Descriptions:

Derivational variants - all 1 derivational step derivation pairs (dpair) that are in Lexicon and match with one of our SD-Rules are retrieved in this table.

7negation
  • N: negative
  • O: otherwise
8Type
  • P: prefix derivation
  • S: suffix derivation
  • Z: zero derivation
9Prefix
  • prefix: prefixD
  • None: otherwise

Algorithm:

  • Go through Lexicon to find raw zeroD, prefixD, and suffixD pairs
  • Go through filter algorithms
  • Integrated with expert tagging (derivations with 1 derivational step are tagged as valid)
  • Final validation
  • Combined validated zeroD, prefixD, and suffixD
  • Valid OrgD are evaluated and added in 2014+.
    • Must have EUIs (in Lexicon)
    • valid dPairs
    • If a dPair is not include in our SD-Rules, but in Lexicon can be added in here.
  • Please refer to derivations design documents for details
