  • The original derivations table in Lexical Tools was developed and used in C versions by linguists. It includes 4,559 derivation pairs come from five main sources.
  • In 2012 release, LSG reviewed these derivations tables and 75 synonyms and 11 mistakes were filtered out to results in 4473 pairs of derivations:
    • total unique data: 4473 records
    • remove 75 synonyms from etc.fct (etc.fct.org.synonyms)

    • In addition, 13 modifications (derivation.org.err.modify.txt) from the original derivations table
  • In 2013 release, these orgD pairs are excluded from SD-Facts due to lack of EUI information (which are needed in the new designed derivation DB table)
  • In 2014 release, LSG add verified orgD pairs in DB derivation table:
    • retrieve orgD pairs with valid EUIs in Lexicon.2014 (3,928)
    • identify above orgD pairs are already included DB derivation table
    • validate those orgD with EUIs that are not in DB derivation table
      • suffixD: 1609
      • prefixD: 1
      • zeroD: 0 (all 220 zerpD pairs are already in DB derivation table)
      • unknownD: 30
    • add lexical records of the rest of dPairs to Lexicon (for future releases)
