On The Accuarcy of H-index Seifedine Kadry School of engineering and technology American university of the Middle East Egaila, Kuwait Abbass Lakkis, Ali Kalakech MIS department, Faculty of Business Lebanese University Beirut, Lebanon Abstract— to have a better quantification of an in individual scholar’s citation contact, many measures have been developed. Due to the measures that indicate the quality of researchers and organizations, the h-index has received a huge attention. By definition H-index is a positive integer number, hence the difficulty to compare two different scientists having same H- index but different number of articles published and citations. The goal of this paper is to develop a new formula that transform H-index from integer into decimal number in order to give more accurate and clear comparison among different scientists having same H-index. Keywords- Scientometric; citations, impact factor, H-index. I. INTRODUCTION The twentieth century may be described as the century of the development of metric science. Among the different metrics Scientometrics is the most interesting subject area in the field of library and information science, which can be applied to any discipline irrespective of their period of evolution. It involves quantitative studies of scientific activities. It is also one such useful metrics/technique which helps to solve the problems, challenges posed by so called information explosion. Over the years, several new terms have appeared in library and information science. They were known as:  Librametrics (1940’s) [1]  Bibliometrics (1960’s) [2] Bibliometrics as “the study of the use of documents and patterns of publication in which mathematical and statistical methods have been applied.”  Informetrics was used as a generic term to mean the use and development of a variety of measures to study and analyze several properties of information in general and documents in particular. “It covers Bibliometrics and scientometrics” [3].  Webometrics / Cybermetrics [4] as the study of the quantitative aspects of the construction and use of information resources, structure and technologies on the www drawing on bibliometrics and informetric approaches [14]. II. WHAT IS SCIENTOMETRICS ? Scientometrics is the quantitative study of science output or outcome in any form, not just records or bibliographies. It comprises all the metrics studies related to science indicators, citation analyses, research evaluation, etc. According to [5] “Scientometrics is defined as the quantitative study of science and technology”. Scientometrics involves studies in:  History of science.  Growth of Science and Scientific institutions.  Behavior of science and scientists.  Science policy and decision indicators. Where scientometrics started as Eugene Garfield's idea of an index to improve information retrieval in the 1960s and resulted in the creation of the Science Citation Index (SCI) was soon recognized as a novel instrument in the empirical study of the sciences. The availability of output indicators (such as databases of publications and patents). The term Scientometrics originated as a Russian term for the application of quantitative methods to the history of science. This term was introduction and came into prominence with founding of the journal named 'Scientometrics' It deals with analysis, evaluation and graphic representation of science and technology information and used to mean communication process in science including social- culture and appears to be almost synonymous to science of science so scientometrics is a part of the sociology of science and has application to science policy making. A. Scientometrics: Online Databases Data which are used to study scientometrics be retrieved from one of the following sources (web of science, Scopus and scholar Google ) web of Science database contains mainly journal publications, covers over 10,000 of the impact journals worldwide, including Open Access journal and over 110,000 conference proceedings and the Scopus is an international database. It's easy, quick and comprehensive to find the information scientists need. Contains 41 million records, 70% with abstracts, nearly 18,000 titles from 5,000 publishers worldwide, includes over 3 million conference papers, offers sophisticated tools to track, analyze and visualize research. While Google Scholar finds different types of sources, including journal papers, conference papers, books, theses and reports [6].
