisition and information extraction used in
QA
- empirical methods for QA
- methods for answer selection, synthesis and generation
- definitions of answer correctness and answer justification
- commercial applications for QA
- integration of QA in dialog systems and search systems
All papers should specifically focus on question answering.
