摘要:
 为了对舆情的研究现状进行客观梳理，总结研究文献内在的联系和科学结构，文中选取近5年来中国知网收录的“中文核心期刊”和“CSSCI”相关研究文献展开研究。首先，进行前期数据准备，包括准备的步骤与方法及其相关的数学模型；然后，将相异系数矩阵输入到SPSS中进行多维尺度分析并绘制知识图谱；最后，从维度定义和空间分布特点两个方面对知识图谱进行分析。结果表明，当前舆情研究主要集中于4个方向，舆情直接相关研究是重点与热点，媒体相关的研究领域也较活跃，但一些细分的研究方向成果比较分散。
Abstract:
 In order to conduct objective comb for the current situation of public sentiment research and summarize the intrinsic links and science structure of researched literatures,it researches on"Chinese Core Journals" and"CSSCI" relevant research literatures included in CNKI in the past five years in this paper. First,preliminary data should be prepared,comprising the steps and methods of preparation and associated mathematical model. Then,the dissimilarity coefficient matrix is input into SPSS software to carry on multi dimensional scaling and draw mapping knowledge domain. Finally,mapping knowledge domain must be analyzed from two aspects of dimension definition and spatial distribution. The results show that the current public sentiment research has focused on four directions,and direct relevant re-search of public sentiment is the focus and hotspot,and media-related field of study is more active,but some results of research direction of segmentation are more dispersed.
