Research on Diagnostic Information of Smart Medical Care Based on Big Data

Algorithm 1

The implementation process of the Mapper algorithm.

(a)	Read electronic medical record file, If file <> ∅ & Not Eof (all files) then loop
	Read the string into the variable str;
(b)	If str = “age” then Key = age value (numeric);
Else continues to read backward;
End If
(c)	If str = “diagnostic result” then Value = disease name (string type);
Else continues to read backwards; End If
(d)	Write the generated (Key, Value) key-value pair to the intermediate result file;
