It is estimated that more than 16,000 scientific journals use a thesaurus for the standardization of terms. Within this field, thesaurus are known for their functionality in the retrieval of information as well as in the search for specific terms, thus facilitating the refinement of the results and detailed comparisons of the categories. Therefore, the idea of ​​integrating a thesaurus in a scientific journal, not only benefits the editors, but also the authors themselves, managing to locate publications under the same theme that can serve as bibliographic support, ideas for future research and suggestions regarding the limitations of the study.
