Abstract This paper represents the descriptor, non-descriptor and semantic relationships of Chinese Agricultural Thesaurus (CAT) as SKOS, and develops an application to convert CAT to CAT/SKOS automatically, and indexes millions of agricultural abstracts semantically based on CAT/SKOS, Solr and the improved Lucene-SKOS plugin. Then it realizes a semantic retrieval prototype system, which supports cross-language search (Chinese and English), and can also extend and reconstruct the query based on semantic relationship in CAT/SKOS. Finally, the authors make some prospects on the future applications of CAT/SKOS such as the publication as Linked Data.
