4th WORKSHOP ON HYBRID LOGICS
LICS 2002 Affiliated Workshop
>>> JULY 25, 2002 <<<
Copenhagen, Denmark
SECOND CALL FOR PAPERS
THEME:
Hybrid logic is a branch of modal logic in which it is possible to
directly refer to worlds/times/states or whatever the elements of the
(Kripke) model are meant to represent. Although they date back to the
late 1960s, and have been sporadically investigated ever since, it is
only in the 1990s that work on them really got into its stride.
It is easy to justify interest in hybrid logic on applied grounds,
with the usefulness of the additional expressive power. For example,
when reasoning about time one often wants to build up a series of
assertions about what happens at a particular instant, and standard
modal formalisms do not allow this. What is less obvious is that the
route hybrid logic takes to overcome this problem (the basic
mechanism being to add nominals --- atomic symbols true at a unique
point --- together with extra modalities to exploit them) often
actually improves the behavior of the underlying modal formalism. For
example, it becomes far simpler to formulate modal tableau and
resolution in hybrid logic, and completeness and interpolation
results can be proved of a generality that is simply not available in
modal logic. That is, hybridization --- adding nominals and related
apparatus --- seems a fairly reliable way of curing many known
weaknesses in modal logic. For more general background on hybrid
logic, and many of the key papers, see the Hybrid Logics homepage:
http://www.hylo.net
HyLo at LICS is likely to be relevant to a wide range of people,
including those interested in description logic, feature logic,
applied modal logics, temporal logic, and labelled deduction.
Moreover, if you have an interest in the work of the late Arthur
Prior, note that this workshop is devoted to exploring ideas he first
introduced 30 years ago --- it will be an ideal opportunity to see
how his ideas have been developed in the intervening period.
In this workshop we hope to bring together researchers from all the
different fields just mentioned (and hopefully some others) in an
attempt to explore what they all have (and do not have) in common. If
you're unsure whether your work is of relevance to the workshop,
please check out the Hybrid Logics homepage. And do not hesitate to
contact the workshop organisers for more information. We'd be
delighted to tell you more. Contact details are give below.
INVITED TALKS
We are very pleased to announce that Professors Moshe Vardi and
Melvin Fitting have accepted to be invited speakers at HyLo at LICS.
Program and titles of the talks will be released in following announcement,
but we are already looking forward to hear about their perspective on Hybrid
Logics.
SUBMISSIONS:
We invite the contribution of research papers to the workshop. Please
send electronically an extended abstract of up to 10 A4 size pages,
in PostScript format to: carlos at science.uva.nl BEFORE the 26st of
APRIL, 2002. Please note that all workshop contributors are required
by the LICS organizers to register for FLoC 2002.

Using Semantics for Information Retrieval and Filtering
State of the Art and Future Research
Las Palmas, Canary Islands - Spain
2nd of June 2002
Held in conjunction with the
Third International Conference on Language Resources and Evaluation
(LREC 2002)
The goal of this full day workshop is to bring together researchers in
the domain of information retrieval, and in particular, researchers
concerned by the utility of enhancing queries with semantic
information gleaned from languages resources and processes.
Workshop scope and aims
- ---------------------
Several experiments have been carried out in the last 15 years
investigating the use of various resources and techniques (e.g.,
thesauri, synonyms, word sense disambiguation, etc.) to help refine or
enhance queries. However, the conclusions drawn on the basis of these
experiments vary widely. Results of some studies have led to the
conclusion that semantic information serves no purpose and even
degrades results, while others have concluded that the use of semantic
information drawn from external resources significantly increases the
performance of retrieval software. At this point, several question
arise:
- Why do these conclusions vary so widely?
- Is the divergence a result of differences in methodology?
- Is the divergence a result of a difference in resources? What
are the most suitable resources? Do results using manually
constructed resources differ in significant ways from results
using automatically extracted information?
- What is the contribution of specialized resources?
- Are present frameworks for evaluation (e.g., TREC) appropriate
for evaluation of results?.
These questions are fundamental not only to research in document
retrieval, but also for information searching, question answering,
filtering, etc. Their importance is even more acute for multilingual
applications, where,for instance, the question of whether to
disambiguate before translating is fundamental.
The goal of this workshop is to bring together researchers in the
domain of document retrieval, and in particular, researchers on both
sides of the question of the utility of enhancing queries with
semantic information gleaned from languages resources and processes.
The workshop will provide a forum for presentation of the different
points of view, followed by a roundtable in which the participants
will assess the state of the art, consider the results of past and
on-going work and the possible reasons for the considerable
differences in their conclusions. Ultimately, they will attempt to
identify future directions for research.
In view of the relevance of Word Sense Disambiguation (WSD) to
information retrieval, a part of the workshop will be dedicated to a
panel on Senseval and WSD evaluation
(http://www.itri.bton.ac.uk/events/senseval/). The purpose of the
panel is to open the discussion on the objectives and principles of
Senseval-3, the next evaluation exercise for WSD systems.
The panel will summarize the methodology and results of Senseval-2 and
consider the current state of WSD. Panelists will speak about the
following topics: Is the Senseval-2 method of evaluation adequate? Are
we building the right kind of lexical resources for real sense
disambiguation systems? Should we (and is it possible to) start an
application-specific evaluation track?
