THE ESSLLI'96 STUDENT SESSION
CALL FOR PAPERS
Deadline: May 31st

A novelty at ESSLLI'96 is the student session. The purpose of
the student session is to provide students with an opportunity
to present their work in progress and get valuable feedback by
senior researchers and "colleague-students".

To that end, students are encouraged to submit papers describing
*work in progress* (so as to benefit most from feedback). The emphasis
will be on papers that show creativity, innovative ideas and promise
rather than on papers that present well-polished results.

The student session has been designated its own timeslot in the
schedule of ESSLLI'96. Such basically means that there will be
a 90-minutes student session EVERY DAY. Depending on the number
and quality of submitted papers, either only in the first
week or in both weeks. The session will not be a poster session!
Students will be presenting their work in a 20+10 minutes talk.

The areas of interest are essentially the areas of the summer
school: Logic, Language, Computation, Logic & Language, Logic &
Computation, and Language & Computation. A comprehensive but surely
not complete list of topics:

LOGIC
intuitionistic logic, many-valued logic,
fuzzy logic, quantification logic, logic and uncertainty,
logic of action, BDI logics, process logics, abduction, non-monotonic
reasoning, modal logic, temporal logic, mathematical foundations of
computer science, dynamic logic, model theory ......

LANGUAGE
syntax, semantics, pragmatics, phonology, morphology, phonetics,
topic-focus structure, discourse, contextual reference,
quantification, presupposition, thematic relations, rhetorical
relations ....

COMPUTATION
concurrent systems, intelligent agents, multi-agent worlds, genetic
algorithms, computer-aided education, neural networks, planning,
probabilistic reasoning, qualitative reasoning, theorem proving,
constraint-based reasoning ....

LOGIC & COMPUTATION
abductive/deductive/inductive logic programming, finite model theory,
belief revision, cognitive modeling, common sense reasoning,
computational complexity, constraint satisfaction, knowledge acquisition,
knowledge representation ......

LOGIC & LANGUAGE
update semantics, dependency, dynamic semantics, formal semantics,
event-based semantics, intensionality, property theory, self-reference ....

LANGUAGE & COMPUTATION
connectionism, PDP-NLP, lexica, corpora, information retrieval,
statistical & probabilistical approaches to NLP, speech recognition,
speech generation, dialogue systems, comutational grammar formalisms,
parsing, machine learning of natural language, natural language
interfaces, integrating language and vision, machine translation .....

Submissions should not be longer than 5 pages, including references and
abstract but excluding a title page with the addresses of the authors
so as to facilitate anonymous reviewing. The 'stylesheet' for submissions
is: Font Times Roman 12pt, margins 1 inch all around, 1.5 line-spacing,
no columns.


Electronic submissions are highly encouraged, and should have arrived
with the program chair at Friday May 31st at 12am CET. Please, do send

Subject: Query: German Grammar Checking Feasibility
Date: 19 Apr 1996 13:25:23 GMT
To: s61...@compute.tfh-berlin.de

I am currently working on a project to try and develop a system for checking
german texts for mistakes using a computer.

What I would like to know is:

Does anyone believe that it is possible to check the grammar in a piece of
german text without an understanding of what the sentence is supposed to
mean/say?

Personally, I don't believe this is possible, or rather that the quality of a
given check will increase in proportion to the amount of knowledge the computer
has over the world described in the text (which may not be necessarily a 'real'
world) and the computer's understanding of what the text is trying to say about
that world.

Currently I am playing with the idea of pairing nouns, verbs, etc... with the
sort of ideas they are used to express, for example:

eindringen => in + akk. = things the subject(s) can force its/their way into
subjekt = people, gas, water...
auf + jemandem

Obviously this is far too much information to store, represent and, just as
importantly, access quickly (the system should be interactive) given that I do
not wish to simply work on a tiny specialist subset of the german language.
However at this stage I am keeping things at a fairly high-level, with no fixed
model for representing the information I require.

I look forward to hearing any ideas anyone has about this. I will (eventually)
re-post this in German (I'm english and so any mistakes I make could be
embarrasing given the topic!) and will welcome any replies written in german. I
have little formal knowledge of natural language processing and would
appreciate any explanations of any jargon used.

Thanks.

WORKSHOP ON ROBUST PARSING - CALL FOR PAPERS
August 12 - 16, 1996

at ESSLLI'96
European Summer School in Logic, Language and Information
Prague, Czech Republic

BACKGROUND:
Parsing systems able to analyse natural language text robustly and
accurately at an appropriate level of detail would be of great value in
computer applications ranging from speech synthesis and document style
checking to message understanding and automatic translation. A number of
research groups worldwide are currently developing such systems, varying
in the depth of analysis from lexical parsing or tagging (identifying
syntactic features just of individual words), through shallow or phrasal
parsing (forming hierarchical syntactic structure but not exploiting
subcategorisation), to full parsers (which deal with unbounded
dependencies etc., and are able to recover predicate-argument structure).

To bring researchers in this area together to present and compare
state-of-the-art systems for robust parsing, a workshop will be held
August 12-16, 1996, during the first week of ESSLLI'96, the European
Summer School in Logic, Language and Information.

We invite the submission of papers describing implemented robust parsing
systems; also evaluations, comparisons, and critiques of different parsing
systems or technologies. The main aim of the workshop is to identify the
strengths and weaknesses in the diverse set of approaches currently being
investigated, and to discuss areas that require further work.

To facilitate comparison between systems, authors of accepted papers will
be supplied with a small corpus of 30 sentences and encouraged to run
these through their systems, using simple (supplied) criteria to evaluate
the results.

