Altmetrics and Other Novel Measures for Scientific Impact


Impact assessment is one of the major drivers in scholarly communication, in particular since the number of available faculty positions and grants has far exceeded the number of applications. Peer review still plays a critical role in evaluating science, but citation-based bibliometric indicators are becoming increasingly important. This chapter looks at a novel set of indicators that can complement both citation analysis and peer review. Altmetrics use indicators gathered in the real-time Social Web to provide immediate feedback about scholarly works. We describe the most important altmetrics and provide a critical assessment of their value and limitations.
