    A Comprehensive Framework for Building Multilingual Domain Ontologies: Creating a Prototype Biosecurity Ontology 2002
    Also available in:
    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.

    This document describes and discusses the fisheries ontologies developed for use within the Fish Stock Depletion Assessment System (FSDAS). All ontologies are publicly available from the FAO website, from http://www.fao.org/aims/aos/fi. This document is organized as follows. In Chapter 1 we place our work in the context of the WP7 case study. In Chapter 2 we describe previous attempts to create ontologies for the fisheries domain. In Chapter 3 we recap the user requirements presented i n our previous deliverable D7.1.1, with special attention to the functionalities needed for modelling, population and maintenance. In Chapter 4 we describe the domains and the data on which the ontologies described here are based. In Chapter 5 we describe the fisheries database where the data used to populate the fisheries ontologies is stored; we also introduce the tool used for population of the ontologies. In Chapter 6 we describe the models of all ontologies produced. In Chapter 7 we discuss some features of the ontologies. In Chapter 8 we summarize the lessons learned in the course of this work. Finally, in Chapter 9 we draw our conclusions. This document also includes four Annexes: the list of naming conventions adopted (Annex I), an essential glossary of fisheries terms (Annex II) a list of acronyms (Annex III) and a report on the conversion of the XML schema for fisheries factsheets into an ontology.

    D7.4.1 Software architecture for managing the Fisheries ontologies lifecycle

    This document describes the software architecture for implementing a system for managing the fisheries ontologies lifecycle, cornerstone of WP7. The lifecycle described in this deliverable is an instantiation of the possible lifecycles that can be carried out with the NeOn toolkit, and has been selected according to FAO needs, style of work and organizational culture. This document is also an extension and refinement of D7.1.1 in terms of requirements that should be fulfilled by the ge neral NeOn lifecycle management support. The architecture is based on the NeOn Toolkit and engineering components, and will be incrementally integrated into the system through subsequent T7.4 deliverables, i.e. deliverables D7.4.2 and D7.4.3. Since D7.1.1 the requirements about the Fisheries Ontologies Lifecycle have evolved been more concrete (as in any software development process). Chapter 1 of the document describes the major requirements of the Fisheries Ontologies Lifecycle Manag ement System. Chapter 2 provides an overview of the process required for building, populating, publishing and maintaining the fisheries ontologies. Chapter 3 includes use case diagrams and a brief description of each use case required for implementing the system. These use cases are based on the requirements described in early WP7 deliverable D7.1.1, and each use case provides references to the relevant sections in D7.1.1. A detailed description of each use case and the engineering c omponents to be integrated in the system are included in Annex I of this document. Chapter 4 presents the system architecture derived from the use cases, as a selection of components of the NeOn Toolkit and system architecture. Chapter 5 describes the plan for subsequent T7.4 deliverables. Finally, Chapter 6 highlights the major conclusions of deliverable D7.4.1.
