 Treebanks and Linguistic Theories 2002
 20th and 21st September 2002, Sozopol, Bulgaria

Workshop motivation and aims

Treebanks are a language resource that provides annotations of natural
languages at various levels of structure: at the word level, the
phrase level, the sentence level, and sometimes also at the level of
function-argument structure. Treebanks have become crucially
important for the development of data-driven approaches to natural
language processing, human language technologies, grammar extraction
and linguistic research in general. There are a number of on-going
projects on compilation of representative treebanks for languages that
still lack them (Spanish, Bulgarian, Portugese,Turkish) and a number
of on-going projects on compilation of treebanks for specific purposes
for languages that already have them (English).

The practices of building syntactically processed corpora have proved
that aiming at more detailed description of the data becomes more and
more theory-dependent (Prague Dependency Treebank and other
dependency-based treebanks as the Italian treebank (TUT) or the
Turkish treebank (METU); Verbmobil HPSG Treebanks, Polish HPSG
Treebank, Bulgarian HPSG-based Treebank etc.). Therefore the
development of treebanks and formal linguistic theories need to be
more tightly connected in order to ensure the necessary information
flow between them.

The workshop aims at being a forum for researchers and advanced
students working in one or both of these areas. It will be held in
conjunction with the summer school "Empirical Linguistics and Natural
Language Processing", Flagman hotel, Sozopol, Bulgaria.

Topics of interest

Papers should address the following topics:

- design principles and annotation schemes for treebanks;
- applications of treebanks in acquiring linguistic knowledge and NLP;
- the role of the linguistic theories in a treebank development;
- treebanks as a base for linguistic research;
- evaluation of treebanks;
- tools for creation and management of treebanks;
- standards for treebanks.

Two round-table discussions will be organized on the following topics: 

- the relationship between the syntactic properties of a given
language and the choice of linguistic theory for annotation purposes

- the utility of treebanks for linguistic theorizing

 *** International CLASS Workshop ***


 Natural, Intelligent and Effective Interaction in
 Multimodal Dialogue Systems

 Copenhagen, Denmark
 28-29 June 2002

 Detailed and more up to date information
 may be found at the workshop webpage:

Invited Speakers/Contributors (nearly all confirmed):

Tim Bickmore and Justine Cassell (MIT Media Lab), Phil Cohen (Oregon
Graduate Institute), Ronald Cole (University of Colorado at Boulder),

Following up on the CLASS workshop in Verona (Italy, 14-15 December
2001), this workshop will concentrate on innovative and challenging
approaches on natural, intelligent and effective interaction in
multimodal dialogue systems. The aim of the workshop is to bring
together theoretically and practically oriented researchers from both
academia and industry with the purpose of having a thorough, fruitful
and representative discussion of the topic area in an international


The workshop is sponsored by the European CLASS project
( which was initiated on the request of the
European Commission with the purpose of supporting and stimulating
collaboration within and among Human Language Technology (HLT)
projects, as well as between HLT projects and relevant projects
outside Europe. Currently, CLASS comprises 42 projects and 220
registered members.


We welcome papers describing theoretical or practical research on
multimodal dialogue systems. The focus of the workshop is on natural,
intelligent and effective multimodal interaction. Topics of interest

* Multimodal Signal Processing
 Models for multimodal signal recognition and synthesis,
 including combinations of speech (emotional speech and
 meaningful intonation for speech), text, graphics, music,
 gesture, face and facial expression, and (embodied)
 animated or anthropomorphic conversational agents.

* Multimodal Communication Management
 Dialogue management models for mixed initiative
 conversational and user-adaptive natural and multimodal
 interaction, including models for collaboration and multi-
 party conversation.

* Multimodal Miscommunication Management
 Multimodal strategies for handling or preventing
 miscommunication, in particular multimodal repair and
 correction strategies, clarification strategies for
 ambiguous or conflicting multimodal information, and
 multimodal grounding and feedback strategies.

