Natural Language Processing (NLP) Service


We have set up the CRIS Natural Language Processing (NLP) Service to facilitate the extraction of anonymised information from the free text of the clinical record at the South London and Maudsley NHS Trust.

Research using data from electronic health records (EHRs) is rapidly increasing and most of the valuable information is sought in the free text. However, manually reviewing the free text is very time consuming. To overcome the burden of manual work and extract the information needed, NLP methods are utilised and in high demand throughout the research world.

The document published and regularly updated here contains the details and performance of over 60 NLP applications relating to the automatic extraction of mental health data from the EHR that we have developed and currently routinely deploy through our NLP service.
