The SPECIALIST Lexicon

Derivations (DM.DB)

Descriptions:

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

Fields:

FieldNameNotes
1BASBase form
2SCASyntactic category (name)
3EUIEui of base
4BASBase form of derivational variant
5SCASyntactic category (name)
6EUIEui of derivation
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
