Applying H-index within 5-year citations window

Abstract

There are a number of indexes proposed in many studies to evaluate the quality of journals. Among them, H-index is a recently proposed index as a useful supplement to journal impact factor. However, current H-index is based on long journal history. Immediate changes of citations of journals are often ignored by H-index. In this paper, we propose 5-year H-index to solve this problem. 5-year H-index evaluates the immediate citation performance (in this year) of a journal's papers published in the last 5 years. We can measure journals by the recent citations with 5-year H-index, which can be a new way to determine the value of journals.
