InfraNodus is a nonlinear reading tool.
InfraNodus is an open-source tool that can be used to better understand, research, and generate insight about any text or idea. It visualizes a text as a network to show you the most relevant topics, their relations, and the structural gaps between them to help you generate new ideas.
Using the interactive graph you can quickly understand what the text is about and get a different perspective on it. If you click on any words in the graph, you will quickly get to the parts of the text where those terms tend to appear.
InfraNodus is used by hundreds of researchers worldwide to perform and teach text-related studies, to analyze customer feedback data in marketing, to improve search engine optimization, to perform text mining operations (including in-built LDA analysis), to make sense of bits and pieces of disjointed textual data, and to create and share mindmaps and network graphs. It supports English, French, German, Russian, Spanish, Portugese and Swedish languages, with Chinese and Japanese to be implemented soon.
