    From AGROVOC to the Agricultural Ontology Service / Concept Server
    An OWL model for creating ontologies in the agricultural domain
    2006
    Also available in:

    This paper illustrates the conversion from a traditional thesaurus in agriculture (AGROVOC) to a new system, the Agricultural Ontology Service Concept Server (AOS/CS). The Concept Server will serve as a multilingual repository of concepts in the agricultural domain providing ontological relationships and a rich, semantically sound terminology. The Food and Agriculture Organization recently developed the underlying model for this new system in the Web ontology language OWL. In this paper, we desc ribe the purpose of this conversion and the use of OWL and highlight in particular the core features of the developed OWL model. We go on to explain how it evolves and differs from the traditional thesaurus approach.

    A Comprehensive Framework for Building Multilingual Domain Ontologies: Creating a Prototype Biosecurity Ontology 2002

    No results found.

    This paper presents our ongoing work in establishing a multilingual domain ontology for a biosecurity portal. As a prototypical approach, this project is embedded into the bigger context of the Agricultural Ontology Service (AOS) project of the Food and Agriculture Organization (FAO) of the UN. The AOS will act as a reference tool for ontology creation assistance and herewith enable the transfer of the agricultural domain towards the Semantic Web. The paper focuses on introducing a comprehensive, reusable framework for the process of semi-automatically supported ontology evolvement, which aims to be used in follow-up projects and can eventually be applied to any other domain. Within the multinational context of the FAO, multilingual aspects play a crucial role and therefore an extendable layered ontology modelling approach will be described within the framework. The paper will present the project milestones achieved so far: the creation of a core ont ology, the semiautomatic extension of this ontology using a heuristic toolset, and the representation of the resulting ontology in a multilingual web portal. The reader will be provided with a practical example for the creation of a specific domain ontology, which can be applied to any possible domain. Future projects, including automatic text classification, and ontology facilitated search opportunities, will be addressed at the end of the paper.

    A core ontology of fishery and its use in the fishery ontology service project 2004
    Also available in:
    No results found.

    Ontology creation and document indexing are well-known, critical bottlenecks for integrating semantic services and in general for bootstrapping the Semantic Web. For certain domains or communities, legacy terminologies and indexing methods exist which can be reused effectively. In the Fishery Ontology Project (FOS), we have reengineered and aligned legacy thesauri by using formal ontological methods, and we are deploying the resulting ontology library (currently including more than 3 5,000 classes and about 10,000 individuals) for services dedicated to fishery document repositories and databases. Alignment, reengineering, and modularization of the library leverage on the Core Ontology for Fishery developed in FOS. Its structure and use are described in this paper.
