V-index an index based on consistent researcher productivity

In the current era, tremendous amount of scientific research work is published by thousands of researchers annually. Different methods have been proposed for researcher productivity indexing based on quantity and quality of publications. Unfortunately, none of them considered the variation among the number of citations received by a researcher for his papers. In this paper, a novel method named Variation-Index (v-index) is proposed to handle this issue. It will consider variation in number of citations received by the researcher´s publications. V-index considers the consistency in citations of researcher´s publication in addition to their number of publications (quantity) and number of citations (quality) for indexing. Experimental results show the effectiveness of our proposed v-index over the existing state of the art indexing methods. This citation variation enhancement is quite general and can be merged in any of the existing indexing measures with ease.
