对知识网络形成与演化的周期性和规律性进行研究,提出知识网络生命周期模型.提取知识网络形成与演化过程的阶段特征因素,运用基于模糊贴近度的多目标分类算法进行了生命周期阶段判定,旨在为实施知识网络管理、实现知识网络的可持续发展提供支持和指导.%This paper studies the life cycle of knowledge networks, and constructs a life cycle model. Based on the extraction of the key characters of each phase in its life cycle, a judgment model of the life cycle for knowledge networks based on fuzzy similarity scale is developed. The results have an important role in the support and guidance for the implementation of the knowledge network management and realization of knowledge networks' sustainable development.
