CALL FOR PAPERS

for the 1st International and

KI-08 Workshop on

ONTOLOGY-BASED INFORMATION EXTRACTION SYSTEMS (OBIES 2008)

23 September 2008, Kaiserslautern (Germany)

http://www.dfki.uni-kl.de/~adrian/workshops/obies2008

** Extended Paper submission deadline: June 22, 2008 **

OBJECTIVES

More and more information extraction (IE) systems use ontologies

for extraction tasks. These systems use knowledge representation

techniques for extracting information from lesser structured

domains more efficiently.

The advantages of these procedures are especially an increase of

quality in IE-templates, reusability, and maintainability.

Ontologies in IE may provide new techniques for supporting open

tasks of semantic analyses regarding for instance temporal

analyses, resolution of contradiction, or context awareness.

There are several open research topics about ontology-based

information extraction, for instance a proven architecture,

evaluation guidelines regarding the use of ontologies, or

ontologies vs. templates.

GOALS AND AUDIENCE

The workshop will be of major interest to researchers working on

information extraction, language technology and ontologies.

Furthermore, we expect that it will attract people working on

semantic web, question answering and other related fields.

TOPICS OF INTEREST

Suggested topics for contributions:

* Ontologies in templates, question answering, annotated corpora

or grammars

* Instance resolution (unification, disambiguation, and

recommendation)

* Relation resolution (extraction, recommendation, inference, and

validation)

* Using uncertainty in extraction tasks

* Evaluation and comparison of OBIE systems (corpora, metrics, etc.)

* OBIE as ontology population from texts

* Ontology-based text annotation as inverse of OBIE

* Using context models for improving IE performance (query, time,

user, etc.)

* RDF/OWL as knowledge representation formalism for NLP

* Integration of linguistic annotations and domain ontologies

SUBMISSIONS AND STYLE

Workshop submissions will be electronic, in pdf format only. Please

follow this link to EasyChair:

http://www.easychair.org/conferences/?conf=obies2008.

Papers must be written in English and should not exceed 8 pages in

Springer LNCS format. Please consult us, if this appears to be a

problem. At least one author of each accepted paper must register

for the workshop and present the contribution in order to be published

in the workshop proceedings. The OBIES 2008 organizers intend to

publish workshop papers online at http://CEUR-WS.org.

Those wishing to participate by providing a live system demonstration

or presenting an extended abstract or position paper should submit

a poster about 4 pages.
