INFLECTED

INFLECTED is a top-level attribute with an AVM of "flags" as its value. Flags model the co-occurrence restrictions between lexical types and lexical rule types, and draw their values from the luk hierarchy.

Regression testing

The following patterns are, or should be, implemented to ensure the morphotactic system is working properly:

Test	Details	Implemented
morph-optional-pc	One PC, takes one LT as input, optional	No
morph-oblig-pc	One PC, takes one LT as input, obligatory	No
morph-optional-pc-lt1-requires	One PC, takes two LTs as input, one LT requires PC	No
morph-2nd-pc-req-lrt1	Two sequential PCs, two LTs, oblig PC1 takes both as input, opt PC2 requires LT1	No
morph-2nd-pc-fbd-lrt1	Two sequential PCs, two LTs, oblig PC1 takes both as input, opt PC2 forbids LT1	No
morph-implicit-disj	Two non-sequential PCs, one LT requires both separately, disjunctive flag created	No
morph-explicit-disj	Two non-sequential PCs, one LT disjunctively requires both, disjunctive flag created	No

Note that some tests may be collapsed.

History

(pre-O'Hara description?)

O'Hara added TRACK variables for co-occurrence restrictions and planning of lexeme-to-lexeme and lexeme-to-word (sometimes word-to-lexeme) rules to handle obligatory rules. [http://www.delph-in.net/matrix/kohara-thesis.pdf O'Hara 2008]

Goodman merged TRACK into INFLECTED so co-occurrence constraints directly affect lexical integrity (ability to use lexemes with syntactic (phrasal) rules. [http://makino.linguist.univ-paris-diderot.fr/files/hpsg2010/file/abstracts/MFG/goodman-bender-mfg.pdf Goodman and Bender 2010]
