It is to say that the selection of high-frequency word determines the results of word frequency analysis, impacts the whole analysis program. First, the paper cleared up the nearly three years papers in China by using word frequency analysis method for hot spots analysis, and found four common classes selections of high-frequency word methods mainly include:the author set the selection method, Donohue's formula selection, price formula selection and mixed selection. Secondly, we use the literature of personal knowledge management as the research object, and calculate the frond three kinds of high frequency words selections respectively, and compare the results with clustering analysis, then we discuss the effect and applicability of high-frequency word threshold selection on the analysis results. At last, the paper pointed out that there were some problems, such as the subjective is high, principle is unclear, improved methods' principle is unclear, the Donohue's formula and price formula's applicability are stil unsure, in the study of high-frequency word threshold selection in our country.关键词
