    • Adding Integrity Constraints to the Semantic Web for Instance Data Evaluation 

      Tao, Jiao (2010-11-07)
      This paper presents our work on supporting evaluation of integrity constraint issues in semantic web instance data. We propose an alternative semantics for the ontology language, i.e., OWL, a decision procedure for constraint ...

    • An Initial Investigation on Evaluating Semantic Web Instance Data 

      Ding, Li; Tao, Jiao; McGuinness, Deborah L. (2008-04-21)
      Many emerging semantic web applications include ontologies from one set of authors and instance data fromanother (oftenmuch larger) set of authors. Often ontologies are reused and instance data is integrated in manners ...

    • Characterizing and Detecting Integrity Issues in OWL Instance Data 

      Tao, Jiao; Ding, Li; Bao, Jie; McGuinness, Deborah L. (2008-10-26)
      We view OWL instance data evaluation as a process in which instance data is checked for conformance with application requirements. We previously identified some integrity issues raised by applications demanding closed world ...

    • Characterizing Services Composeability and OWL-S based Services Composition 

      Yang, Zhonghua; Zhang, Jing-Bing; Tao, Jiao; Gay, Robert (2005-11-30)
      Grid has emerged as a new paradigm for integration within dynamic virtual enterprises. Given a service-oriented Grid environment, more complex, value-added sophisticated services and applications can be built via service ...

    • Context Representation for the Semantic Web 

      Bao, Jie; Tao, Jiao; McGuinness, Deborah L.; Smart, Paul (2010-01-01)
      The unambiguous and effective delivery of data and knowledge on the Web relies heavily on the correct representation and understanding of the associated contexts. However, the current way of encoding data and knowledge on ...

    • Extending OWL with Integrity Constraints 

      Tao, Jiao; Sirin, Evren; Bao, Jie; McGuinness, Deborah L. (2010-05-04)

    • Instance Data Evaluation for Semantic Web-Based Knowledge Management Systems 

      Tao, Jiao; Ding, Li; Bao, Jie; McGuinness, Deborah L. (2009-01-05)
      As semantic web technologies are increasingly used to empower knowledge management systems (KMSs), there is a growing need for mechanisms and automated tools for checking content generated by semantic-web tools. The content ...

    • Integrity Constraints for the Semantic Web: An OWL 2 Description Logic Extension 

      Tao, Jiao (2012-03-19)
      With the extensive applications of Semantic Web technologies, an increasing amount of data has been published and consumed on the Semantic Web. Given some instance data, one might wonder if the data is ready for use. To ...

    • Integrity Constraints in OWL 

      Tao, Jiao; Tao, Jiao; Sirin, Evren; Sirin, Evren (2010-06-07)
      In many data-centric applications, it is desirable to use OWL as an expressive schema language with which one expresses constraints that must be satisfied by instance data. However, specific aspects of OWL's standard ...

    • OWL Instance Data Evaluation 

      Ding, Li; Tao, Jiao; McGuinness, Deborah L. (2008-04-01)
      As more applications are depending on semantic web data from diverse sources, semantic web data evaluation is becoming more critical. While language validators and general reasoners can help, these typically focus on syntax ...

    • Towards Integrity Constraints in OWL 

      Sirin, Evren; Tao, Jiao (2009-10-23)
      In many data-centric applications, it is desirable to use OWL as an expressive schema language with which one expresses constraints that must be satisfied by instance data. However, specific aspects of OWL's standard ...
