Abstract： [Purpose/significance] In order to enhance the practicability of thesaurus, it is necessary to constantly update new terms in the field to thesaurus. In the process of updating and maintenance, we should explore the distribution characteristics of new terms from the perspective of time and frequency, which can provide reference for the method of discovering new terms.[Method/process] Based on the relevant characteristics of the new terminology, combined with the development distribution of the corresponding document frequency at time point and period, through the relevant statistical analysis, the distribution of terminologies in different development periods is studied, especially the characteristics of terminologies from the beginning to the maturity.[Result/conclusion] It is proved that the new terminology is generally in the growth stage of terminology. When the candidate new terminology keeps positive growth trend for more than a certain number of years, it is considered that the term has all novelty, time persistence and terminological features. Based on the distribution characteristics, the article selects a subject area to discover its new terminology. According to the judgment of the expert, the method has a high accuracy rate in the judgment of new term, and can effectively identify the low frequency words which are more occupied in practical applications.
