Transcript

  • 1. Introduction
    • Meta-Data Model for Ontology Mapping Management
  • 2. 1. Character Phase (1/2)
    • Target and the source ontology are identified:
    • Ontology Name: a label for the ontology Ontology on Animals
    • Ontology Source: Where can I find the ontology file? www.wikipedia.org/animal.owl
    • Ontology PSI: Unique identifier
    • www.ontologies.org/animal
    • Ontology creation date: 2010-05-04
    • Ontology author: name:Hendrik, email: [email_address]
  • 3. 1. Character Phase (2/2)
    • Target and the source ontology are characterizes:
    • Ontology language: Format of the ontology OWL DL, RDF
    • Ontology size: How big is the ontology 5 classes, 10 individuals
    • Ontology style: What does the ontology look like deep hierarchy , flat hierarchy, network
  • 4. 2. Matching Phase (1/2)
    • Describes the method used to identify the candidates:
    • Method: How were the candidates found? manual selection or automated algorithm
    • Date of selection: When was selection performed 2010-05-06
    • Describes the manual selection :
    • Selectors: Who did the selections? Hendrik, Andre, Declan (contact details)
    • Selectors background: relevant details about selectors Selectors had experience in Semantic Web
    • Selection process: details about the selection process Selectors analyzed all ontology elements Selectors group equal elements based on name similarity
  • 5. 2. Matching Phase(2/2)
    • Describes the automated matching:
    • Algorithm name: human-readable label String comparison
    • Algorithm implementation: org.jena.stringComparsion
    • Selection process: details of selection process Matching based on string similarity
  • 6. 3. Mapping Phase (2/2)
    • Describes the mapping context:
    • Mapping objective: What is the purpose/aim of the mappings? Enable knowledge exchange between ontologies
    • Mapping requirements: What rules have to be followed? Do not map product ids
    • Mapping context: What is the context? Mapping is created for Wikipedia.de
    • Mapping is used for a demonstrator
    • Describes the mapping process :
    • Mapping process: details about the mapping process Confirm mapping with similarity rating of > 0.5 %
    • Date of mapping: When was selection performed 2010-05-06
  • 7. 4. Execution Phase
    • Describes the application of the mapping:
    • Mapping format: INRIA RDF
    • Mapping users: Known users of the mappings Hendrik Thomas
    • Application using mapping: Known application which used the mappings Wikipedia.de/mapMe
  • 8. 5. Management Phase
    • Describes the sharing of the mapping:
    • Source of the mapping file: www.mapme.org/m.rdf
    • Hashkey: unique key of mappings 23434534646456456
    • LastChange: 2010-06-03
