This web page, based on Pinda tool, presents additional visualizations for a systematic mapping study about text mining and semantics, and the full list of papers can be downloaded here. There are two visualization sets defined by the selected dataset, which can be accessed in the top right menu. Title + Abstract dataset refers to visualizations of document contents (title and abstract). SM Results dataset refers to visualizations of results (information extracted) of the systematic mapping study.
This tool provide an hierarchical visualization of the textual data, using K-means algorithm to group the results. It allows the analysis of data (title+abstract of selected studies or information extracted of accepted studies) through multiple Visualization techniques (Thumbnail, Snippets, Directories, Scatterplot, Treemap and Sunburst), coordinating the user interactions for a better understanding of existing relationships.
The labels of Sunburst visualization can be hide by the Labels button, located on the bottom right region. Analogously, category information can be highlighted on the top left buttons in the Scatterplot area.
