RESEARCH METRICS
It is the quantitative analysis of scientific and scholarly outputs and their impacts. Research Metrics measure impact and provide insight into the influence of specific journal publications, individual articles, and authors.

1. RESEARCH METRICS:
It is the quantitative analysis of scientific
and scholarly outputs and their impacts.
Research Metrics measure impact and
provide insight into the influence of
specific journal publications, individual
articles, and authors.
Research Metrics involve:
Journal Impact Factor
h-index
i10-index
2. h-INDEX
The definition of the index is that a
scholar with an index of h has
published h papers each of which has
been cited in other papers at
least h times.
CHARACTERISTICS:
The h-index reflects both the number of
publications and the number of citations per
publication.
The index is designed to improve upon simpler
measures such as the total number of citations
or publications.
The index works properly only for comparing
scientists working in the same field.
3. ADVANTAGES:
The h-index was intended to address the main
disadvantages of other bibliometric indicators,
such as total number of papers or total number
of citations.
It simultaneously measures the quality and
sustainability of scientific output, as well as, to
some extent, the diversity of scientific research.
DISADVANTAGES :
Like impact factors it depends on subject area.
It does not show the current activity or inactivity
of the author.
Disadvantageous for younger researchers.
Scientists with short scientific life are out of
competition.
4. i10-INDEX
The i10-index indicates the number of
academic publications an author has
written that have at least ten citations
from others.
It was introduced in July 2011
by Google as part of their work
on Google Scholar.
CHARACTERISTICS:
i10-index= the number of publications with at
least 10 citations
It is another way to help gauge the
productivity of a scholar.
It is used in Google's My Citations feature.
5. ADVANTAGES:
It is very simple and straightforward to
calculate.
My Citations in Google Scholar is free
and easy to use.
DISADVANTAGES:
It is used only in Google Scholar.
Its pan-national recognition is not as
high as h-index.
Conclusion:
h-index and i10-index are very helpful in quantitative
analysis of research work done by different
scientists in the same field and also help in
comparing the work of different scientists or author.
