摘要
This paper studied the construction of Pomology Domain Ontology (PDO), and the realization of PDO-based query system. First, an approach to build PDO based on Agriculture Science Thesaurus (AST) was proposed, which consists of confirming core concepts, adding the properties of concepts, confirming the relationships between concepts, adding the instances of concepts, and representing domain ontology. Then the PDO-based query system model and implementation algorithm were given. The query system realized class query, instance query, and property query by Jena. Query results indicate that the algorithm is practical and the search time is shortened. Through the query system pomology knowledge can be obtained from PDO according to user needs.