WORKSHOP STRUCTURE:
The workshop will consist of 5 90-minute sessions, with two papers in each
session. Please note that speakers will be expected to register for ESSLLI
(thus being eligible to attend all other workshops, as well as the many
courses and symposia). There is a small amount of money available to go
towards the expenses of those who have no other source of funding.

ORGANISERS:
John Carroll, University of Sussex
and Ted Briscoe, University of Cambridge

SUBMISSION DETAILS:
Authors should submit an extended abstract (2000-3000 words) either
electronically or as hard-copy. Electronic submissions must be either
plain ascii text or a single latex file. Your e-mail address should appear
on your paper, and unless requested otherwise, all further correspondence
will be conducted via e-mail.

Call for Participation

LOGIC COURSE ON THE INTERNET: DYNAMIC SEMANTICS

The Institute for Logic, Language and Computation (Amsterdam) and the Dutch
Graduate School in Logic hereby announce the first of a planned series of
courses on the internet.

This first course is one on dynamic semantics, a discipline in the
semantics of natural language in which interpretation is conceived of as a
process essentially tied to change of information. The course is given by
Paul Dekker and David Beaver (both ILLC, Amsterdam). Additional
coordination by Erik-Jan van der Linden (also ILLC).

The course is meant for PhD students and advanced undergraduates who are
familiar with basic notions of logic and model-theoretic semantics.

Distinctive feature of this course is that it is held on the world wide
web. All communication (including an electronic classroom, readers,
collaboration on exercises etc.) takes place at the internet.

The course is given from May 3 to July 12. The course offers room for a
limited number (20) of participants, but it can also be followed by
observers who are professionally interested in the experiment. People who
are interested are adviced to subscribe soon. By following the course the
students can earn official credits (10 ECTS credits).

For more information on the course and on how to subscribe (both as a
participant and as an observer), the interested reader is referred to the

Final Call for Participation

Multilinguality in the Software Industry:
The AI Contribution
(MULSAIC'96)

August 12, 1996, Budapest, Hungary
In conjunction with the ECAI'96 conference
(August 12 - 16, 1996)

WWW: http://www.iit.nrcps.ariadne-t.gr/~costass/mulsaic.html


Workshop Objectives

The objective of the workshop is to bring together people from the software
industry and the AI research community. In this way, it will provide an
opportunity for people from the software industry to present particular
problems and questions associated with multilinguality as well as an
opportunity for AI researchers to show that AI-based methods and tools can
help to find solutions and answers.

Workshop Background

The ability to develop products which can be adapted to the language and
culture of local markets is a prerequisite for software companies wishing
to be active internationally. This process, often known as Localisation,
has become an important and increasingly sophisticated part of the overall
development process. AI-based methods and tools can be used in the software
industry to build such multilingual software. AI contribution concerns not
only the use of AI in the software engineering process but also the
embedding of AI modules in the end products.

AI-based methods and tools have the potential to enhance the intrinsic
capability of products in a number of different application areas. For
example, they can be used to improve processes such as multilingual
information retrieval, multilingual generation of messages and
documentation, software translation.

Information retrieval and browsing systems of the future will need to be
knowledge-based. They will use knowledge representation techniques to
organise information in language-independent knowledge bases, make useful
associations and identify important information. Message generation systems
will use knowledge representation techniques to organise the software
knowledge in language-independent knowledge bases as well as natural
language generation techniques to generate messages on-line in the end-user
language. Automatic generation of documentation in more than one languages
will also be possible using knowledge representation and natural language
generation techniques. Knowledge representation techniques will be used for
the development of intelligent translation tools such as multilingual
terminological knowledge bases and translation memories, in order to
facilitate translation of software and documentation. Multilingual language
resources, such as lexica, grammars and morphological modules will be added
to software applications in order to improve functions such as spelling and
syntax checking in more than one languages.

Workshop Organisation

This workshop is structured around the following sessions:
- Software companies experiences concerning multilinguality.
Two large software companies will present their experiences in the subject.
- Multilingual information services.
Cross-lingual information retrieval on the WWW, distributed multilingual
information retrieval, multilingual network-based information services
are among the topics that will be discussed in this session.
- Multilingual resources and intelligent translation tools.
Automatic extraction of bilingual lexical equivalences from parallel
corpora, extraction of example phrases for bilingual dictionaries,
Example Based Machine Translation of Software Documentation, lingustic
considerations for multilingual software manuals are among the topics
that will be discussed in this session.
- Multilingual generation of messages and documentation.
Messages and documentation generation systems that use knowledge
representation and natural language generation techniques to generate
multilingual mesages and documentation respectively will be discussed here.
- Summarisation and a general discussion.

{\it The IJCAI Workshop on Connectionist-Symbolic Integration: From
Unified to Hybrid Approaches} was held for two days
during August 19-20 in Montreal, Canada, in conjunction with the
Fourteenth International Joint Conference on Artificial Intelligence(IJCAI'95).
The workshop was co-chaired by Ron Sun and Frederic Alexandre.
During the two days of the workshop, various presentations and discussions
brought to light many new ideas, controversies, and syntheses.
The focus was on learning and architectures that feature hybrid representations
and support hybrid learning.

Hybrid models involve a variety of different types of processes and
representations, in both learning and performance.
Therefore, multiple mechanisms interact in complex ways in most models.
We need to consider seriously ways of structuring these different components,
which thus occupy a clearly more prominent place in this area of research.
The hybridization of connectionist and symbolic models also
inherits the difficulty with learning from the symbolic
side, and mitigates to some large extent the advantage that the purely
connectionist models have in their learning abilities.
Considering the importance of learning, in both modeling cognition and
building intelligent systems, it is crucial for researchers in this area
to pay more attention to ways of enhancing hybrid models
in this regard and to putting learning back into hybrid models.
