Web Impact Metrics for Research Assessment
Overview: Web metrics are being increasingly explored in the assessment research impact. Hyperlinks, web citations, and URL citations can today be systematically compared with conventional measures (e.g., Web of Science citation counts). Formal citations are also being extracted from web databases and digital libraries by CiteSeer, Google Scholar, and from the huge digitized database of Google Books. These may prove informative as alternative and supplementary citation impact metrics, especially in the social sciences, arts and humanities, where traditional citation indexes are not available or have insufficient coverage. New web impact metrics come from citations in online syllabi and course reading lists, which reflect the educational impact of research, and from download counts of academic publications, which reflect reading and usage. Social impact metrics or Altmetrics — including social bookmarks, tweets, online reading of scientific publications, and viewings of online academic videos — are also emerging. Web impact metrics need to be used cautiously in research evaluation, however, because they still suffer from a generic lack of quality control compared with traditional citation metrics.
