[ntcir:162] INEX 2005 Workshop on Element Retrieval Methodology


INEX 2005 Workshop on Element Retrieval Methodology
Saturday, 30 July 2005 - University of Glasgow

The INitiative for the Evaluation of XML Retrieval (INEX), and the
University of Glasgow invite participation in the INEX Workshop on
Element Retrieval Methodology.  The workshop is to be held in Glasgow
as part of an information retrieval research festival.

The annual INEX workshop examining element retrieval has shown
improvements in retrieval precision, while at the same time raising
new questions about element retrieval methodology.  The annual
evaluation workshop focuses on retrieval performance; this mid-year
workshop will focus on methodology.

Opinion papers discussing XML element retrieval are sought.  Topics
include but are not limited to Theory, Application, Measurement,
Judgment, and Experience.  Note that relevance ranking algorithms are
excluded (they are the focus of the annual INEX workshop

What is the perfect collection and what is the ideal way to interact
with it?  Is a heterogeneous collection diverse in DTDs or diverse in
content? How should queries of this collection be specified in either
a formal or natural language?  When a user provides feedback are they
providing information about the element (e.g. too large) or the
content of the element?

Is there an existing application of element retrieval either
commercially or academically?  Can user modeling of this application
be used to identify unaddressed problems or formally define existing
problems?  How is element retrieval used, and what is it used for?
What is a relevant element in (a given) context, and how can
performance be measured within this context?

What are current element retrieval metrics actually measuring? What
would the ideal metric measure?  There already exists a plethora of
metrics so new metrics are not of interest, what is of interest is
the identification of what should be measured.

What can be determined from the existing INEX relevance judgments?
Can an E3S3 element validly be the child of an E3S3 element, and if
so then what does it mean? Is the 10 point relevance scale understood
by the judges?  How and when does a relevant element have no relevant
descendants and what are the implications of this?  How much
information is needed for an element to become relevant (can a
reference make an element relevant)?  Note that the existing INEX
online assessment software is not under discussion.

What can the experiments of TREC (trec.nist.gov), CLEF
(www.clef-campaign.org), and NTCIR (research.nii.ac.jp/ntcir) bring
to element retrieval and INEX?  How (if at all) is XML element
identification like spoken document retrieval, video document
retrieval, or passage retrieval?  Is element retrieval a form of
topic distillation, and how might experience in topic distillation be
used for element retrieval?

Any other topic related to XML element retrieval methodology is
welcomed. Discussion of relevance ranking algorithms is not - they
are the focus of the end of year INEX workshop.

Opinion papers discussing any of the above topics, or any other topic
related to XML retrieval methodology (excluding relevance ranking)
are sought.  Contributions formatted according to the ACM SIG
Proceedings guidelines (www.acm.org/sigs/pubs/proceed/template.html)
and not exceeding 8 (eight) pages should be submitted by email to
Mounia Lalmas (mounia@xxxxxxxxxxxxxx) and Andrew Trotman
(andrew@xxxxxxxxxxxxxx). Submissions should be formatted in PDF.

On-topic contributions will be combined into a publicly-available
proceedings.  This will form a discussion document for the workshop
(so please read it).  From this the program committee will choose the
most fiercely debated topics for discussion at the workshop.

The workshop will consist for 4 (four) sessions, each discussing one
topic. Sessions will commence with a 30 minute discussion-raising
presentation (by invitation) followed by a 90 (ninety) minute open
discussion.  Notes will be taken and made available.
