Flow Specific Option - Derivation Restriction

  • Description:

    This option is used to filter derivations generated by facts and rules from the derivational morphology flows. This option is used to control the variants generated using the derivation modules. Its argument can be 1, 2, or 3.

    • 1: restricts the outputs to those variants which are known to the lexicon (facts only). This is the default.
    • 2: restricts the outputs to those variants which are known to the lexicon, unless none of the variants are found in the lexicon, in which case the rule generated list is returned (facts or rules). In other words, the result will be the same as option 1 if its derivations are in facts.
    • 3: No restriction on the outputs of the morphology. Both facts and rules generated variants are displayed (facts and rules).


  • Features:
    1. Restrict the output for derivation flows.
