4 Why is this important H-index and citations useful for: CV evaluation at scientific evaluation for NCN grants finding potential collaborators interpretation of your work by other scientists Several reasons for citing: to provide background to provide related works to criticize or correct other works for self citations

6 Simple bibliometric methods number of papers number of citations number of papers in journals with IF Problem A single method is not sufficient to measure both productivity and impact!

7 Hirsch index (h-index) definition A scientist has index h if 1 h of his/her Np papers have at least h citations each, 2 and the other (Np - h) papers have no more than h citations each.

8 How to increase h-index? The citation number needed for increasing h-index source:

10 Other bibliometric methods Modifications of h-index g-index hb-index hc-index (contemporary h-index) hi-index (individual h-index) h(2)-index e-index (excess citations index) Much more:

11 G-index G-index definition Given a set of articles ranked in decreasing order of the number of citations that they had received, the g-index is the (unique) largest number such that the top g articles received (together) at least g 2 citation.

12 Where one can find some information about my papers? Selected scientific databases Web of Science (Thomson Reuters) Google Scholar (Google) Scopus (Elsevier) DBLP (University of Trier) Academic Search (Microsoft) Citeseerx (Penn State University) Arnetminer (Tsinghua University) SpringerLink (Springer) ACM Digital Library (ACM)
