As part of the publication of the AGROVOC thesaurus as Linked Data (LD), AGROVOC is now mapped with six well-known thesauri in the agricultural domain, i.e., EUROVOC, NALT, GEMET, STW, TheSoz, RAMAEU. To find matching candidates, known matching algorithms discussed in the literature and available from public API were used. Results were evaluated by a domain expert, and almost total precision ob...

The AGROVOC multilingual thesaurus maintained by the Food and Agriculture Organization of the United Nations (FAO) is now published as linked data. In order to reach this goal AGROVOC was expressed in Simple Knowledge Organization System (SKOS), and its concepts provided with dereferenceable URIs. AGROVOC is now aligned with ten other multilingual knowledge organization systems related to agric...

This paper describes the procedures for a concept-based mapping of two agricultural thesauri, the multilingual AGROVOC, created and maintained by the Food and Agricultural Organization, and the bilingual Chinese Agricultural Thesaurus, created and maintained by the Chinese Academy of Agricultural Science. Conducted under the auspices of FAO’s Agricultural Ontology Service, the mapping project a...

In the Food and Agriculture Organization of the United Nations (FAO), the need to revamp its popular agriculture vocabulary AGROVOC using Semantic Web knowledge representation standards combined with the need to provide a collaborative environment for development and maintenance purposes, pushed forward the realization of a dedicated AGROVOC thesaurus maintenance tool. With the progressive stan...

Born in the early 1980’s as a multilingual agricultural thesaurus, AGROVOC has steadily evolved over the last fifteen years, moving to an electronic version around the year 2000, and embracing the Semantic Web shortly thereafter. Today AGROVOC is a SKOS-XL concept scheme published as Linked Open Data, containing links (as well as backlinks) and references to many other Linked Datasets in the LO...

Newly acquired, aggregated and shared data are essential for innovation in food agriculture to improve the discoverability of research. Since early 1980′s, Food Agriculture Organization United Nations (FAO) has coordinated AGROVOC, a valuable tool be classified homogeneously, facilitating interoperability reuse. AGROVOC is multilingual controlled vocabulary designed cover concepts terminology u...

The Food and Agriculture Organization is developing a concept based multilingual vocabulary management tool to manage thesauri, authority lists and glossaries expressed as concept schemes ready to be used in a linked data environment. 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 (...

Relation extraction is an important step in Ontology construction. This paper provides a method to extract relations among conceptions with AGROVOC.

This paper describes a multilingual semantic search assistant (MSSA) that could help users find proper keywords in FAO fulltext-based search engines. The MSSA implements four independent functions each associated with the AGROVOC multilingual thesaurus to assist users in choosing better keywords: a Venn diagram-based Boolean search interface, an animated AGROVOC concept browser, cross-language ...
