    Applying New Trends to the Management of Bibliographic Information on Agriculture 2004

    With the current rapid developments in the field of information management, it has become important to keep abreast with the new technologies and to apply them appropriately, wherever possible, to improve access to information. This paper gives an outline of the current initiative at FAO that attempts to implement these new technologies with the primary aim of providing improved access to agricultural information. This initiative, which comprises the Agricultural Metadata Element Set (AgMES) and Agricultural Ontology Service (AOS) projects, seeks to provide standards to describe resources in the agricultural domain, by using well-known metadata sets and domain-specific controlled vocabularies, such as thesauri, classification schemes, and ontologies.[1,2] The paper gives a basic overview on the concept of metadata and its importance in facilitating information discovery, and on the use of XML as a platform-independent tool for achieving interoperability between different applications i n the domain of agriculture. The second half of the paper introduces ontologies and describes their usefulness in representing and reusing domain knowledge for providing precise concept-based search results.

    Metadata application profile for agricultural learning resources 2007
    Also available in:
    No results found.

    Capacity and institution building is a core function of the Food and Agricultural Organization of the United Nations (FAO). FAO has recently started the “Capacity and Institution Building Portal” to provide structured access to information on FAO’s capacity and institution building services and learning resources. To ensure that the Portal can be searched by users and to enable interoperability with other recognized educational repositories, an Application Profile (AP) was created co nforming to available and commonly used standards, to describe agricultural learning resources. This article presents the AP, provides an example of an FAO learning resource described and displayed using FAO Learning Resource AP, and presents the lessons learned.

    Ontology-based navigation of bibliographic metadata: example of the Food, Nutrition and Agriculture Journal 2007
    Also available in:
    No results found.

    This paper describes the work done within the Food and Agriculture Organization of the United Nations (FAO) on providing an ontology-based navigation to the Food, Nutrition and Agriculture (FNA) Journal. The aim of the revised navigation was to provide more efficient and effective browsing of the Food and Nutrition Publications using a knowledge model to guide the user with concepts and relationships relevant to a specific subject area. With this approach, data from two different bibliographica l databases were reused, by merging and unifying them and make them better accessible to users. A preliminary metadata merge was needed to combine all the information into one system in order to produce a metadata-ontology. Resource Description Framework Schema (RDFS) has been chosen to exploit semantic relationships e.g. the possibilities of browsing the data in different ways (by keywords, categories, authors, etc.), and the creation of a multilingual concept-based advanced search.
