This is the fourth in the NLPXML series of workshops on natural language processing and XML. The first two workshops (NLPXML-2001 in Tokyo and NLPXML-2002 in Taipei) were primarily concerned with XML-based NLP tools and the use of XML in a wide range of NLP tasks. As XML rapidly became fully accepted within the NLP community, the theme of the third workshop (NLPXML- 2003 in Budapest) shifted to the new challenges and opportunities of the Semantic Web. The present workshop continues this theme by focusing on RDF/RDFS and OWL.
While "plain XML" has become the established standard for data representation, especially for purposes of interchange and software interoperability, the use of RDF (Resource Definition Framework), RDFS (RDF Schema) and OWL (Web Ontology Language) for NLP applications remains relatively limited. However, the combination of XML, RDF/RDFS and OWL provides an overall architecture for NLP resources of all kinds whose implications are still being worked out within the NLP community.
NLPXML-2004 provides a forum for presentation and discussion of practical applications of RDF, RDFS and OWL in NLP. The workshop is intended not only for those already using Semantic Web technologies, but also members of the NLP community who seek a fuller understanding of the motivations and implications of these standards for the field.
The workshop program is designed to move progressively from XML, via metadata and RDF, to ontologies and OWL, and finally to their combined use for NLP applications. In this way, the workshop aims to clarify the respective roles of XML, RDF/RDFS and OWL in language technology, in relation to the growth of the Semantic Web.

Techniques for text planning with XSLT
We describe an approach to text planning that uses the XSLT template-processing engine to create logical forms for an external surface realizer. Using a realizer that can process logical forms with embedded alternatives provides a substitute for ...
Towards metadata interoperability
Within two European projects metadata interoperability is one of the central topics. While the INTERA project has as one of its goals to achieve an interoperability between two widely used metadata sets for the domain of language resources, the ECHO ...
A web application using RDF/RDFS for metadata navigation
This paper describes using RDF/RDFS/XML to create and navigate a metadata model of relationships among entities in text. The metadata we create is roughly an order of magnitude smaller than the content being modeled, it provides the end-user with ...
The semantics of markup: mapping legacy markup schemas to a common semantics

A method for mapping linguistic descriptions in plain XML into semantically rich RDF/OWL is outlined and demonstrated. Starting with Simons's (2003) original proof of concept of this method, we extend his Semantic Interpretation Language (SIL) for ...
Extensible multimodal annotation markup language (EMMA): invited talk
This talk will introduce the W3C Multimodal Interaction Activity, whose goal is to design a framework of specifications to enable access to the Web using multi-modal interaction. In particular we will introduce the Extensible MultiModal Annotation (EMMA)...
Converting Mikrokosmos frames into description logics
Mikrokosmos contains an ontology plus a number of lexicons in different languages that were originally developed for machine translation. The underlying representation formalism for these resources is an ad-hoc frame-based language which makes it ...
Feeding OWL: extracting and representing the content of pathology reports
This paper reports on an ongoing project that combines NLP with semantic web technologies to support a content-based storage and retrieval of medical pathology reports. We describe the NLP component of the project (a robust parser) and the background ...
An extensible framework for efficient document management using RDF and OWL
In this paper, we describe an integrated approach towards dealing with various semantic and structural issues associated with document management. We provide motivations for using XML, RDF and OWL in building a seamless architecture to serve not only as ...
Towards ontology-based natural language processing
Conceptualising a domain has long been recognised as a prerequisite for understanding that domain and processing information about it. Ontologies are explicit specifications of conceptualisations which are now recognised as important components of ...

RDFS(FA): Connecting RDF(S) and OWL DL
Semantic Web (SW) languages are supposed to be compatible with each other in a meaningful way, so as to facilitate machine understanding. Recent research, however, shows that the semantics of the standard SW annotation language RDF (as well as its ...
Using OWL for querying an XML/RDF syntax
WWW '05: Special interest tracks and posters of the 14th international conference on World Wide WebSome recent initiatives try to take profit from RDF to make XML documents interoperate at the semantic level. Ontologies are used to establish semantic connections among XML languages, and some mechanisms have been defined to query them with natural XML ...
Transforming XML documents to OWL ontologies: A survey
The aims of XML data conversion to ontologies are the indexing, integration and enrichment of existing ontologies with knowledge acquired from these sources. The contribution of this paper consists in providing a classification of the approaches used ...
