This study proposes a method for assessing the impact of scientific communication on their citation paths beyond conventional direct citations. The proposed method considers the contribution of scientific communication to their nth generation citations as a basis for calculating residual citations. Residual citations that are lost due to citation p...

Scientific retraction practices are intended to help purge the continued use of flawed research and assist in maintaining the integrity, credibility and quality of scientific literature. However, the practical effect of retraction is still vague and needs to be further explored. In this study, we analysed the citation counts and sentiments (positiv...

This article proposes an approach for allocating residual citations to scientific publications and demonstrating this proposed approach with a sample of biomedical publications.
