This is the First Call for Papers for the


 "Integrating Information from Different Channels
 in Multi-Media-Contexts"

to be held as part of ESSLLI 2000 at Birmingham (UK), August 6-18, 2000


- ---------------------------------------------------------------------

In everyday situations agents must combine information from different
sources: Reference and predication can be based both on gestural and
spoken information. Inferences demand extracting information from
diagrams and the text built around them. Focus of attention is often
indicated by visual, gestural or acoustic means.

The growing number of researchers interested in multimodal information
reflects its practical relevance, not least in the construction of
man-machine interfaces. In order to model complex multimodal
information, a notion of composite signal is called for in which
the different "threads of information" are integrated. Understanding
composite signals may be necessary for all fields of science dealing
with information, whether empirically or formally oriented. Research
in this area is bound up with logical, linguistic, computational and
philosophical problems like

 - assessing the semantic contribution of information from
 different sources,
 - compositionality in the construction of information
 - extending the notions of reference, truth and entailment in
 order to capture the content of "mixed information states" and 
 - experimentally measuring the activity on different channels or 
 - investigating timing problems concerning "interleaving
 threads" of information.

Despite their foundational flavour, emerging theories in this area
have applications in domains as diverse as discourse analysis
(monitoring and back-channelling behaviour), styles of reasoning,
robotics (reference resolution by pointing) and Virtual Reality
(integration of gesture and speech).

Consequently, the workshop is addressed to scholars from different
fields: We welcome experimental researchers investigating
e.g. gesture, eye movement or other means of focussing in relation to
speech. At the same time workshop contributions of linguists,
logicians or computer scientists are invited who work on the
description and the formal modelling of complex signals. Finally, work
concerning the simulation of production or understanding of complex
signals, Virtual Reality type, neural net like or other, is also

Special Issue of Computational Linguistics: Anaphora and Ellipsis Resolution 

Guest editors: Ruslan Mitkov, Branimir Boguraev, Shalom Lappin

Anaphora and ellipsis both account for cohesion in text and are
phenomena of active study in formal and computational linguistics
alike. The correct interpretation of anaphora and ellipsis, as well
as the understanding of the relationship between them, is vital for
Natural Language Processing.

After considerable initial research, and after years of relative
silence in the early eighties, these issues have attracted the
attention of many researchers in the last 10 years and much promising
work on the topic has been reported. Discourse-orientated theories
and formalisms such as DRT and Centering have inspired new research on
the computational treatment of anaphora. The drive towards
corpus-based robust NLP solutions has further stimulated interest, for
alternative and/or data-enriched approaches. In addition,
application-driven research in areas such as automatic abstracting and
information extraction, has independently identified the importance of
(and boosted the research in) anaphora and coreference resolution.
Ellipsis resolution too, being of particular importance to a number of
Natural Language Understanding applications such as dialogue and
discourse processing, has received increasing attention. The growing
interest in anaphora and ellipsis resolution has been demonstrated
clearly over the last 4--5 years through the MUC coreference task
projects and at a number of related fora (workshops, conferences,

Against this background of expanding research and growing interest,
this special issue offers the opportunity for a high quality, and
timely, collection of papers on anaphora and ellipsis resolution.


The call for papers invites submissions of papers describing recent novel
and challenging work/results in anaphora and ellipsis resolution.
The range of topics to be covered will include, but will not be limited

 o new anaphora and ellipsis resolution algorithms,
 o factors in anaphora resolution: salience and interaction of factors,
 o techniques in ellipsis resolution,
 o use of theories and formalisms in anaphora resolution,
 o use of theories and formalisms in ellipsis resolution,
 o applications of anaphora/coreference resolution,
 o applications of ellipsis resolution,
 o multilingual anaphora resolution,
 o evaluation issues,
 o use/production of annotated corpora for anaphora and ellipsis.

In addition, we expect papers addressing various issues of debate related
to the resolution of anaphora and ellipsis, such as:

 o Is it possible to propose a core set of factors used in anaphora
 o When dealing with real data, is it at all possible to posit
 "constraints", or should all factors be regarded as "preferences"?
 o What is the case for languages other than English?
 o What degree of preference (weight) should be given to "preferential"
 factors? How should weights best be determined? What empirical
 data can be brought to bear on this?
 o What would be an optimal order for the application of multiple
 factors? Would this affect the scoring strategies used in selecting
 the antecedent?
 o Is it realistic to expect high precision over unrestricted texts?
 o Is it realistic to determine anaphoric links in corpora
 o Are all CL applications 'equal' with respect to their requirements
 from an anaphora resolution module? What kind(s) of compromises
 might be possible, depending on the NLP task, and how would
 awareness of these affect the tuning of a resolution algorithm for
 particular type(s) of input text?
 o Should ellipsis resolution be handled by syntactic or semantic
 o Is it necessary to retrieve both syntactic and semantic properties of
 the antecedent in the reconstructed representation of the elided

Finally, we invite discussion on various open questions from both
theoretical and computational point of view such as whether we should
construe ellipsis as entirely distinct from anaphora.
