InfraNodus is a text network analysis platform that can generate insight from any discourse: social media discourse, search results, corporate reports, news, spreadsheets, PDF documents. It is based on representing a text as a network graph with the most relevant topical clusters and the relations between them. Using the graph it is possible to identify the structural gaps in the knowledge: the areas with a high potential for new innovative ideas. It is also possible to use this approach to better understand the context of any sentiment.
