Message 1: Extended Deadline! LEXICAL SEMANTICS IN CONTEXT: CORPUS, INFERENCE AND DISCOURSE

Subject: Extended Deadline! LEXICAL SEMANTICS IN CONTEXT: CORPUS, INFERENCE AND DISCOURSE



 ESSLLI-98 Workshop on 
 LEXICAL SEMANTICS IN CONTEXT: CORPUS, INFERENCE AND DISCOURSE
 August 17 - 21, 1998

 A workshop held as part of the 
 10th European Summer School in Logic, Language and Information 
 (ESSLLI-98) 
 August 17 - 28, 1998, Saarbruecken, Germany

 ** LAST CALL FOR PAPERS **

 ** EXTENDED DEADLINE : March 2, 1998 **


ORGANIZERS: Johan Bos (Saarbruecken) and Paul Buitelaar (Brandeis University)


The workshop aims at bringing together research in two complementary fields of 
semantic analysis that are still too far apart. In order to achieve both a 
broad and a deep understanding of any given text document, a system needs both 
advanced acquisition of corpus specific lexical semantic knowledge and powerful 
inference mechanisms that utilize that knowledge in discourse analysis.

Given the still relatively limited results within both areas there has been 
little impetus to combine them. Corpus-based extraction of lexical semantic 
knowledge has only recently become a more feasible task, because of the growing
availibility of on-line text documents; robust corpus processing technologies, 
such as broad coverage part-of-speech tagging and shallow parsing; and readily 
available statistical methods. The various approaches to discourse analysis, 
originating in such diverse fields as formal semantics, psychology and AI, are 
in the process of converging into a unified approach to the analysis and 
representation of the cohesive structure of natural language documents.

The intersection between these two fields lies in the application of lexical 
semantic knowledge to such problems in discourse analysis as anaphora 
resolution and discourse segmentation. In fact, the benefit will be mutual, 
because knowledge of discourse structure is helpful to lexical knowledge 
extraction as well. 

In summary, large scale domain specific lexical semantic knowledge acquisition 
can assist in analyzing discourse structures, which in turn can assist in 
acquiring even more accurate lexical semantic representations for the relevant 
terms in the domain.

Message 2: CFP: SIGPHON Meeting at COLING/ACL 98

 The Computation of Phonological Constraints
 ===========================================

 The 4th Meeting of the ACL
 Special Interest Group in Phonology
 (http://www.cogsci.ed.ac.uk/~sigphon/98)

 In conjunction with
 The COLING-ACL'98 Joint Conference
 Montreal, Canada, 15th August 1998


The Meeting
- ---------
Constraint-based theories of phonology have become enormously popular
in recent years. Such theories express generalizations by stating how
and when a language's phonological forms are constrained, rather than
relying on rules that actively modify the forms.

Computational ideas have often provided an impetus for these
innovations. Koskenniemi's (1983) 2-level morphophonological processor
introduced parallel constraining relations as an alternative to an
ordered system of rewrite rules. Declarative Phonology (c 1990)
focusses on the unity of representations and rules as constraints,
drawing on various computational ideas from unification to temporal
logic to finite-state calculi.

One current constraint-based theories is Optimality Theory (OT)
(Prince&Smolensky 1993). This theory found, at least partial,
inspiration in computational work by Smolensky on the relation between
symbolic and subsymbolic computation. Although this link with
connectionism has been left largely unexplored, OT has proved to be a
computationally productive theory, giving rise to several theoretical
papers on computational issues related to complexity and learnability,
as well as inspiring a number of implementations.

This workshop is designed to foster the link between computational
work and constraint-based phonology in general. To this end, it
invites submissions on topics related to the computation of any
constraint-based phonological formalism, including but not limited to
the three mentioned above. Here are some example topics:

 * the computational interpretation of phonological theories,
 * constraint ranking and interaction, eg. as in OT,
 * implementations of particular analyses,
 * results in the complexity of constraint application,
 * algorithms for learning constraints or constraint ranking,
 * results on the learnability of such constraints,
 * novel formalisms for constraint-based phonology,
 * representational issues raised by constraint-based approaches.

In short, papers are invited which address computational issues in
constraint-based theories of phonology.

Submission
- --------
 What: original research, not published elsewhere
 a completed study is prefered to proposals and progress reports
 originality, topicality and clarity will be the assessment criteria 
 How: submissions must be sent by email to sigphon98cogsci.ed.ac.uk 
 When: April 20 Submissions due
 May 22 Notification of acceptance
 June 23 Final (accepted) versions due


Submission Format
- ---------------
(Note that apart from the Medium and Length sections, these
requirements are as for submissions to COLING-ACL98.)
 Medium: postscript, emailed to sigphon98cogsci.ed.ac.uk
 please check postscript compatibility using either
 ghostview, or by printing the postscript file
 before sending
 Length: 10 pages maximum (including references and appendices)
 optional extra page for abstract in a second language
 Paper size: Please use A4 page-size
 Typesetting: LaTeX is encouraged, but not required.
 Layout: set margins so that text lies centred within a rectangle of
 6.5 x 9 inches (16.5 x 23 cm)
 Use Times Roman or Computer Modern font
 11 to 12 point for text
 14 to 16 point for headings and title
 centred page numbers in footers
 2 columns after title and abstract
 figures may range across columns

Since reviewing will be blind, a separate identification notice should
be emailed (in ASCII) to sigphon98cogsci.ed.ac.uk. It should include:
 title 
 author(s) name(s) 
 affiliation(s) 
 complete addresses 
 abstract in English
 submission to other conferences ('none' or list) 
 and author of record (for correspondence). 

Authors should not identify either themselves or their affiliations,
either directly or indirectly in the body of the text (the postscript
file).

Authors should use the COLING-ACL98 style files and templates for
preparing submissions (see http://coling-acl98.iro.umontreal.ca/Styles.html). 
This will help ensure that the layout requirements are met, and that
the effort required to format the final version will be minimized.


Registration
- ----------
Registration is open only to those registered for the main COLING/ACL
conference (see http://coling-acl98.iro.umontreal.ca/MainPage.html).
There will be an additional fee for the workshop (yet to be
determined). The 1997 ACL workshop fee was US$60.

ACL/EACL reserves the right to cancel any workshop if the number of
participants is below 25 persons.
