This workshop aims to compare and contrast different ways of
modelling coherence in natural language generation and dialogue
in order to guide decisions such as:

- what is an appropriate response at a given point in a dialogue?
- what is the optimal ordering of propositions in a discourse?
- how should predicates, referring expressions and rhetorical
relations be realised (verbally and/or non-verbally) so that the
resulting utterance can be interpreted naturally and fluently?

The intention is to provide a forum for advanced PhD students
and researchers to present and discuss their work with
colleagues and researchers who work in the broad subject
areas represented at ESSLLI.


Approaches to coherence modelling can be broadly summarised
under three main headings: mentalistic, abstract/formal and
social/normative, which are described below. We welcome submissions
from graduate students or established researchers that focus on
generation tasks and either exemplify one of these approaches or
offer comparisons or constructive criticisms of one or more

Authors should make clear in their submissions:

- how they interpret the notion of ''coherence'' and how their work
contributes to a deeper understanding of this notion;
- the applicability of their work to generation tasks.

Possible topics are listed as bullet points below, but this
list is not intended to be exhaustive.

1. Mentalistic: modelling attentional states, intentions,
purpose etc, as in e.g. Grosz and Sidner, Cohen and
Levesque, Bunt, Ginzburg's QUD, Mann and Thompson's
Rhetorical Structure Theory:

- content selection on the basis of the preconditions
of the next turn (meaning and purpose)
- context dynamics and grounding
- local interactions, participants and particular situations
- intentions wrt dialogue plan and wrt collaboration
- how to combine multiple dialogue acts per utterance?

2. Abstract formal models: SDRT, Webber's D-LTAG, some interpretations
of Centering:

- textual coherence: consistency of syntactic resources
and thematic development of discourse thematic structure
+ focus shifting
- concept coherence: clear references- how often can
the same referring expression be repeated?
- generation via templates or grammar (fast or incremental)
- relevance
- consistency and truth maintenance.

3. Social/normative, using notions like obligation and commitment:
e.g. Traum and Poesio, Walton and Krabbe, Brandom:

- interaction management and dialogue control
- turn taking, feedback, clarification and repair
- obligations to address questions or to acknowledge assertions
- conditional obligations to execute directives
- commitments to defend an assertion if queried
- overt or implicit retraction of commitments
- sanctions for failure to meet commitments and obligations


Authors should submit abstracts of up to 2000 words in
PDF format to the email contact address given above.
The submissions will be reviewed by the workshop's programme
committee and additional reviewers. The accepted papers will
appear in the workshop proceedings published by ESSLLI. Final
versions may be up to 8 pages and must be formatted in LaTeX,
using style files which will be specified at the time of

Proceedings will also be published electronically by the
workshop organisers. We are in discussion with the editors of the
Journal for Logic, Language and Information (JoLLI) about the
possibility of publishing a selection of high-quality
papers from the workshop as a special issue, after a further
round of reviewing.


The workshop is part of ESSLLI and is open to all ESSLLI
participants. It will consist of five 90-minute sessions
held over five consecutive days in the second week
of ESSLLI. There will be 2 - 3 slots for paper presentation
and discussion per session. On the first day the workshop
organizers will give an introduction to the topic, followed
by a talk by our invited speaker.

All workshop participants including the presenters will be
required to register for ESSLLI. The registration fee for
authors presenting a paper will correspond to the early
student/workshop speaker registration fee. Moreover, a number
of additional fee waiver grants might be made available by
the local organizing committee on a competitive basis and
workshop participants are eligible to apply for those.

There will be no reimbursement for travel costs or accommodation.
Workshop speakers who have difficulty in finding funding
should contact the local organizing committee to ask for the
possibilities of a grant.
