Workshop: Semantic Approaches to Binding Theory

organized as part of the
European Summer School on Logic, Language and Information (ESSLLI 2004)
16-20 August, 2004 in Nancy

Workshop Organizers:
Ed Keenan, UCLA (ekeenan@ucla.edu)
Philippe Schlenker, UCLA & IJN (schlenke@ucla.edu)

Workshop Purpose:

Binding Theory, which is concerned with sentence-internal constraints on
anaphora, was originally conceived in syntactic terms as a set of
conditions on the distribution of indices (Chomsky 1983). Thus Condition A
stated that anaphors are locally bound (*John/i thinks that himself/i is
clever); Condition B stated that Pronominals are locally free (*He/i likes
him/i), and Condition C required that R-expressions be free (*He/i thinks
that John/i is clever). But other researchers have attempted to derive these
constraints from lexical semantics or the interpretative procedure rather
than the syntax. Some add a semantic component to a syntactic core
(e.g. Reinhart 1983, Heim 1993, Fox 2000, Buring 2002), but others are more
radically semantic (e.g. works by Jacobson, Keenan, Barker & Shan, Butler).

The workshop, which is intended for advanced PhD students and researchers,
will provide a forum to compare and assess these diverse proposals. We
welcome proposals for 45mn contributions (30mn presentation + 15mn
discussion), which should be specific, explicit and semantically informed.
We list below some possible topics, though the list is not exhaustive.

Possible Workshop Topics:
-Semantic analyses of standard Binding Conditions
-Arguments pro or contra semantic approaches to Binding Theory
-Relation between logophors and anaphors
-Relation between deixis and anaphora
-Cross-linguistic variation in binding conditions

OntoLex 2004:
Ontologies and Lexical Resources
in Distributed Environments


Centro Cultural de Belem
LISBON, Portugal
29th may 2004

In Association with

Main conference 26-27-28 May 2004

Motivations and aim

The use of ontological knowledge in language technology applications goes a
long way back. Recently, however, the project of turning the World Wide Web
into a machine understandable resource to access digital information (the
so-called Semantic Web) has stimulated a renewed interest in ontologies. In
several recent workshops and conferences, researchers have investigated
their nature and application potential for knowledge management,
information retrieval and extraction, information exchange in agent-based
systems as well as dialogue systems. Attention is being drawn to new
aspects of ontology research such as ontology coordination and mapping
aspects that are particularly relevant for distributed environments such as
Knowledge Grid and Semantic web. In fact the annotation of web resources in
agreement with concepts and relations as defined in ontologies, is useful
for establishing a conceptual support for knowledge communication.

  From this perspective, lexicographers, lexical semanticists and
ontologists are joining forces to build innovative systems for integrating
ontological knowledge with lexical and semantic resources. Important
examples of this interaction are the recent works on the conceptual
analysis of WordNet (one of the first lexical knowledge bases), and the
wide use of upper ontologies in innovative international projects like
EuroWordNet, SIMPLE, Balkanet, DWDSnet. WordNet was designed and built
entirely by psychologists, linguists, and lexicographers. Nevertheless,
there are obvious parallels with ontologies, especially in the kinds of
structuring relations used (taxonomical links, meronymy or part-of, etc.),
and indeed WordNet has for years attracted the attention of philosophers
and ontologists. In this context, the distinction between conceptual
(possibly axiomatic) ontologies and lexical ontologies (which contain both
linguistic and ontological information) has become more and more central in
the field.

In this workshop we want to discuss ontologies as resources per se, as well
as for what concerns the relation between ontological knowledge and
language. This relation can be investigated from a number of different
angles, for example what differences and similarities there are between
ontologies and more traditional lexical resources such as dictionaries and
wordnets; how ontologies can be extracted from language corpora; what role
language plays in the definition and mapping of ontologies; and finally,
how ontologies can be used to treat language in language technology
applications in particular applications for distributed environments.

Topics to be addressed in the workshop include, but are not limited
Design principles and methodologies for upper-level ontologies and
semantic lexical resources
Evaluation, comparison, mapping and integration of ontologies and lexical
resources Applications of ontologies and semantic lexical resources in
LT applications (e.g. QA, Information Retrieval, Information Extraction,
Machine Translation)

Role of semantic lexical resources in ontology learning
Methods to derive ontological knowledge from text
Methods to annotate text with reference to an ontology
Ontology-based query expansion techniques
Ontologies and multi-lingual lexical resources
Ontologies and ontology mapping in multi-lingual applications
Ontologies and lexical resources for meaning negotiation

Two discussions will be organised around the following topics:
Filling the gap between axiomatic and linguistic ontologies
The role of lexical resources in the Semantic Web and the Knowledge Grid

Reasons of interest
A new scientific community is growing around this largely interdisciplinary
area: following the spirit of the previous two OntoLex workshops, this
workshop aims at being an important meeting point for researchers involved
in the fields of lexical resources and ontologies, favouring the exchange
of scientific experiences and proposing new directions of inquiry. This
year, the workshop particularly welcomes contributions from researchers
that are investigating the application of ontologies and lexical resources
in distributed environments such as Knowledge Grid and Semantic Web.
