Task to be accomplished

The AGROVOC Thesaurus is currently structured as a traditional thesaurus and is stored in a relational database. It is the foundation for a new structure, more semantically organized, that FAO is planning to release, called the Concept Server, CS. Within the framework of the conversion to a concept server, all these traditional thesaurus relationships need to be refined. This revision primarily includes:

1) Revision and refinement of all BT/NT relationships and identification of real hierarchical relationships which can be represented as ‘suclass of” / “is_a” or as “is an instance of”. (28,625 BTs and 28,617 NTs)
2) Revision and refinement of all RT relationships. (28,219 RTs)
3) Revision of scientific terms and corresponding common names.
4) Revision of all terms which do not have broader terms and identify those that can to be assigned to one or more broader terms.
5) Revision and refinement of USE/UF/UF+ relationships. (19,158 Use, 17,386 UF and 1,775 UF+)
