学术虚拟社区核心用户兴趣迁移模型构建研究

Research on the Construction of Core User Interest Transfer Model in Academic Virtual Community

[目的/意义]针对目前学术虚拟社区存在对核心用户兴趣变化关注不足的问题,本文基于艾宾浩斯遗忘曲线构建用户兴趣迁移模型,以准确描述核心用户的兴趣迁移,提升对核心用户个性化推荐结果的准确率。[方法/过程]以"小木虫论坛"为研究对象,构建用户影响力评估指标和问答网络,分别利用熵权法和PageRank算法识别核心用户。在此基础上,基于艾宾浩斯遗忘曲线构建核心用户兴趣迁移模型,并对此模型的适用性进行验证。[结果/结论]本文所构建的核心用户兴趣迁移模型能更好地反映核心用户的兴趣迁移。

[Objective/Meaning] Aiming at the current academic virtual community’s insufficient attention to changes in core user interest,this paper builds a user interest transfer model based on the Ebbinghaus forgetting curve to accurately describe the core user’s interest transfer and improve the accuracy of personalized recommendations for core users. [Method/Process] The paper took the "emuch BBS" as the research object,constructed user influence evaluation indicators and question-and-answer network,and then respectively used entropy method and PageRank algorithm to identify core users. On this basis,the core user interest transfer model was constructed based on the Ebbinghaus Forgetting Curve,and the applicability of this model was verified. [Results/Conclusions] The core user interest transfer model constructed in this paper could better reflect the core user’s interest transfer.
