Book (stand-alone)The Mapping Schema from Chinese Agricultural Thesaurus to AGROVOC 2005
Also available in:
No results found.This paper introduces the criteria and the procedures for mapping the Chinese Agricultural Thesaurus (CAT) to FAO’s multilingual agricultural thesaurus AGROVOC. It proposes modifications to the interthesaurus mapping rules provided in the Simple Knowledge Organization System (SKOS) specification. It outlines in detail the criteria for the application of each of the mapping rules. We will describe the procedure for the application for these rules and give concrete examples taken from both thesaur i. -
Book (stand-alone)Reengineering Thesauri for New Applications: the AGROVOC Example 2004
Also available in:
No results found.Existing classification schemes and thesauri are lacking in well-defined semantics and structural consistency. Empowering end users in searching collections of ever increasing magnitudes with performance far exceeding plain free-text searching (as used in many Web search engines), and developing systems that not only find but also process information for action, requires far more powerful and complex knowledge organization systems (KOSs). The paper presents a conceptual structure and transition procedure to support the shift from a traditional KOS towards a full-fledged and semantically rich KOS. The proposed structure also complies with other interoperability approaches like RDFS and XML in the Web environment. AGROVOC, a traditional thesaurus developed and maintained by the Food and Agriculture Organization (FAO) of the United Nations, serves as a case study for exploring the reengineering of a traditional thesaurus into a fully-fledged ontology. We start the process of developing an inventory of specific relationship types with well-defined semantics for the agricultural domain and explore the rules-as-you-go approach to streamlining the reengineering process. -
Book (stand-alone)Information technologies and standards for agricultural information resources management: AGRIS Application Profile, AGROVOC and LISAGR 2007
Also available in:
No results found.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.
