摘要: [目的/意义]以三元交互决定论为基石构建在线学术社区动态知识推荐服务模型,为在线社区多维需求分析及需求演变趋势刻画提供理论依据,为完善知识社区的推荐服务提供相应指导。[方法/过程]首先,基于三元交互决定论明确影响用户知识需求的内外因素以及因素间的关联关系;然后根据三元交互决定论需求分析的目标,明确相应的分析方法,抽取出用户各维度的知识需求特征;最后对各维度的需求特征进行整合并构建知识需求链以刻画三要素交互作用下的用户需求演变轨迹,利用需求链的相似度计算预测用户的将来知识需求,对用户的知识需求分析进行扩充;[结果/结论]基于三元交互决定论的知识推荐服务体系,从全局视角充分考虑了用户需求的各项影响因素,提高了社区对用户需求刻画的细粒度,对学术社区知识服务水平的提高具有重要的参考价值。

Abstract: [Purpose/Significance] This paper constructs a dynamic knowledge recommendation service model oriented to online academic communities based on ternary interactive determinism to provide a theoretical basis for online community multi-dimensional demand analysis and demand evolution trend description, to improve the knowledge community recommendation services. [Method/Process] Firstly, based on the ternary interactive determinism, we clarify the internal and external factors that affect the user's knowledge needs and analyze the relationship between the factors. Secondly, according to the needs analysis objective of the ternary interactive determinism, we clarify the corresponding analysis methods and extract the characteristics of users' knowledge needs in various dimensions. Finally, we integrate the demand characteristics of various dimensions and build a knowledge demand chain to describe the evolution of user demand under the interaction of the three elements. We use the similarity of the demand chain to calculate and predict the future knowledge demand of users to expand the analysis of users' knowledge demand. [Results/Conclusions] The knowledge recommendation service system based on the ternary interactive determinism fully considers the various influencing factors of user needs from a global perspective, improves the fine-grained characterization of user needs in the community, and provides reference for academic communities to improve their knowledge service levels.

Key words: online academic community, ternary interactive determinism, dynamic knowledge recommendation service, knowledge service
