- Massive Text Data VisualizationPublication . Voltoline, Giovana; Pais, Sebastião Augusto Rodrigues FigueiredoThis thesis focuses on the development of a specialized solution for the visualization of textual data. With the increasing volume of unstructured text in various fields of research, there is a growing need for effective tools that help users analyze and visualize such data. The primary objective of this research is twofold: first, to investigate the needs and challenges faced by researchers working with text data, and second, to design and implement a practical solution that meets those needs. The initial phase involves an extensive review of the literature, aiming to understand the current landscape of text data visualization, categorize researcher objectives, and identify the processes they follow. This research informs the selection of visualization types and the most suitable Python libraries to implement them. The final product is made accessible as both a Python package and an open-source repository on GitHub, providing a flexible tool that addresses the key challenges in text data visualization. This thesis not only contributes a functional tool for researchers but also highlights the importance of targeted solutions in handling and visualizing unstructured textual data.
