“…Regarding overpricing detection, Correa and Leal [2018] apply ontology-based text mining and clustering techniques to unveil overpricing instances within the products procured by the federal government of Brazil, focusing specifically on medications procured by the Ministry of Health. The authors use such techniques to create a consolidated price base for each medication, which can be used as a benchmark against which current prices are compared.…”

Analyzing overpricing in public bidding items is essential for government agencies to detect signs of fraud in acquiring public goods and services. In this context, this paper presents two main contributions: a methodology for processing and standardizing bid item descriptions and a statistical approach for overpricing detection using the interquartile range. We evaluated a comparative analysis of three distinct grouping strategies, each emphasizing different facets of the item description standardization process. Furthermore, to gauge the efficacy of both proposed approaches, we leveraged a ground-truth dataset for a thorough evaluation containing quantitative and qualitative analyses. Overall, our findings suggest that the evaluated strategies are promising for identifying potential irregularities within public bidding processes.

“…Existe uma versão que utiliza o ambiente gráfico (SIAFI WEB) e é operacionalizado pela rede mundial de computadores, concomitantemente, com o sistema inicial em modo texto (SIAFI). Porém, o SIAFI WEB necessita do SIAFI (tela preta) para funcionar, já que ele "se alimenta" do banco de dados do mesmo (Correa & Leal, 2018).…”

Society has demanded public management models that are more efficient, effective and effective, but with transparency in its actions and accountability. This is where the importance of public financial administration and its management tools is revealed so that the federal government can work on accountability in public management. This paper theoretically analyzes the tools used by SIAFI, SIAFI WEB and Managerial Treasury. For this, we proceed to a comparative and purposeful analysis against the advantages and disadvantages of the tools in use. It can be seen that the Management Treasury can contribute in order to remedy the identified gap, as well as optimizing for public management to effectively achieve accountability.
