摘　　要：随着连通技术与联通主义理论的支持与深入,在线学习中学习者兼具知识消费者与知识生产者双重角色,知识创造被视为重要的学习活动。知识创造理论与模型的研究逐步涌现,但是仍缺乏量化方法对知识创造过程与规律的有效揭示。为此,研究基于知识创造隐喻理论,以主题“人造物”视角,引入主题抽取方法与社会网络技术等对英语课程学期内7430条在线交互内容进行深度挖掘与全面分析。研究发现:知识创造交互主题紧密围绕教学内容呈现动态变化规律,与社交网络节点位置显著相关,且具有长度适中、深度差异以及概率明显等特点。With the support and deepening of connectivity technology and constructivism theory, learners have dual roles of knowledge consumers and knowledge producers in online learning. Where knowledge creation is regarded as the important learning activities. Although theories and models of knowledge creation are emerging a quantitative method on the process of knowledge creation is still lacking. Therefore, in terms of topic “artifact”, this study based on the theory of knowledge creation metaphor, introduced topic extraction method and social network technology to conduct in-depth mining and comprehensive analysis of 7430 online interactive content in an English course that lasts a semester. It is found that learners’ interaction topics during knowledge creation is closely around the teaching content and presents the dynamic change law, also significantly related to the location of the social network, and interaction topics have the characteristics of moderate length, different depths, and obvious probability.
