J Scientometric Res. | May-Aug 2016 | Vol 5 | Issue 2 135 RESEARCH ARTICLE JSCIRES ABSTRACT Impact factors and citation indices are used to evaluate the impact Research publications .There are several citation indices that are proposed and existed to assess the value of a research publication or the research impact of an author or a journal. In this paper, a survey of selected (evolutionary basis) citation indices is conducted to evaluate them. Using examples, we demonstrated some of the limitations and problems with those indices. It is observed that h-index and m-quotient fails to differentiate among the authors having different citation count and hit papers. The flaw is rectified by A-index, M-index and R-index. A-index more closely ranks the authors on the basis of hit papers and highest no. of Average Citation per Paper (ACPP). Thus among the selected citation indices A-index is considered as best to rank the authors on the basis of their hit contributions in the field. However the study is open to future research by putting more and recently evolved citation indices into test and comparison within the researchers of same field or from diverse fields. There is a need for more sensitive and comprehensive citation indices that can take into considerations all the factors that may impact a research publication or author and looks beyond the h-core. Key words: Impact Factor, h-index, h-index variants, a-index, g-index, m-index, m-quotient Assessing Impact of Citation Laureates Using Improved Dimensions of h-index Rosy Jan, Aaqib Mir, Ryhana Assad Department of Library and Information Science University of Kashmir, INDIA. for accountability in Higher Education has led govern- ments, research authorities and University administrators to assess research performance using multiple indices that allow comparisons and rankings. 1 In the last few years, several research and publication papers related to research indices were proposed to assess the quality of the academic research publications started in the year 2005 when harsh proposed h-index. Many funding agencies use the metrics to evaluate institutional performance, compounding the problem. 2 While using h index to measure the quality of the research experts found some defciencies. 3 “In certain cases, the mechanism used by the h-index to aggregate publication and citation statistics into a single number leads to inconsistencies in the way in which scientists are ranked. Our conclusion is that the h index cannot be considered an appropriate indicator of the overall scientifc impact of a scientist”. 4 “Situation which questions the use of the h-index is that concerning those scientists who attain a similar h-index result and yet have different total citation counts”. There is no logical connection between number of citations and publication sequence. New authors have a problem with H-index as they have no or low index value due to time constraints. H-index does not take the actual number of citations; the content of H-core is not sensitive with more citations. 5 *Address for correspondence: Rosy Jan, Senior Assistant Professor, Department of Library and Information Science, University of Kashmir, INDIA.

Identifying high quality science is important, but to measure the quality of the science has become even more important. The need
