A produção científica sobre qualidade de dados em big data

Abstract: Cada vez mais o tema big data tem despertado interesse em pesquisadores das mais diferentes áreas do conhecimento, entre eles os cientistas da informação que necessitam compreender seus conceitos e aplicações para poderem contribuir com novas propostas para a gestão das informações geradas a partir dos dados armazenado nestes ambientes. O objetivo deste artigo é apresentar um levantamento das publicações relacionadas a qualidade de dados em big data na base de dados Web of Science até o ano de 2016. Serão apre… Show more

“…To obtain the results, the first step was to simulate a search on Google about the diseases: DM, SAH, and dyslipidemia, which are the most recurrent subjects in a Primary Care office routine and that are probably the most accessed by medical students (Figure 1, 2, and 3, respectively). Strategies such as Google AdSense, an advertising service offered by Google and used by digital content producers, make it possible to individualize advertisements from the user's consumer profile which, in turn, is identified through statistical data analysis such as BigData (FAGUNDES et al, 2018). It is known that the search for a content in databases is complex, and therefore, knowledge on the part of the faculty member is necessary for the proper use of search algorithms, classification of hypertexts and other documents accessible and available on the Web.…”

“…Outra faceta do BD está relacionada com a necessidade de lidar com dados imprecisos e incertos, sendo a Veracidade associada com a qualidade e ou confiabilidade dos dados. O Valor pode ser tanto associado a dados que gerem resultados (dados valiosos), isto é, que geram informações relevantes e para isso precisam ter qualidade, como também está associado ao retorno dos investimentos que foram locados em todos os outros 'Vs' a fim de atribuir sentido ao volume de dados de maneira estratégica (FAGUNDES;MACEDO;FREUND, 2018). A informação há tempos é considerada valiosa, porém os dados eram vistos como subproduto de determinadas operações, atualmente se observa que o valor da grande maioria dos dados passou do uso secundário para o uso potencial, sugerindo que seu valor é muito maior do que o valor imediato.…”

“…Technological advances have helped generate a large quantity of data, becoming a complex task when using current technologies, such as blockchain, cloud computing, fog computing, and artificial intelligence, among others. In this way, some research addresses the technological aspects mentioned in the perspectives of computer science and information sciences [ 6 , 7 , 8 , 9 , 10 ]. In this sense, the need to manage large volumes of data in HISs meets the use of computational strategies that address the historical processing of this data (i.e., provenance management) [ 11 , 12 ].…”
