The keyword frequency information plays an important reference value in the construction and application of thesaurus, to improve its practicality. Through research and practice, this paper summarizes three methods to use the keyword frequency information, which are to find the core concepts with keyword frequency and proportion, to determine the preferred words with it, and to give the category for the concept with it. This paper also discusses the level of vocabulary frequency properties, the importance of preferred words, the changes of keyword frequency life-cycle and the limitation of the word frequency.
Key words： keyword frequency; concept; thesaurus; preferred word; category number
