Description
This specialized radiology pipeline can;
-
extract radiology related entities,
-
assign assertion status to the extracted entities,
-
establish relations between the extracted entities from the clinical documents.
In this pipeline, five NER, one assertion and one relation extraction model were used to achive those tasks.
-
Clinical Entity Labels:
Imaging_Test,Imaging_Technique,ImagingFindings,OtherFindings,BodyPart,Direction,Test,Symptom,Disease_Syndrome_Disorder,Medical_Device,Procedure,Measurements,Units,Gender,Metastasis,Invasion,Route,Treatment,Drug,Form,Frequency,Dosage,Date,Test_Result,Medical_Device -
Assertion Status Labels:
Confirmed,Suspected,Negative -
