 Call for papers


 Coling/ACL 98 workshop
 Discourse Relations and Discourse Markers

 August 15, 1998
 Universite de Montreal
 Montreal/Canada


The notion of discourse relation has received many interpretations, some 
of which are hardly compatible with one another. Nonetheless, there is a
consensus among researchers that intersegment relations hold between 
adjacent portions of a text and that these relations may be signalled by
linguistic means, including so-called cue phrases, aspect and mood shifts, 
theme inversions, and other markers. 

The workshop intends to bring together researchers working on discourse 
relations and discourse markers in different linguistic traditions and
different NLP applications. The particular focus of the workshop is 
the issue of discourse relations from the viewpoint of linguistic 
realization. Specifically, contributions should address one or more of 
the following questions:

* What are sound methodologies for comparing similar discourse markers
(contrastive studies, distribution analyses, etc.)?

* What are sound methodologies for relating discourse relations with
potential realizations?

* Are there discourse relations that are *always* lexically signalled?
Are there any that are *never* lexically signalled?

* What non-lexical (i.e., syntactic or prosodic) means are used to signal 
a relation? 

* In production, how does one decide whether to signal a relation at
all?

* In production, how does one motivate a choice among candidate signals
for a given relation?

* In production, how does the choice of signal interact with other
decisions (in particular, those of linearizing some tree or graph 
structure)?

* In analysis, is it possible to reliably infer discourse relations from 
surface cues?

* In analysis, how can one disambiguate polysemous signals such as 
"and", "since" (temporal or causal) etc.?

* What are useful lexical representations of discourse markers, for both
analysis and production?

* What are useful representations of discourse relations (and the entities 
they relate), such that they facilitate the realization decision? What 
features would one like to have handy in a representation so that choices 
can be made easily? 

* Are there significant differences between realizations in spoken and
written language?

* How do individual languages differ in terms of any of the above issues?
