INTRODUCTION
• Evaluating scientific quality is a notoriously
difficult problem which has no standard
solution.
• Methods for evaluating research are being
sought, such as citation rates and journal
impact factors, h-index, g-index, Citation
Scores etc.,
H-index
• The h-index was developed by J.E. Hirsch and published in
Proceedings of the National Academy of Sciences of the
United States of America 102 (46): 16569-16572 November 15
2005.
• Calculating the h-index Value - The h-index factor is based
on the depth of your Web of Science subscription and your
selected time span. Items that do not appear on the Results page
will not be factored into the calculation. If your subscription
depth is 10 years, then the h-index value is based on this depth
even though a particular author may have published articles
more than 10 years ago. Moreover, the calculation only
includes items in Web of Science - books and articles in noncovered journals are not included.

G-index
• The g-index is an index for quantifying the scientific
productivity of physicists and other scientists based on their
publication record.
• It was suggested in 2006 by Leo Egghe. The index is calculated
based on the distribution of citations received by a given
researcher's publications.
• Given a set of articles ranked in decreasing order of the number
of citations that they received, the g-index is the (unique) largest
number such that the top g articles received (together) at least g2
citations.
g-index
Citation Map
• A Citation Map is a graphical representation that
shows the citation relationships (cited references and
citing articles) between a paper and other papers
using various visualization tools and techniques.
Using citation mapping, can analyze which
researchers are citing your papers and also choose
to organize and color code the results by author,
year, journal title, subject category, and more.

Sources for Data Collection
• The following Bibliographic Database will helps to
collect the data for Scientometric and Bibliometric
Study.

LISA and LISTA etc.,
Webometrics Tools
• Webometrics is (a) a set of quantitative
techniques for tracking and evaluating the
impact of web sites and online ideas and
• (b) the information science research field that
developed
these
ideas.
Webometric
techniques include link analysis, web mention
analysis, blog analysis and search engine
evaluation, but from the perspective of digital
library evaluation the main method is link
analysis.

GCS - Global Citation Score shows the total number of citations to a paper in the Web of
Science.
LCR - Local Cited References shows the number of citations in a paper's reference list to
other papers within the collection.
LCS - Local Citation Score shows the count of citations to a paper within the collection
NCR - Number of Cited References shows the number of cited references in the paper's
bibliography.
Recs - Number of Records shows the number of records where a given item is found.
T* - Total [score] Any Total score represents a sum of respected scores for all records
from a given author, source, other category, or all records

Conclusion
• Scientometric Study is one of the solutions for
measuring the scientific Publications.
• Once the Library Professional must familiar with
the above tools and techniques and make use for
measuring the Instructional Publications.
• This Presentation will helps to aware and know
the few measuring tools
