It is possible to try the predictions using an online tool. The h-index serves as an alternative to more traditional journal metrics in the evaluation of the impact of the work of a particular researcher. The h-index is intended to measure simultaneously the quality and quantity of scientific output. Scopus has better coverage of conferences, but poor coverage of publications prior to 1996; Google Scholar has the best coverage of conferences and most journals though not all , but like Scopus has limited coverage of pre-1990 publications. However, this finding was contradicted by another study by Hirsch.

The index can also be applied to the productivity and impact of a as well as a group of scientists, such as a department or university or country. Among 36 new inductees in the National Academy of Sciences in biological and biomedical sciences in 2005, the median h-index was 57. A scientific institution has a successive Hirsch-type-index of i when at least i researchers from that institution have an h-index of at least i. For the economic measure, see. It has been stated that citation behavior in general is affected by field-dependent factors, which may invalidate comparisons not only across disciplines but even within different fields of research of one discipline.

During the period January 1, 2000 — February 28, 2010, a physicist had to receive 2073 citations to be among the most cited 1% of physicists in the world. First we order the values of f from the largest to the lowest value. One can be easily convinced that ranking in coauthorship networks should take into account both measures to generate a realistic and acceptable ranking. When compared with a video creator's total view count, the h-index and g-index better capture both productivity and impact in a single metric. The h-index is an that attempts to measure both the and of the of a or scholar.

This article is about the index of scientific research impact. Thus, the true predictability of future h-index is much lower compared to what has been claimed before. What is a H file? Hirsch has demonstrated that h has high predictive value for whether a scientist has won honors like membership or the. Journal of the American Society for Information Science and Technology. Scientists with high h 2 upper percentages are perfectionists, whereas scientists with high h 2 lower percentages are mass producers.

A value of about 18 could mean a full professorship, 15—20 could mean a fellowship in the , and 45 or higher could mean membership in the. Each database is likely to produce a different h for the same scholar, because of different coverage. Biochemical and Biophysical Research Communications. However, later work has shown that since h-index is a cumulative measure, it contains intrinsic auto-correlation that led to significant overestimation of its predictability. For example, if we have a researcher with 5 publications A, B, C, D, and E with 10, 8, 5, 4, and 3 citations, respectively, the h-index is equal to 4 because the 4th publication has 4 citations and the 5th has only 3.

Numbers are very different in social science disciplines: The Impact of the Social Sciences team at found that social scientists in the United Kingdom had lower average h-indices. It was found that the distribution of the h-index, although it depends on the field, can be normalized by a simple rescaling factor. Of course this method does not deal with academic age bias. A detailed study showed that the Web of Science has strong coverage of journal publications, but poor coverage of high impact conferences. A successive Hirsch-type-index for institutions has also been devised.

The h-index has been applied to Internet Media, such as channels. As these metrics are percentages, they are intended to give a qualitative description to supplement the quantitative h-index. Journal of the American Society for Information Science and Technology. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications. From July 2011 have provided an automatically-calculated h-index and within their own profile.

In contrast, if the same publications have 25, 8, 5, 3, and 3 citations, then the index is 3 because the fourth paper has only 3 citations. It might be simpler to divide citation counts by the number of authors before ordering the papers and obtaining the h-index, as originally suggested by Hirsch. Should you later decide to change the name, you only have to do it in the header file and recompile to make the change take effect everywhere. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files. For example, the Meho and Yang study found that Google Scholar identified 53% more citations than Web of Science and Scopus combined, but noted that because most of the additional citations reported by Google Scholar were from low-impact journals or conference proceedings, they did not significantly alter the relative ranking of the individuals. It has been suggested that in order to deal with the sometimes wide variation in h for a single academic measured across the possible citation databases, one should assume false negatives in the databases are more problematic than false positives and take the maximum h measured for an academic. It was introduced in July 2011 by as part of their work on.

However, Hirsch noted that values of h will vary between different fields. Because only the most highly cited articles contribute to the h-index, its determination is a simpler process. For example, if you define a text string with your company name in a header file, this constant can be used everywhere you need to display or otherwise use the company name in your source code. The exclusion of conference proceedings papers is a particular problem for scholars in , where conference proceedings are considered an important part of the literature. Subscription-based databases such as and the provide automated calculators. Then, we look for the last position in which f is greater than or equal to the position we call h this position.

The three h 2 metrics measure the relative area within a scientist's citation distribution in the low impact area, h 2 lower, the area captured by the h-index, h 2 center, and the area from publications with the highest visibility, h 2 upper. In addition, specific databases, such as the database can automatically calculate the h-index for researchers working in. Harzing's Publish or Perish program calculates the h-index based on entries. They may contain constants, function prototypes and external variable definitions. If you have additional information about the H file format or software that uses files with the H suffix, please do - we would love hearing from you.
