[Objective] This paper explores the granularity of Chinese terms from different fields, and then measures the Term Discriminative Capacity (TDC).[Methods] First, we used TDC to evaluate the quality of terms from four indexes. Then, we detected the differences in TDC among disciplines, fields and term granularity.[Results] In control group, the order of mean TDC was Title > Abstract > Keywords Plus > Keywords. In experimental group, the performance of Keywords Plus was improved, thus Title > Keywords Plus > Abstract > Keywords.[Limitations] We only collected data from five disciplines in Humanities and Social sciences.[Conclusions] Both Chinese term granularity and source fields influence the Term Discriminative Capacity. We should standarize term granularity to reduce the impact of fields.
