2 Workshop Objectives Scientometrics: Basics Citation Databases Scientometrics Indices H-index, M-index, G-index Journal Impact Factor Journal Citation Reports CiteScore, SNIP, SJR Citation Analysis: ISI, Scopus 2

3 Definition Scientometrics is the study of measuring and analyzing science, technology and innovation.

4 History Modern Scientometrics is mostly based on the work of Eugene Garfield creator and founder of the Science Citation Index and the Institute for Scientific Information (ISI) which is heavily used for scientometric analysis. Leydesdorff, L. and Milojevic, S., "Scientometrics" in: Lynch, M. (editor), International Encyclopedia of Social and Behavioral Sciences subsection (2015)

24 Types of Scientometric Indices Quantitative Indices Qualitative Indices Quantitative-Qualitative Indices

25 Scientometric Indices: Levels of application Authors Number of papers (Quantity) Number of Citations (Quality) Average number of Citations or Citation/Paper (Quantity & Quality) H-index & g-index (Quantity & Quality) Journals Number of papers (Quantity) Number of Citations (Quality) Journal Impact Factor, h-index (Quantity & Quality) Articles Number of Citations (Quality)

26 Scientometrics Indices Scientific Productivity Citations Immediacy Index Cited half life Highly Cited Paper H-Index M-Index (m<h) G-Index (g>h)

27 H-Index The h-index was suggested in 2005 by Jorge E. Hirsch, an American physicist. The h-index is a measurement that aims to describe the scientific productivity and impact of a researcher. The h-index is defined by how many h of a researcher s publications each have at least h citations.

28 H-Graph

29 Journal Impact Factor (JIF) Journal impact factor was devised by Eugene Garfield, the founder of the ISI to compare journals JIFs are calculated yearly starting from 1975.

30 Journal Impact Factor: Definition The average number of citations received in a year by articles published in that journal during the two preceding years.

31 JIF Calculation Journal A published some papers in 2014 & 2015: Item Total Total Papers Published Citations Achieved in

32 Immediacy Index All Previous Years Cited ½ Life Impact Factor Citation Source paper published in 2012 Cited reference published in 2012 Cited reference published in 2010 or 2011

33 Journal Citation Reports (JCR) Journal Impact Factors are calculated and released annually by one of the most important and useful ISI databases called Journal Citation Reports.

34 Example NURSING RESEARCH IF 2015 = BONE RESEARCH IF 2015 = IMMUNOLOGY IF 2015 = 4.078

35 CiteScore CiteScore is the new journal evaluation metrics proposed by Elsevier. The concept is the same as Impact Factor. It's a 3 years period of time index

36 SCImago vs JCR Source of data Coverage Algorithm Access Application

37 SCImago Journal Rank (SJR) SJR is normalized by the total number of citations in the citing journal for the year in question. Each journal is a node and each directed connection is a normalized value of the number of citations from one journal to another over a three year window.

38 Source Normalized Impact Per Paper (SNIP) SINP normalizes the different fields based on the citing-side form of normalization, rather than normalizing with respect to the just total citations a journal receives. SINP normalizes with respect to the number of references in the citing journals.
