在进行一项研究之前,我们必须对该领域的研究动态与发展趋势了如指掌。因此,研究述评必不可少。研究述评不应该只是某些专家学者的专利,而应成为每一个研究者必备之能力。如何建构一套科学的述评综合评价指标体系对每一个研究者来说都至关重要。研究述评的目的在于用最精简的语言呈现出该领域相关研究的全貌。一般先科学地确定主题,再分别针对同一主题的不同研究成果进行“陈述”和“评论”。我们可采用三种计量方法来确定主题:一是单纯的主题词统计、排序,得出研究的热点,这种方法简单易行,但不能挖掘出主题词之间的关系;二是共词聚类法(Co-word Cluster),共词聚类是对当前发表文献的直接统计,反映的是目前已有论文所集中关心的主题,它不仅寻求高频率出现的词,更注重这些词之间的联系,从而更好地反映主题之间的关系;三是同被引(Co-citedCluster)聚类法,通过对以往发表的论文的引用情况表现人们目前关注的焦点。但是,我国媒体发展研究缺乏引文索引工具,此法也难以顺利实现。
Before conducting a study, we must be well aware of the research trends and trends in the field. Therefore, the research review is essential. The research review should not be just a patent for some experts and scholars, but should be the essential ability of every researcher. How to Construct a Set of Scientific Commentary The comprehensive evaluation index system is of crucial importance to every researcher. The purpose of the research review is to present the full picture of the relevant research in this field in the most condensed language. Generally, the subject is determined scientifically first and then “statement” and “comment” are respectively made for different research results of the same subject. We can use three kinds of measurement methods to determine the theme: one is the simple statistics of the subject, sorting, come to the study of hot spots, this method is simple and easy, but can not mine the relationship between the keywords; second is the total poly Co-word Cluster, co-word clustering is a direct statistics on the current published literature, reflecting the theme of the current papers have focused on, not only to find high-frequency words, pay more attention to these words Thirdly, we use the Co-cited Clustering clustering method to express the current focus of attention by quoting the previously published papers. However, the lack of citation indexing tools in China’s media development research can hardly be achieved smoothly.
