An Applied Research Of Word Frequency Analysis In "Hot Spot" Articles

Key words or subject words in a document are the refinement of the core content in one paper.Therefore,if a key word or subject word appears repeatedly in research literature in its field,it can be considered the research topic which the key words or subject words represent.In scientific research,researchers usually determine the research focus or development trend in one field by counting the frequency of keywords or subject words in the total sample.Word frequency analysis is one of the most commonly used literature analysis methods for researchers.At present,the research on word frequency analysis in our country can be divided into two categories: one is the perfection of it,that is,the improving and perfecting of itself,discussing the object word selection strategies and high frequency word selection methods.The other is the application research of word frequency,which is used to analyze the hot-spots in a filed,combined the word frequency analysis and others,such as Co-word analysis,multi-dimension analysis,knowledge mapping and etc,to explore the hot-spots and deep research topics.In contrast,the number of application articles of this kind is much higher than the former.Word frequency analysis,based on objective data,has high accuracy and reliability,is widely used in current situation,development trend,research topics,research hot-spots and so on.Nowadays,word frequency analysis has more widely used in academia.At the same time,it also brings new phenomena and problems in the application process.This paper takes "word frequency-hot spot" articles in China as the analysis object,carried out sampling statistical analysis,discusses the development status of such documents,the current situation of high-frequency word selection,the main research methods used in such articles and the evolution law of the methods used from the perspective of content analysis.By extracting the data from the sample literature,this paper summarizes three kinds of high frequency word selection methods commonly used in "word frequency-hotspot" articles in China,and makes a comparative experiment on the three main methods of high frequency word selection.It concludes that there are obvious subjectivity in high frequency word selection in China at this stage,the principle of the method used is not clear,the formula of defining high frequency words and low frequency words is applied,and Price Gong.The applicability of the formula is undetermined.In chronological order,this paper divides the evolution process of the research methods used in "word frequency-hot spot" articles into two stages,sorts out the changes and characteristics of their writing modes in different stages,and points out the existing problems of solidification of writing modes.By combing and comparing the diffusion process of "word frequency-hotspot" articles among different disciplines,this paper summarizes the characteristics,scope and change of diffusion rate of interdisciplinary diffusion.From this,it is concluded that there are many problems in the "word frequency-hot spot" articles in China,such as emphasizing practice and neglecting theory,which can be reflected in the selection and application process of the method,as well as in the data processing and analysis after the application method.It is hoped that through the analysis of this paper,we can provide some useful directions for the future development and research of "word frequency-hotspot" articles in China,and promote the benign development of such articles and research.
