Besides, two kinds of models in NKRM system have been introduced. And one of the most common methods to improve reliability is the redundant technique. However, reliability and efficiency are inconsistent each other. By treating each knowledge as one part of the system, this paper proposes method of joint reserve of knowledge that may resolve this problem.展开更多

In this paper, botany-specific ontology for acquiring and analyzing botanicalknowledge is presented. The ontology is represented in a set of well-defined categories, and eachconcept is viewed as an instance of certain category. The authors also introduce botany-specificaxioms, an integral part of the ontology, for checking and reasoning with the acquired knowledge.Consistency, completeness and redundancy of the axioms are discussed.展开更多
