摘要：The keywords provided by authors in their scientific articles and the descriptors assigned to those articles in various databases are analysed to find out the role played by these keywords during the indexing process. In order to do that, 108 periodical publications proportionally distributed between Social Sciences and Humanities (36 journals), Science and Technology (36) and Medical and Health Sciences (36) were selected. Ten articles were selected from each of the 108 journals from different years, so that we worked altogether on 1080 articles meeting two conditions: including keywords and being indexed in the databases ISOC, ICYT or IME. Then, we proceeded to draw a comparison between the keywords used by the authors of the 1080 articles with the descriptors assigned by the database indexers. The comparison shows that in IME database 64.96% of the keywords provided by the authors exactly coincide with the descriptors or just do so after normalization; 60.48% in ISOC and 58.18% in ICYT.
