Evaluation notes

Workflow

The experiment is composed of the following steps (accordingly to the MapReduce schema):

  1. the map task,
    1. for each HL7 file saved on HDFS do:
      1. parse document in order to find out abnormal laboratory results - count them and next add into the context the following pair: Key=icd10 code, Value=the count of the abnormal results 
  2. the reduce task:
    1. for each icd10 code accumulate the count of the abnormal results
    2. produce the result pair Key=icd10 code, Value=the number of abnormal results
