H File

The h-index has been applied to Internet Media, such as channels. First we order the values of f from the largest to the lowest value. May not be redeemed for cash or cash equivalent and is not transferable. Thus, the true predictability of future h-index is much lower compared to what has been claimed before. The index is designed to improve upon simpler measures such as the total number of citations or publications. This method has not been readily adopted, perhaps because of its complexity. No adjustments on prior purchases.

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. As these metrics are percentages, they are intended to give a qualitative description to supplement the quantitative h-index. The h-index is intended to measure simultaneously the quality and quantity of scientific output. A detailed study showed that the Web of Science has strong coverage of journal publications, but poor coverage of high impact conferences.

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. This improvement can enhance the measurement sensitivity of the h-index. 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. For the economic measure, see.

h

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. The header files are included by source code files that need to use the constants or functions defined in the header file. It was found that the distribution of the h-index, although it depends on the field, can be normalized by a simple rescaling factor. It was introduced in July 2011 by as part of their work on. The h-index is an that attempts to measure both the and of the of a or scholar. For Loyalty Members only: offer combinable with one Membership offer or reward.

Hirsch has demonstrated that h has high predictive value for whether a scientist has won honors like membership or the. 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. Each database is likely to produce a different h for the same scholar, because of different coverage. In addition, specific databases, such as the database can automatically calculate the h-index for researchers working in. 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. The exclusion of conference proceedings papers is a particular problem for scholars in , where conference proceedings are considered an important part of the literature.

A successive Hirsch-type-index for institutions has also been devised. 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. They may contain constants, function prototypes and external variable definitions. 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. This article is about the index of scientific research impact. It is possible to try the predictions using an online tool.

Because only the most highly cited articles contribute to the h-index, its determination is a simpler process. Journal of the American Society for Information Science and Technology. . 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. Yes, email me my member rewards, special invites, trend alerts and more. 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.

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. Therefore, these disciplines have lower citation thresholds in the Essential Science Indicators, with the lowest citation thresholds observed in social sciences 154 , computer science 149 , and multidisciplinary sciences 147. The index was suggested in 2005 by , a physicist at , as a tool for determining ' relative quality and is sometimes called the Hirsch index or Hirsch number.

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. However, this finding was contradicted by another study by Hirsch. 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. Your inbox is about to get a lot more stylish! 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. On average across the disciplines, a professor in the social sciences had an h-index about twice that of a lecturer or a senior lecturer, though the difference was the smallest in geography. Harzing's Publish or Perish program calculates the h-index based on entries.
