2nd Workshop on Ontology Learning and Population: Bridging the Gap
between Text and Knowledge (OLP2)

Workshop at COLING/ACL 2006

http://olp.dfki.de/olp2/olp2_cfp.htm

July 22nd, 2006
Sydney, Australia

Supported By SmartWeb (http://www.smartweb-projekt.de/)

Topic and Motivation

An ontology is an explicit and formal specification of a shared
conceptualization of a domain of interest. Ontologies formalize the
intensional aspects of a domain, whereas the extensional part is
provided by a knowledge base that contains assertions about instances
of concepts and relations as defined by the ontology. The process of
defining and instantiating a knowledge base is referred to as
knowledge markup or ontology population, whereas (semi-)automatic
support in ontology development is usually referred to as ontology learning.

Ontologies have been broadly used in knowledge management
applications, including Semantic Web applications and research. In
recent years, ontologies have regained interest also within the NLP
community, specifically in such applications as information
extraction, text mining and question answering. However, as ontology
development is a tedious and costly process there has been an equally
growing interest in the automatic learning of ontologies. Much of
this work has been focused on textual data as human language is a
primary mode of knowledge transfer. In this way, textual data provide
both a resource for the ontology learning process as well as an
application medium for developed ontologies.

Automatic methods for text-based ontology learning and population
have developed over recent years, but it is difficult to compare
approaches and results. In the 1st Workshop on Ontology Learning and
Population (at ECAI 2004, Spain: http://olp.dfki.de/ecai04/cfp.htm)
we addressed this issue through an emphasis on the evaluation aspects
of the reported work. In the context of the 2nd workshop we intend to
continue this emphasis by providing a common data set for
participants to work with, consisting of an ontology and document
collection in the football (soccer) domain and a corresponding
automatically extracted knowledge base. Participants will be free to
use this or other data, but are encouraged to (also) use the OLP2
data set (http://www.dfki.de/sw-lt/olp2_dataset/) for their
experiments in order to better compare results with other participants.

An additional topic we intend to address at this workshop is the
relation between NLP and ontology development, the communities of
which are working on similar topics but using different terminology.
As this leads to a confound communication, the potential for
interdisciplinary work becomes much less pronounced. We therefore
intend the workshop to contribute to an enhanced interdisciplinary
understanding of tasks, methods and evaluations.

Areas of Interest

To provide a clear focus we request novel work on:

- Concept formation on the basis of text
- Learning concept hierarchies / non-taxonomic relations / rules /
axioms from text
- Named-Entity Recognition with respect to an ontology
- Ontology-based information extraction
- Ontology learning for IE, IR, MT, QA
- Gold standard and task-based evaluation of ontology learning, e.g.
in IE, IR, MT, QA
