Metrics: A profusion of measures: Scientific performance indicators are proliferating — leading researchers to ask afresh what they are measuring and why. Richard Van Noorden surveys the rapidly evolving ecosystem.
In June 2013, the Alfred P. Sloan Foundation awarded NISO a grant to undertake a two-phase initiative to explore, identify, and advance standards and/or best practices related to a new suite of potential metrics in the community. This project is an important step in the development and adoption of new assessment metrics, which include usage-based metrics, social media references, and network behavioral analysis. In addition, this project will explore potential assessment criteria for non-traditional research outputs, such as data sets, visualizations, software, and other applications.
Oxford Internet Institute: University of Oxford There are three main sources of bibliometric data: Web of Science, Scopus, and Google Scholar. Each has certain advantages and limitations which may influence which source or combination of sources you decide to use in your bibliometric search.
The SCImago Journal & Country Rank is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database (Elsevier B.V.). These indicators can be used to assess and analyze scientific domains.
