Abstract
The growing computational power facilitates much demanded comparative and relative study of publication output, journal impact, and collaborative publications. This significant growth of data, its availability, and easy access has given rise to the range of metrics and indicators which are applied at different levels of research assessment. These indicators are available to measure the quality and impact of the research output at individual, institutional, or national level. The availability of these indicators has highlighted their application depending upon the aim and subject of assessment and evaluation of research.
