Automatically Extracting Ontologically Specified Data from HTML Tables with Unknown Structure

by David W. Embley, Cui Tao, Stephen W. Liddle - In Proceedings of the 21st International Conference on Conceptual Modeling (ER’02 , 2002
"... Data on the Web in HTML tables is mostly structured, but we usually do not know the structure in advance. Thus, we cannot directly query for data of interest. We propose a solution to this problem based on document-independent extraction ontologies. The solution entails elements of table understandi ..."

BayesOWL: Uncertainty modeling in Semantic Web ontologies

by Zhongli Ding, Yun Peng, Rong Pan, Zhongli Ding, Yun Peng, Rong Pan - Soft Computing in Ontologies and Semantic Web, volume 204 of Studies in Fuzziness and Soft Computing , 2005
"... It is always essential but difficult to capture incomplete, partial or uncertain knowledge when using ontologies to conceptualize an application domain or to achieve semantic interoperability among heterogeneous systems. This chapter presents an on-going research on developing a framework which augm ..."

augments and supplements the semantic web ontology language OWL 5 for representing and reasoning with uncertainty based on Bayesian networks (BN) [26], and its application in ontology mapping. This framework, named BayesOWL, has gone through several iterations since its conception in 2003 [8, 9]. Bayes

Evolving and Validating Annotations in Web-based Collaborative Environments through Ontology Matching∗

by Angela Locoro, Viviana Mascardi, Anna Marina Scapolla
"... The research presented in this paper describes an automated approach for extracting concepts from annotated shared con-tents within a collaborative web environment, and matching them with domain ontologies. Feedback on the domain on-tology suitability for the environment purposes is provided as a re ..."

DAML-QoS Ontology for Web Services

by Chen Zhou, Liang-tien Chia, Bu-sung Lee - In Proceedings of the IEEE Int. Conf. on Web Services (ICWS 2004 , 2004
"... As more and more Web services are deployed, Web service’s discovery mechanisms become essential. Similar services can have quite different QoS levels. For service selection and management purpose, it is necessary to explicitly, precisely, and unambiguously specify various constraints and QoS metrics ..."

constraints. Basic profile is presented for general web service’s description and the speed startup of ontology definition. Matchmaking algorithm for QoS property constraints is presented and different matching degrees are described. When incorporated with DAML-S, multiple service levels can be described

Ontology support for web services processes

by C. Pahl - Proc. of ESEC/FSE ’03 , 2003
"... Web Services are software services that can be advertised by providers and deployed by customers using Web technolo-gies. This concept is currently carried further to address Web service choreography. Choreography refers to the com-position of individual services to services processes that can commu ..."

We propose a formal ontology framework for these Web service processes that supports the description, matching, and composition through logic reasoning techniques. The Semantic Web, based on a description logic-based knowl-edge representation and reasoning framework

Ontology Generation from Tables 1

by Yuri A. Tijerino, David W. Embley, Deryle W. Lonsdale, George Nagy

Ontology Matching with Axioms and Conceptual Graphs

by Frédéric Fürst, Francky Trichet
"... Strategies for matching ontologies are diverse, but most of them consider only alignment between lightweight ontologies—that is, ontologies composed of concept and relation taxonomies. Heavyweight ontologies additionally include axioms to represent a domain’s full semantics. 1 Not many realworld ont ..."
