Modeling the Dashboard Provenance
Organizations of all kinds, whether public or private, profit-driven or
non-profit, and across various industries and sectors, rely on dashboards for
effective data visualization. However, the reliability and efficacy of these
dashboards rely on the quality of the visual and data they present. Studies
show that less than a quarter of dashboards provide information about their
sources, which is just one of the expected metadata when provenance is
seriously considered. Provenance is a record that describes people,
organizations, entities, and activities that had a role in the production,
influence, or delivery of a piece of data or an object. This paper aims to
provide a provenance representation model, that entitles standardization,
modeling, generation, capture, and visualization, specifically designed for
dashboards and its visual and data components. The proposed model will offer a
comprehensive set of essential provenance metadata that enables users to
evaluate the quality, consistency, and reliability of the information presented
on dashboards. This will allow a clear and precise understanding of the context
in which a specific dashboard was developed, ultimately leading to better
decision-making.Comment: 8 pages, 4 figures, one table, to be published in VIS 2023 (Vis +

Contributions of remote collaborative sketching to the design of infovis in public health
This paper presents contributions from using remote collaborative sketching to infovis for public health. The results come from an interdisciplinary study that involved designers, health researchers, public managers and computer scientists in the production of sketches generating alternatives for creating valuable graphics and dashboards. One of the creative stages was the remote collaborative workshops in which design alternatives were proposed based on sketches. The sketches were developed with the support of videoconferencing meetings, virtual boards, and graphic tablets. From this practice, we were able to include as contributions to the creative process in infovis: remote collaboration expansion; agile and iterative cycles improvement; interface design preview; data modeling supporting; addressing graphic literacy issues; creative process documentation; participant experience improvement; and additional information incorporation
O uso de mapas auto-organizáveis como ferramenta de análise exploratória em testes cognitivos destinados a medir o desempenho escolar
Apesar da melhora nos Ãndices de escolarização apontada por indicadores internacionais tais
como o PISA 2012/2015 - Programme for International Student Assessment, a qualidade da
educação no Brasil continua muito ruim, necessitando de melhorias em praticamente todos
os aspectos avaliados pela Organisation for Economic Co-operation and Development -
OECD, que organiza o PISA, tais como o desempenho na leitura e no ensino da matemática.
Este estudo tem como objetivo contribuir com técnicas que possam aperfeiçoar a análise
dos dados educacionais e propõe o uso de mapas auto-organizáveis (SOM) como ferramenta
para a análise exploratória de dados no apoio a descobertas e diagnósticos relativos a
performance escolar, focando na análise de testes voltados para medir o desenvolvimento
das habilidades cognitivas em estudantes. Espera-se que essas técnicas de analise possam
auxiliar os pesquisadores da área educacional na elaboração de melhores diagnósticos
relativos ao desenvolvimento cognitivo dos estudantes e auxiliar no processo de validação
e normalização dos testes cognitivos, provendo, desta forma, técnicas para visualização
dos dados, identificação de padrões, identificação de outliers, detecção de agrupamentos e
busca por informações ocultas nos dados.Despite the improvement in schooling rates pointed by international indicators such as PISA
2012/2015 - Program for International Student Assessment, the education quality in Brazil
continues to be very poor, necessitating improvements in practically all aspects assessed

This study aims to contribute with techniques that can improve the analysis of educational
data and proposes the use of self-organizing maps (SOM) as a tool for exploratory data
analysis to support discoveries and diagnoses related to school performance, focusing
on the analysis of tests developed to measure the development of cognitive abilities in
students. It is hoped that these techniques of analysis can help educational researchers
in the preparation of better diagnoses related to student’s cognitive development and to
assist in the validation process and normalization of the cognitive tests, thus providing
techniques for data visualization, patterns and outliers detection, cluster analysis and
searching at hidden information in the data.Coordenação de Aperfeiçoamento de Pessoal de NÃvel Superio
