The notion of visibility of knowledge is important to gain insights into an evolving knowledge-sharing practice through social media use. This article offers a conceptual definition of and an instrument to measure the visibility of knowledge in online communities facilitated by social media. Following a review of the relevant literature and interviews with experts and knowledge workers, we produced a preliminary conceptual definition of visibility of knowledge in social media. Then, using four different datasets, we assessed the content validity of the items representing visibility of knowledge (n=218), pre-tested the scale (n=235), assessed the scale validity (n=333), cross-validated the scale (n=228), and established its nomological validity. This study contributes to the literature by providing a comprehensive conceptualization of an instrument for visibility of knowledge that can be used to understand the evolving knowledge-sharing process and its consequences on individual and organizational outcomes.

知识可见性的概念对于通过社交媒体的使用深入了解不断发展的知识共享实践非常重要。本文提供了一个概念定义和衡量社交媒体促进的在线社区中知识可见度的工具。在回顾了相关文献并采访了专家和知识工作者之后，我们对社交媒体中知识的可见性做出了初步的概念定义。然后，使用四个不同的数据集，我们评估了代表知识可见性的项目的内容效度（n=218），预测试量表（n=235），评估量表效度（n=333），交叉验证量表（n = 228），并确定了它的法理效度。
