UMLS-Core: Performance

• Descriptions:
  • The synonym substitution could be very expensive due to the huge number of permutations on all possible synonym substitutions. In practice, we only limited the synonym substitutions to one or two to increase the performance and precision rate. The algorithm needs to design accordingly to exclude any permutation exceeed the limit for the performance reason.

• Examples - Test Cases:
  • Input term:
    VA10052|Extracapsular Cataract Removal with Insertion of IOL Prosthesis (1-Stage), Complex, Requiring Devices or Techniques not Generally used in Routine Cataract Surgery or Performed on Patients in the Amblyogenic Developmental Stag
  • Synonym Norm:
    extracapsular cataract removal with insertion of iol prosthesis 1 stage complex requiring devices or techniques not generally used in routine cataract surgery or performed on patients in the amblyogenic developmental stage

  • Total permutations of synonym substitutions for CUI mapping:
    165,150,720= 2 x 14 x 2 x 4 x 6 x 2 x 2 x 2 x 2 x 5 x 2 x 2 x 2 x 6 x 2 x 2 x 8
    If each mapping take 0.1 sec., it will take 458.6311 hr. (19.10 days) for the mapping. This is too expensive!
