Scholar Metrics - New kid on the block
- Scholar Metrics currently cover articles published between 2007 and 2011, both inclusive. The metrics are based on citations from all articles that were indexed in Google Scholar as of November 15th, 2012. This also includes citations from articles that are not themselves covered by Scholar Metrics.
- The h-index of a publication is the largest number h such that at least h articles in that publication were cited at least h times each. For example, a publication with five articles cited by, respectively, 17, 9, 6, 3, and 2, has the h-index of 3.
- The h-core of a publication is a set of top cited h articles from the publication. These are the articles that the h-index is based on. For example, the publication above has the h-core with three articles, those cited by 17, 9, and 6.
- The h-median of a publication is the median of the citation counts in its h-core. For example, the h-median of the publication above is 9. The h-median is a measure of the distribution of citations to the articles in the h-core.
- Finally, the h5-index, h5-core, and h5-median of a publication are, respectively, the h-index, h-core, and h-median of only those of its articles that were published in the last five complete calendar years.
Scholar Metrics only includes publications with at least a hundred articles in the last five years.
Scholar Metrics summarise recent citations to many publications, to help authors as they consider where to publish their new research.
To get started, you can browse the top 100 publications in several languages, ordered by their five-year h-index and h-median metrics. To see which articles in a publication were cited the most and who cited them, click on its h-index number to view the articles as well as the citations underlying the metrics.
You can also explore publications in research areas of your interest. To browse publications in a broad area of research, select one of the areas in the left column. For example: Engineering & Computer Science or Health & Medical Sciences.
To explore specific research areas, select one of the broad areas, click on the "Subcategories" link and then select one of the options. For example: Databases & Information Systems or Development Economics.
Browsing by research area is, as yet, available only for English publications. You can, of course, search for specific publications in all languages by words in their titles.