* Multimodal Interpretation and Response Planning
 Interpretation and response planning on the basis of
 multimodal dialogue context, including (context-semantic)
 models for the common representation of multimodal
 content, as well as innovative concepts/technologies on
 the relation between multimodal interpretation and

* Reasoning in Intelligent Multimodal Dialogue Systems
 Non-monotonic reasoning techniques required for
 intelligent interaction in various types of multimodal
 dialogue systems, including techniques needed for
 multimodal input interpretation, for reasoning about the
 user(s), and for the coordination and integration of
 multimodal input and output.

* Choice and Coordination of Media and Modalities
 Diagnostic tools and technologies for choosing the
 appropriate media and input and output modalities for the
 application and task under consideration, as well as
 theories and technologies for natural and effective
 multimodal response presentation.

* Multimodal Corpora, Tools and Schemes
 Training corpora, testsuites and benchmarks for multimodal
 dialogue systems, including corpus tools and schemes
 for multilevel and multimodal coding and annotation.

* Architectures for Multimodal Dialogue Systems
 New architectures for multimodal interpretation and
 response planning, including issues of reusability and
 portability, as well as architectures for the next
 generation of multi-party conversational interfaces to
 distributed information.

* Evaluation of Multimodal Dialogue Systems
 Current practice and problematic issues in the
 standardization of subjective and objective multimodal
 evaluation metrics, including evaluation models allowing
 for adequate task fulfilment measurements, comparative
 judgements across different domain tasks, as well as
 models showing how evaluation translates into targeted,
 component-wise improvements of systems and aspects.


Although the workshop has an open character implying that plenty of
room is available for the presentation of papers from researchers from
all over the world, the workshop will contain invited contributions
from a group of 10 specially qualified researchers with a balanced
composition of workshop-relevant expertise. Part of the group is
selected from the broad CLASS community; part of them are
internationally leading researchers from outside CLASS. Invited
contributors will also participate in the panel session organized by
the co-chairs of the workshop program committee.


In addition to papers for full plenary presentation, we encourage the
submission of short papers in combination with a very short
presentation in the plenary session followed by a poster
presentation. Full papers must be no longer than 10 pages, including
references, examples, algorithms, graphical representations,
etc. Short papers should be 4 pages maximally.

Full and short papers should be sent electronically to the e-mail
address and must be received no
later than 31 March 2002.

Stylefiles are available at the workshop webpage:
Papers should be submitted in pdf or postscript format.

The title page should include the following information (no separate
title page is needed):

- Title
- Authors' names, affiliations, and email addresses
- Abstract (up to 15 lines)
- List of relevant keywords


Submission of full and short papers: 31 March 2002
Notification of acceptance: 30 April 2002
Final submissions: 31 May 2002
Workshop: 28-29 June 2002


Full papers and short papers will be published in the workshop

In addition to the group of invited contributors, authors of a
selected number of papers accepted for the workshop proceedings will
be asked to send in an extended and updated version of their paper for
publication in a book that will be published by Kluwer Academic
Publishers (TLTB book series). In order to guarantee full coherence of
the book, we might invite some workshop-external researchers to
contribute a chapter to the book as well.


In addition to the presentation of full and short papers in the
plenary session, we will organize the following panel discussion on
the main theme of the workshop:

 Natural Multimodal Interaction: Current Practice and
 Future Research

Members of this panel session will be invited contributors. Panellists
will be asked to send in a short position abstract before the
workshop. After the workshop, a written summary of this panel session
will be available at the CLASS sub-website on Natural and Multimodal
Interactivity ( We intend to make
available a video or audio recording as well.

Further, we strongly encourage proposals for a second panel session
related to the main topic of the workshop or some special
subtopic. The deadline for panel session proposals is 30 April
2002. Proposals can also be sent to the workshop e-mail address
( and should contain the
following information:

- title of the proposed panel session
- a brief description of the suggested topic of the panel
 session, including an explanation of why this topic is
 relevant for the field
- a list of suggested panellists

Questions on panel session proposals may be directed to the chairs of
the workshop program committee at
