随着“大数据”在全球范围兴起,其关注度不断飙升,但关于人们对大数据的认知状况学术界缺乏比较深入的探讨。以新浪微博为抽样对象,分析“大数据”这一概念或话题在新浪微博语境中是如何被理解并传播的,具有当下的现实意义。为此,本文选取了一个样本周时段内新浪微博中有关“大数据”的文本,对这些样本进行分词、聚类分析和情感分析。同时,借助视觉化工具,构建“大数据”及其子群的微博社会语义网图谱,探讨“大数据”在社交网络中的认知现状及其面临的问题。
With the rise of “big data” around the world, its concern has been on the rise. However, there is a lack of deep discussion about the cognitive status of big data in academia. Taking Sina Weibo as a sampling object, it is of immediate practical significance to analyze how the concept of “big data” or topic is understood and disseminated in Sina Weibo context. To this end, this article selects the text of “Sina Weibo” in “Sina Weibo” in a sample week period, and performs word segmentation, cluster analysis and sentiment analysis on these samples. At the same time, with the aid of visual tools, we construct the social semantic network diagram of Weibo for “big data” and its subgroups, and discuss the current status and problems of “big data” in social networks.
