Altmetrics and its use in the evaluation of scientific research
Květ, Jonáš ; Dvořák, Jan (advisor) ; Šlosar, David Jiří (referee)
The diploma thesis deals with the field of altmetrics. The first part introduces the reader to the theoretical background of this field and discusses the development of scientific communication which enabled the emergence of altmetrics. The following part describes the benefits of implementation of altmetrics in research assessment, and includes the explanation of the limits and various obstacles that will need to be overcome in the future. The theoretical part of the thesis also deals with currently available tools that facilitate altmetrics collection. The practical part consists of the analysis of altmetric indicators and their comparison with traditionally used citations. The main focus of this part is on the coverage of the most used altmetric aggregators, on the correlation between citations and individual indicators, and also on what change in the coverage and values of indicators will bring the time interval of two months between data collections. Finally, using statistical methods, the thesis attempts to answer the question of which factors increase the chances of obtaining higher values of individual indicators. The research was conducted on documents with affiliations to institutions in the Czech Republic which are available in the Web of Science database for the period of 2017 to 2021.
