Total number of papers does not account for the quality of scientific publications, while total number of citations can be disproportionately affected by participation in a single publication of major influence for instance, methodological papers proposing successful new techniques, methods or approximations, which can generate a large number of citations , or having many publications with few citations each. 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. Of course this method does not deal with academic age bias. The exclusion of conference proceedings papers is a particular problem for scholars in , where conference proceedings are considered an important part of the literature. In addition, specific databases, such as the database can automatically calculate the h-index for researchers working in. Hirsch has demonstrated that h has high predictive value for whether a scientist has won honors like membership or the. First we order the values of f from the largest to the lowest value.

This improvement can enhance the measurement sensitivity of the H-index. 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. Biochemical and Biophysical Research Communications. 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. . This article is about the index of scientific research impact.

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.

For the economic measure, see. 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. 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. 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. 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. It was introduced in July 2011 by as part of their work on.

Whatever your preference, we can accommodate it better than anyone else in Omaha, Nebraska. 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. 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. Associated Press Stylebook says that a his­toric event is an impor­tant occur­rence, one that stands out in history. In contrast, if the same publications have 25, 8, 5, 3, and 3, then the index is 3 because the fourth paper has only 3 citations.

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. Tax, title, and license not included. From July 2011 have provided an automatically-calculated h-index and within their own profile. The h-index is intended to measure simultaneously the quality and quantity of scientific output. 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.

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. Harzing's Publish or Perish program calculates the h-index based on entries. The index is designed to improve upon simpler measures such as the total number of citations or publications. Perhaps something in the middle is more your speed, like the. Archived from on 5 May 2010.

However, Hirsch noted that values of h will vary between different fields. Tax, title, and license not included. Just do your best to be a good com­mu­ni­ca­tor and move on! One can be easily convinced that ranking in coauthorship networks should take into account both measures to generate a realistic and acceptable ranking. As these metrics are percentages, they are intended to give a qualitative description to supplement the quantitative h-index. Tax, title, and license not included.

The index works properly only for comparing scientists working in the same field; citation conventions differ widely among different fields. A detailed study showed that the Web of Science has strong coverage of journal publications, but poor coverage of high impact conferences. Scientists with high h 2 upper percentages are perfectionists, whereas scientists with high h 2 lower percentages are mass producers. Are you looking for a blast of efficiency? It is possible to try the predictions using an online tool. 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. 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.

It was found that the distribution of the h-index, although it depends on the field, can be normalized by a simple rescaling factor. This method has not been readily adopted, perhaps because of its complexity. 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. 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. Examples: a his­toric occa­sion — an X-Files episode.
