  • 1. Searching with an Integrated Ontology Floor Verdenius, Jan Top, Nicole Ketelaars ATO B.V. P.O. Box 17 6700 AA Wageningen The Netherlands [email_address]
  • 2. Content
    • Introduction
    • Principles
    • Examples
    • Realisation
  • 3. Introduction
    • Goal of the pilot
    • Illustrating the power of an Agricultural Ontology Server in identifying relevant information
    • Objectives
    • Easy to realize pilot
    • Using real world cases
    • Providing actual illustration of the concept
  • 4. Introduction
    • Benefits
    • Illustration of AOS potential
    • Preparation of full AOS proposal
    • Improved search quality in A/OL
    • Search service for Combase domain
    • Technology
    • Ontologies are developed in Protégé
    • The AOS pilot is a prototype web application
    • The AOS pilot calls an external search engine
  • 5. Introduction
    • Results
    • Dedicated domain ontology for Combase,
    • Common A/OL-Combase ontology consisting of the shared concepts
    • Demonstration of improved search capacity for at least 3 queries; for each query:
      • search without an ontology
      • search with A/OL ontology
      • search with integrated AOS ontology (A/OL & Combase)
      • search both deep and wide in the ontologies
  • 6. Principles
    • Domain ontologies:
      • A/OL: Structured knowledge on Anti-microbial Compounds
      • Combase: Structured knowledge on Microbial Growth
    • A/OL ontology
    • Anti-microbial compounds
    • Food substrates
    • Experiments
    • Measurements
    • Micro-organisms (list)
    • Combase ontology
    • Microbial growth
    • Biochemistry
    • Micro-organisms (taxonomy)
    Cross-domain ontology Reconciled & unified concepts (e.g. micro-organisms)
  • 7. Searching using an ontology
    • Searching is more efficient, because concepts have a meaning and a relation with respect to other concepts.
    • Example: beer
      • lager, stout and ale are types of beer (child of)
      • beer is an alcoholic beverage, like wine (type of)
    deep search wide search

  • 14. Realization
    • A/OL Ontology
      • Formulating the ontology for Anti-microbial compounds
      • (part of the A/OL project)
    • Combase ontology
      • Formulating the ontology for Microbial Growth
      • Formalizing knowledge that fills the Combase simulation system
    • Mapping A/OL & Combase ontology
      • Identification of shared concepts in ontologies
      • Reformulating ontologies based on cross domain ontology
    • Search demonstration
      • Demonstration of search performances on 3 representative search queries
