PrAVA: Preprocessing profiling approach for visual analytics

Abstract: To accommodate the demands of a data-driven society, we have expanded our ability to collect and store data, develop sophisticated algorithms, and generate elaborated visual representations of the data analysis process outcomes. However, data preprocessing, as the activity of transforming the raw data into an appropriate format for subsequent analysis, is still a challenging part of this process. Although we can find studies that address the use of visualization techniques to support the activities in the scop… Show more

“…The responses of the interviewees led us to a list of ten insights for new visualization solutions [1]. After that, we developed a conceptual VA process that includes preprocessing profiling as a new phase, and we indicate a list of research opportunities in the scope of preprocessing combined with visualization and VA [4]. This work was developed with the collaboration of Fernando Paulovich 2 from Dalhousie University.…”

“…Although we continue researching the initial topic of social media data visualization, novel research topics were added through these years. Recently, we have dedicated efforts to verify how visualization can help in data preprocessing activities [1]- [4], a task that demands a lot of time for data analysts [5]. A result of this research can be seen in a paper we recently published with a conceptual process that includes preprocessing profiling as a new phase in the Visual Analytics (VA) process [4].…”
