In this paper, we described the evolution of the AGROVOC thesaurus to AGROVOC Concept Scheme based on OWL (web ontology language) model and now shifting to SKOS (simple knowledge organization system) model. The paper explained why and how it evolved highlighting the key differences between different models. The system architecture and significant set of features available in the VocBench was discussed in the paper.展开更多

Derived by the application requirement, the paper also puts forward to a bilingual retrieval model on the basis of CAT/AGROVOC mapping, designs and realizes the ZH/EN bilingual retrieval prototype system.展开更多

文摘For the users' convenience of accessing the AGRIS resources quickly and using them fully, the paper decomposes the structure of AGRIS Search net, analyzes the users' requirement met for conducting a bilingual (ZH/EN) retrieval, the system function extensions based on AGRIS English retrieval system and the key issues which the core function module should resolve. Derived by the application requirement, the paper also puts forward to a bilingual retrieval model on the basis of CAT/AGROVOC mapping, designs and realizes the ZH/EN bilingual retrieval prototype system.
