Message 1: Workshop on Hybrid Logics (HyLo 2000)

Date: Mon, 8 May 2000 20:27:41 +0200
From: Carlos Areces <>
Subject: Workshop on Hybrid Logics (HyLo 2000)

 Twelfth European Summer School 
 in Logic, Language and Information
	 August 6-18, 2000 
		 Birmingham, Great Britain

 August 14-18, 2000 
 (Bringing Them All Together)



 - Deadline for submission: June 1st, 2000.


Modal logic suffers from a certain asymmetry: even though the basic
semantic notion in modal languages is truth at a state, classical
modal logics lack the expressive power to talk about the states
themselves. Whether we think of states as intervals, geometric points,
nodes in a feature structure, or individuals in a description, this is
a genuine weakness.

Hybrid Logics are modal languages which use "terms as formulas".
Although they date back to the late 1960s, the last three years have
seen a resurgence of interest, with new results in expressivity,
interpolation, complexity, and proof techniques. It has also become
clear that hybrid logics offer a theoretical framework for uniting the
work of a surprisingly diverse range of research traditions.

This workshop is likely to be relevant to a wide range of people,
including those interested in description logic, feature logic, modal
logics for information systems, temporal logic, and labelled deduction
for modal logic. 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 and students
from all the different fields just mentioned (and hopefully some
others) in an attempt to explore just what they all have (and do not
have) in common. If you're unsure whether your work is of relevant to
the workshop, please check out the newly opened Hybrid Logic Site:

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.


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: BEFORE 1st of JUNE, 2000.

Please note that all workshop contributors are required by the ESSLLI
organizers to register for the Summer School. The deadline for early
registration at ESSLLI is May 31st, 2000.


Papers accepted for the workshop will be made available from the
Hybrid Logic Site. Following the workshop, participants will be
invited to submit their contributions for publication in a special
issue of the Journal of Logic and Computation.

 * Submissions: June 1, 2000
 * Notification: June 30, 2000
 * Provisional workshop programme: July 15, 2000
 * Website-ready copy of all workshop contributions: July 31, 2000

Message 2: Linguistic Olympics update

Date: Wed, 10 May 2000 18:42:41 -0700
From: Tom Payne <tpayneOREGON.UOREGON.EDU>
Subject: Linguistic Olympics update

Thank you very much to those who have looked at the Linguistic
Olympics website and given me suggestions on how to improve it. I
neglected to mention in my posting yesterday that I very much
appreciate comments on the individual problems from those who are
familiar with the languages involved. I cannot do all the background
research on these languages myself, and so I rely on the support of
the community of linguists to check on the accuracy of the information
presented in the problems. This is an educational outreach that
represents the whole field of linguistics and so I want the
information to be absolutely accurate.

Just as a reminder, the site is found at Some systems
may require you to type

Thank you again for your comments and suggestions. And I do look
forward to receiving many more linguistic problems.
