THE IMPORTANCE OF THE CAPES SCIENTIFIC DATABASE FOR THE BRAZILIAN AND WORLD RESEARCH

The Portal of Periódicos CAPES (PPC), created in the 2000's, has an agreement with 39,000 scientific journals, which allows it to be a broad and secure database for accessing scientific articles in the most diverse fields. The Portal provides access to 390 databases/collections, including national and international data, digital libraries and repositories, and journal collections. There are 13 scientific categories in the Portal, the most important being Multidisciplinary, followed by Engineering, Applied Social Sciences, and Exact and Earth Sciences. The Portal of Periódicos CAPES allows one to apply different filters to perform searches, what facilitates finding suitable articles for systematic reviews, for example. Thus, this study aimed to determine the performance of the PPC by measuring the number of retrieved scientific documents in comparison to other databases (e.g., PubMed, Redalyc, and SciELO). For that, five analyzes were carried out using certain descriptors and a time interval of published articles. By doing so, a larger number of queries resulted from the CAPES Portal in respect to the databases investigated, characterizing it as a powerful tool for the audience interested in searching and recovering high quality scientific documents, especially when compared with databases abroad (i.e., PubMed). Additionally, for further expansion and optimizations of the PPC, it is important that it be more and more valued, both nationally and internationally. For that, a greater dissemination of their contents and possibilities to the users, e.g., researchers, professors, and students, must be pursued, in addition to greater investments in research and development in the country.
