Abstract

Abstract:

In the face of increasingly abundant knowledge resources, low-cost, high-precision knowledge transfer mechanisms can support knowledge service organizations to provide good knowledge services for knowledge users, realize effective allocation of knowledge resources, and improve the utilization of knowledge resources. This paper takes tacit knowledge as the research object, and proposes a model of tacit knowledge transfer based on three-way decision aiming at the characteristics of knowledge itself. The model mainly includes three parts: matching the user’s knowledge needs with existing knowledge resources; determining the decision threshold $\left( \alpha,\beta \right)$ based on the transfer cost; determining the region of “transfer” “non-transfer” and “delayed transfer” based on decision threshold. The empirical results show that, compared with the existing methods, the implicit knowledge transfer model based on three-way decision proposed in this paper reduces the cost of knowledge transfer due to misclassification by subdividing the transfer area. Meanwhile, the decision area is determined according to the similarity of views, improving the accuracy of knowledge transfer.

Key words: knowledge service, tacit knowledge, knowledge transfer, three-way decision

摘要：

面对日益丰富的知识资源,低成本、高精度的知识转移机理能够支撑知识服务型组织为知识用户提供良好知识服务、实现知识资源有效配置及提高知识资源利用率。以隐性知识为研究对象,针对知识本身的特性,提出基于三支决策的隐性知识转移模型。该模型主要包含三部分：用户知识需求与既有知识资源的匹配;根据转移成本确定决策阈值$\left( \alpha,\beta \right)$;根据决策阈值确定隐性知识转移的划分区域“转移”“不转移”和“延迟转移”。实证结果表明,与既有方法相比,提出的基于三支决策的隐性知识转移模型通过对转移区域的细分,降低了因错误分类而产生的知识转移成本;同时,根据视图相似度确定决策区域,提高了知识转移的准确性。
