Looking at slide 39 (attached) I get the impression that I
should be able to do the following:
- turn a coding system (say, ICD-10) into a dictionary
by splitting the terms into single words
say, "diabetes mellitus -> "diabetes", "mellitus"
- define stop words like "left", "right", ...
say, "fracture left ulna" -> the "left" doesn't
matter as far as coding is concerned
- also turn that coding system into queries by splitting
the terms into single words, concatenating them
with "&", and setting the ICD 10 code as tag on them
say, "diabetes mellitus" -> "diabetes & mellitus [E11]"
- run an inverse FTS (FQS) against a user supplied string
thereby finding queries (= tags = ICD10 codes) likely
relevant to the input
say, to_tsvector("patient was suspected to suffer from diabetes mellitus")
-> tag = E11
Possible, not possible, insane, unintended use ?
Thanks,
Karsten
