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
