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

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

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

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)

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

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
