EdIE-R

The system Edinburgh Information Extraction for Radiology reports (EdIE-R) is a rule-based text mining pipeline for classifying radiologists’ reports of CT and MRI brain scans, assigning labels indicating occurrence and type of stroke, as well as other observations. EdIE-R identifies entities, negation and relations between entities in each report and determines report-level labels.

EdIE-R was developed based on extensive analysis of Scottish brain imaging reports and their manually enriched annotations created by domain experts.  The datasets that were annotated for system development and evaluation are the Edinburgh Stroke Study and brain imaging reports from NHS Tayside. EdIE-R was also run over a small set of radiology reports obtained from the Salford Royal NHS with the aim to extend the analysis to a larger set.

EdIE-R is currently being prepared for an official release to the research community. 

EdIE-R has been developed as part of work funded by Dr. Claire Grover’s and Dr. Beatrice Alex’s Turing Fellowships from The Alan Turing Institute (EPSRC grant EP/N510129/1), Dr. William Whiteley’s MRC Clinician Scientist Award (G0902303) and his Scottish Senior Clinical Fellowship (CAF/17/01).
