A Natural Language Processing (NLP) Approach to Automate Patients’ Testimonials Analysis


Patient's testimonials provide valuable insights to define and characterize Quality of life and patient's perspective of their disease, whether it is about their symptoms, or their advice to others, or what makes them suffer. Extracting information from these stories is therefore relevant to improving care. However, traditional NLP methods of topic modelling are not adapted to these generally short health-specific texts, in majority because they are based on the co-occurrence of words. We propose here a short introduction of the state of the art of these methods and a solution adapted to the extraction of relevant information from this type of textual data.

Session Outline:

I: State of the art on Topic Modelling
II: Use cases in health textual data
III: Analytical pipeline demonstration

Background Knowledge:

Use of python and basic NLP
