Multi perspective Ontology Engineering

Published on

Description of my PhD for an invited talk at the Department of Computer Science at Sheffield University. I present my hypothesis that different ontology authors have different views on the world, and different requirements of ontologies which results in different definitions of 'the same' concepts.

I propose to make ontology tools that are bias-aware to help in the creation and reuse of ontologies. In this context I present my current work on making a goal-aware ontology editor.

  17. 17. Background and Motivation Multi-perspective Ontology Engineering Contributions Ontology Purposes Ontology Development 101 Natalya F. Noy and Deborah L. McGuinness There is no one correct way to model a domain there are always viable alternatives. The best solution almost always depends on the application that you have in mind and the extensions that you anticipate. . . . deciding what we are going to use the ontology for . . . will guide many of the modeling decisions down the road.1 1 N. F. Noy and D. Mcguinness. Ontology development 101: A guide to creating your first ontology, 2000 Denaux, Cohn, Dimitrova and Hart Multi-Perspective Ontology Engineering
  18. 18. Background and Motivation Multi-perspective Ontology Engineering Contributions Ontology Purposes METHONTOLOGY The goal of the specification phase is to produce either an informal, semi-formal or formal ontology specification document. METHONTOLOGY proposes that at least the following information be included: (a) The purpose of the ontology, including its intended uses, scenarios of use, end-users, etc. ... 2 2 M. Fernandez-Lopez, A. Gomez-Perez, and N. Juristo. Methontology: from ontological art towards ontological engineering.

  19. 19. Background and Motivation Multi-perspective Ontology Engineering Contributions Ontology Purposes DILIGENT Local adaptation: once the core ontology is available, users work with it and adapt it locally to their own needs. Typically, they will have their own business requirements and correspondingly change their local ontologies. 3 3 Denny Vrandecic, H. Sofia Pinto, York Sure, and Christoph Tempich.
