Points to be Discussed
Institutional Repository (IR)
 Need of IR
 Research Questions
 Methodology
 Results
 Conclusion

Need of IR
To support Open Access Initiatives;
 To encourage the web publication;
 To archive institutional knowledge and
make it available through intranet;

Need for Webometric Ranking
To measure the global visibility and
impact of scientific repositories;
 To know the relative position of a
particular IR;
 To evaluate the present status of IR at
the state level, national level and at the
global level;

Research Questions
How does global visibility for institution’s
scholarship measure?
 Is it possible to find out the web presence of
Indian institutional repositories?
 How to develop the ranking system for Indian
institutional repositories?
 Is it possible to know highly used software in
Indian institutional repositories?

Methodology
Selection of Institutional Repositories
 Collection of URLs
 Selection of Search Engines
 Collection of Data
 Choice of Indicators for Ranking IR
 Normalization of Data
 Calculation of Rank Index

Selection of IRs

OpenDOAR: an authoritative directory of
academic open access repositories. There are
52 IRs . http://www.opendoar.org/

ROAR: 73 institutional repositories in India are
listed under Registry of Open Access
Repository. http://roar.eprints.org

Normalization of Data

Based on each indicator, all the selected IRs
are arranged in descending order of
magnitude and assigned a rank for them.
Calculation of Rank Index
Index Value may be calculated as:
20%.S + 40%.V + 15%.R + 15%.Sc +
5%.Ri + 5%.D
Where, S= Size,V= Visibility, Sc= Google
Scholar, Ri= Rich Files & D= Duration

Conclusion

To maximize the visibility of institution’s
research outputs.

The authors’ visibility increases if their
research outputs are available through open
access institutional repositories.

Institutional visibility increases resulting
into an increase in world rank of the
institutes.

IR may be at global level, institutional level
and departmental level.
