Transcript

  • 1. Towards anecosystem of data and ontologies Mathieu d’Aquin and Enrico Motta Knowledge Media Institute The Open University
  • 2. Large scale semantics on the web • Traditional research and use of ontologies has been piecemeal: 1. develop ontology 2. annotate data with ontology • With the explosion of ontologies and data on the web, the landscape has changed – Thousands of ontologies are now available online, while huge quantities of data are generated all the time. • This unprecedented scenario introduces new opportunities for both fundamental and applied research
  • 3. Experience from using online ontologies NeOn Project Methodological and technological support for networked ontologies – Ontology modularization, ontology design patterns, ontology alignments, ontology reuse, ontology search, ontology visualisation, ontology evolution… Key Infrastructure Component Watson: ontology search engine and API for exploiting available online ontologies. Used in: – knowledge-based ontology matching – query answering, word sense disambiguation – information retrieval, semantic enrichment of folksonomies, semantics-enhanced Web browsing, ...RefercencesdAquin, Motta et al.

  • 4. New challenges/research directions – Automatically aligning data and ontologies to make sense of both data and ontologies. For example: • Enabling automatic evolution of ontologies • Tidying up and automatically augment linked data sources – Mapping the landscape of semantics on the web. For example: • Automatically identifying relations between ontologies • Identifying and comparing different conceptual viewpoints on the same domain – Cf. our work on measuring agreement and disagreement – Understanding usability of ontologies through appropriate emprical studies References dAquin, M.

  • 5. Steps forward Need for Web-scale supporting infrastructures for online ontologies – Ontology repositories exist, but small coverage, scope, etc. – Need support for sustainable and accountable publishing of ontologies – Supporting usage monitoring and appropriate re- use, including “find by example” / “find alternatives” Need for empirical investigations of online ontologies – Understanding the practices in knowledge representation, ontology design and ontology engineering through analyzing the large amounts of interconnected ontologies online – Understanding the practices in using ontologies and how data and ontologies interact on the WebReferencesAllocca, dAquin and Motta (2009) DOOR: Towards a Formalization of Ontology Relations, KEOD 2009dAquin, Allocca, and Motta (2010) A Platform for Semantic Web Studies, Web Science 2010dAquin and Noy (2011) Where to publish and find ontologies?
