Discursis

Discursis is communication analytics technology that allows a user to analyse text based communication data, in the form of conversations, web forums and training scenarios. 

It uses natural language processing algorithms to automatically process transcribed text to highlight participant interactions around specific topics and over the time-course of the conversation. 

Discursis can assist practitioners in understanding the structure, information content, and inter-speaker relationships that are present within input data. Discursis also provides quantitative measures of key metrics, such as topic introduction; topic consistency; and topic novelty.
