摘要
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.关键词
