Abstract Web 2.0 application technologies, such as blog, instant messaging, social network, community sharing, and Folksonomy, enable the combination of users, information, and resources to form a closely related web network. In recent times, there have been limited research studies that apply ontology to analyze the dynamic interests of the users of social tags. Therefore, a platform’s requirements related to an accurate understanding of its users’ interests are not fulfilled. Our study discusses the construction method of interest model from this standpoint. The ontology of interest labels for Douban readers is constructed in this study on the basis of restriction rules and relationship definitions of words in the Chinese Classification Thesaurus and Chinese Library Classification. According to the index of reproduction, coverage, and calorific rate, the interest intensity and stability of tags are predicted, and the expression form of interest is determined. The initial interest model is then constructed, and the corresponding renewal process of interest nodes is proposed. The user’s interest model combined with ontology and its update process have improved the expression depth and width of user interests to a certain extent. Thus, this work demonstrates a higher scientific reference significance in the applicability of resource recommendation, retrieval, and other applications.
