Center hyperedge (induced by source paper "measuring field normalized impact of papers on specific societal groups an altmetrics study based on mendeley data"):
  Abstract: Bibliometrics is successful in measuring impact because the target is clearly defined: the publishing scientist who is still active and working. Thus, citations are a target-oriented metric which measures impact on science. In contrast, societal impact measurements based on altmetrics are as a rule intended to measure impact in a broad sense on all areas of society (e.g. science, culture, politics, and economics). This tendency is especially reflected in the efforts to design composite indicators (e.g. the Altmetric Attention Score). We deem appropriate that not only the impact measurement using citations is target-oriented (citations measure the impact of papers on scientists) but also the measurement of impact using altmetrics. Impact measurements only make sense, if the target group—the recipient of academic papers—is clearly defined. Thus, we extend in this study the field-normalized reader impact indicator proposed by us in an earlier study, which is based on Mendeley data (the mean normalized reader score, MNRS), to a target-oriented field-normalized impact indicator (e.g. MNRSED measures reader impact on the sector of educational donation, i.e. teaching). This indicator can show—as demonstrated in empirical examples—the ability of journals, countries, and academic institutions to publish papers which are below or above the average impact of papers on a specific sector in society (e.g. the educational or teaching sector). Thus, the method allows to measure the impact of scientific papers on certain groups—controlling for the field in which the papers have been published and their publication year.
