    Towards an architecture for open archive networks in Agricultural Sciences and Technology 2007
    The AGRIS Network is an international initiative based on a collaborative network of institutions, whose aim is to promote free access to information on science and technology in agriculture and related subjects. The paper illustrates how the Open Access (OA) and the Open Archive Initiative (OAI) models can be used within the AGRIS Network as a means of solving the problems of dissemination and exchange of agricultural research outputs. The lack of adequate information exchange possibilities bet ween researchers in agricultural sciences and technology represents a significant weakness limiting their ability to properly address the issues of agricultural development. The OA model promotes the dissemination of research output at international, national and regional levels thus removing the restrictions placed by the traditional scientific publishing model. This paper presents the possibility to address the accessibility, availability and interoperability issues of exchanging agricultural research output.

    The new AGRIS initiative, which was launched at the Expert Consultation in October 2005, has defined three main areas of intervention to improve international information systems in agricultural science and technology: Advocacy, Capacity Building and Content Management. Content management, the management of agricultural science and technology information, has various needs: standards and methodologies for interoperability and facilitation of knowledge exchange; tools to enable information mana gement specialists to process data; information and knowledge. This paper describes some of the efforts which have been made in this area over recent years.

    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.
