LREC 2010 Workshop on

Web Logs and Question Answering (WLQA2010)

Malta, Saturday 22nd May 2010


Submission deadline: 12th March 2010 (EXTENDED)

Motivation & Scope

An Information Retrieval system takes a user query and returns a ranked
list of documents. On the other hand, a Question Answering system
provides an exact answer [1]. There has been quite a long period of
research in factoid QA driven by annual tracks at CLEF [2], TREC [3] and
NTCIR [4]. The result of this work has been that it is possible to
construct systems which can answer simple factoid queries with high
accuracy. This has led to the belief that QA is a "solved problem" where
no more research is required. However, the questions are not usually
from real users, they are devised by the assessors at CLEF, TREC etc.
Secondly, they are restricted to certain well-known simple types which
are only a small subset of the real questions which people wish to ask.
Thirdly, questions are considered in isolation (or in some tracks a
fixed group) and not in a dialogue context whereas in our interactions
with people all questions are answered in context and with the
possibility for clarification. Thus, there is a need to inject new ideas
into QA research.

Recently there has been much interest in Web query logs and in
particular methods for analysing these in order to extract information
which can be used to improve IR systems [5,6]. Logs are typically
extremely large and contain naturally occurring and noisy data.
Automatic techniques (using for example statistical approaches or
machine learning algorithms) are therefore necessary since manual
approaches are not generally feasible.

The purpose of the workshop, therefore, is to investigate how some of
the methods developed for analysing web logs within an implicit IR
context can be applied to QA. For example:

* Can the meaning of IR queries in logs be deduced automatically in
order to extract the corresponding questions from them?

* Can NLP techniques developed within QA, e.g. Named Entity recognition
be applied to the analysis of query logs?

* Can logs be used to deduce useful new forms of question (i.e. not
simple factoids) which could be looked at next by QA researchers?

* Can questions grouped into sessions be comprehended in such a way as
to deduce the underlying implicit natural language dialogue consisting
of a coherent sequence of questions where each follows logically from
both the previous ones and the system's responses to them?

* Are there logs from real (or experimental) QA systems like lexxe.com
which can be obtained and what can be learned from them from the
perspective of designing evaluation tasks? What about logs from sites
like answers.com (where queries are answered by human respondents)?

* Are QA query logs different from IR query logs? Do users behave
differently in QA systems? Can QA-style questions be identified within
an IR log?

* Can click-through data - where the aim of a question can be inferred
from the returned documents which are inspected - be used for the
development of QA systems for example for the deduction of important
query types and their links to IR queries?

* Are there logs of transcribed speech made from telephone QA systems
which can be obtained and what analysis could be carried out on those,
using for example techniques developed at related tracks at CLEF such as
Cross-Language Speech Retrieval (CL-SR) and Question Answering on Script
Transcription (QAST)?

Historically, QA was a combination of NLP and IR. Much web log analysis
is a form of IR in which the same problem of retrieval is being
approached from a different direction, namely the queries themselves.
Thus we are proposing here a new combination, namely QA and log
analysis. These fields are complementary and share the goal of building
better systems for users.

Authors are invited to submit original research papers addressing
questions on the lines listed above. Papers must be related to QA and
must involve the use of a query log (but not necessarily of a QA
system). Submissions will be reviewed by members of the programme
committee and judged on technical quality, clarity and relevance to the

Papers should be no longer than 8 pages, set in accordance with LREC
guidelines and using the LaTeX or Word templates which are available
here: http://www.lrec-conf.org/lrec2010/?Author-s-Kit-and-Templates .

Papers should be submitted in pdf via the WLQA2010 START system:
https://www.softconf.com/lrec2010/WLQA2010/ . When using START, authors
will be asked to provide essential information about resources (in a
broad sense, i.e. also technologies, standards, evaluation kits, etc.)
that have been used for the work described in the paper or are a new
result of your research.  For further information on this new iniative,
please refer to
http://www.lrec-conf.org/lrec2010/?LREC2010-Map-of-Language-Resources .

Proceedings will be produced at the workshop and it is intended that
selected papers will be published in a journal special issue after LREC
has taken place.
