SECOND CALL FOR PAPERS

Journal of Natural Language Engineering

Special Issue on PARALLEL TEXTS

Guest Editors: Rada Mihalcea, University of North Texas Michel Simard, Xerox Research Centre Europe

http://www.cs.unt.edu/~rada/jnle

OBJECTIVE OF THIS SPECIAL ISSUE

Parallel texts have become a vital resources for efficiently deriving many multi-lingual text processing tools. This special issue is devoted to advances in building and using parallel corpora. We invite papers on all topics related to parallel texts, including but not limited to:

The collection, organization and processing of parallel corpora: - Identifying and harvesting parallel texts from the Web and other large collections - Evaluating the quality of parallel corpora (e.g. detecting omissions and gaps, translation errors or inconsistencies, etc.) - Sentence-, phrase- and word-level alignment - Alignment evaluation metrics and methods

Active uses of parallel corpora for: - Building multilingual lexical resources - Deriving language processing tools and resources for new languages - Annotating corpora (e.g. word-sense disambiguation) - Machine translation (e.g. statistical and example-based MT) - Machine-assisted translation (e.g. translation memories and interactive MT) - Cross-linguistic information retrieval and information extraction

While we invite submissions addressing any of the above topics, or related issues, we particularly welcome work involving parallel corpora addressing languages with scarce resources.

SUBMISSION FORMAT

We are expecting full papers to describe original, previously unpublished research, addressing issues related to the construction and use of parallel texts.

Papers should be formatted according to the NLE journal instructions, and should not exceed 15 pages. The preferred formatting system is LaTeX, which can be used for direct typesetting, and a style file is available through anonymous ftp from the following address: ftp.cup.cam.ac.uk/pub/texarchive/journals/latex/nle-sty/. In case of difficulty there is a helpline available on e-mail: texlinecup.cam.ac.uk.

Send your submission (a PostScript or PDF file), prepared for anonymous review, to both: Rada Mihalcea, University of North Texas, radacs.unt.edu and Michel Simard, Xerox Research Centre Europe, Michel.Simardxrce.xerox.com

IMPORTANT DATES

Paper submissions: May 1, 2004 Notification of acceptance: August 30, 2004 Final versions due: November 30, 2004 Journal publication: June, 2005

ABOUT THE JOURNAL

Natural Language Engineering is an international journal designed to meet the needs of professionals and researchers working in all areas of computerized language processing, whether from the perspective of theoretical or descriptive linguistics, lexicology, computer science or engineering. Its principal aim is to bridge the gap between traditional computational linguistics research and the implementation of practical applications with potential real-world use. As well as publishing research articles on a broad range of topics from text analysis, machine translation and speech generation and synthesis to integrated systems and multi modal interfaces the journal also publishes book reviews. Its aim is to provide the essential link between industry and the academic community.

Natural Language Engineering encourages papers reporting research with a clear potential for practical application. Theoretical papers that consider techniques in sufficient detail to provide for practical implementation are also welcomed, as are shorter reports of on-going research, conference reports, comparative discussions of NLE products, and policy-oriented papers examining e.g. funding programs or market opportunities. All contributions are peer reviewed.

Ontology Learning and Population: Towards Evaluation of Text-based Methods in the Semantic Web and Knowledge Discovery Life Cycle

Date: 22-Aug-2004 - 23-Aug-2004 Location: Valencia, Spain Contact: Paul Buitelaar Contact Email: paulbdfki.de Meeting URL: http://olp.dfki.de/ecai04/cfp.htm

Call Deadline: 15-Apr-2004

Meeting Description:

Automatic methods for text-based ontology learning and population have developed over recent years (e.g. results from the ECAI-2000, IJCAI-2001, ECAI-2002 workshops on Ontology Learning and the KCAP-2001, ECAI-2002, KCAP-2003 workshops on Knowledge Markup / Ontology Population), but a remaining challenge is to evaluate in a quantitative manner how useful or accurate the extracted ontology classes, properties and instances are. In fact, this is a central issue as it is currently very hard to compare methods and approaches, due to the lack of a shared understanding of the task at hand. The core theme of the workshop therefore will be to develop such a shared understanding through the definition of a clear task (and corresponding sub-tasks), identify resources needed for the task/sub-tasks and to discuss how best to develop an open source evaluation platform.

ECAI-2004 Workshop on Ontology Learning and Population: Towards Evaluation of Text-based Methods in the Semantic Web and Knowledge Discovery Life Cycle

16th European Conference on Artificial Intelligence August 22nd/23rd 2004 Valencia, Spain

http://olp.dfki.de/ecai04/cfp.htm

With Support From: KnowledgeWeb (http://knowledgeweb.semanticweb.org/)

Topic and Motivation Ontologies are formal, explicit specifications of shared conceptualizations, representing concepts and their relations that are relevant for a given domain of discourse. Currently, ontologies are mostly developed (including ontology construction, extension, mapping and merging) as well as used (ontology population through knowledge markup) by a manual process, which is very ineffective and may cause major barriers to their large-scale use in such areas as Knowledge Discovery and Semantic Web. The expected central role of ontologies in the organization and functioning of the Semantic Web has been well documented in recent years. Somewhat less traditional is the role of ontologies in incremental approaches to Knowledge Discovery, in which ontologies and machine learning methods are used in combination to mine, interpret and (re-)organize knowledge.

As human language is a primary mode of knowledge transfer, linguistic analysis of relevant documents for ontology learning and population seems a viable option. More precisely, automation of these tasks can be implemented by a combined use of linguistic analysis and machine learning approaches for text mining. The workshop will therefore be concerned with reports on the development of such methods, but specifically also with the quantitative evaluation of these methods.

Automatic methods for text-based ontology learning and population have developed over recent years (e.g. results from the ECAI-2000, IJCAI-2001, ECAI-2002 workshops on Ontology Learning and the KCAP-2001, ECAI-2002, KCAP-2003 workshops on Knowledge Markup / Ontology Population), but a remaining challenge is to evaluate in a quantitative manner how useful or accurate the extracted ontology classes, properties and instances are. In fact, this is a central issue as it is currently very hard to compare methods and approaches, due to the lack of a shared understanding of the task at hand. The core theme of the workshop therefore will be to develop such a shared understanding through the definition of a clear task (and corresponding sub-tasks), identify resources needed for the task/sub-tasks and to discuss how best to develop an open source evaluation platform.

Areas of Interest Submissions are invited on these topics in Ontology Learning and Population (OLP):

* Evaluation Methodologies and Metrics for OLP - Including Experience and Best Practice from Related Evaluation Efforts in the Context of CLEF, TREC, SENSEVAL, etc. * Datasets and Resources for the Evaluation of OLP * Definition of Sub-Tasks for OLP - Extraction of Taxonomy, Class-hierarchy - Extraction of Class-properties, Relations - Extraction of Class-instances, Individuals * Definition of Related Tasks - Ontology Extension, Evolution - Ontology Mapping - Ontology Merging * Text-based Approaches for OLP, for instance (Combinations of): - NLP and Linguistic Analysis for OLP - (NLP-based) Text-mining for OLP - (Ontology-aware) Information Extraction for OLP * OLP in the Context of the Semantic Web * OLP in the Context of Knowledge Discovery

Workshop Schedule This will be a one-day workshop with a proposed schedule of 2 or 3 paper sessions and a poster session. The workshop will include a round-table working session on the topic of evaluation of ontology learning and population. It is expected that the outcome of this discussion will lead to a written report on guidelines for setting up an evaluation platform for these tasks.
