The conceptual knowledge network based on keyword co-occurrence is a complex network with hierarchical structure, which can be divided into different layers in term of the k-core value of nodes. This paper introduces the theory of triadic closure as the basic unit of network structure analysis.From the hierarchical perspective, different type of triadic closures can represent different structure of knowledge connections, such as the cluster of similar nodes, knowledge fusion and knowledge differentiation.In the case of digital libraries, conceptual knowledge network with keywords can be divided into three layers.Based on the distinctions of nodes and triadic closures, it can make a deeper analysis on the microscopic connection structure among nodes in the knowledge network.
