NLP.GenI.Morphology
Description
This module handles mostly everything to do with morphology in Geni.
There are two basic tasks: morphological input and output.
GenI farms out morphology to whatever third party program you
specify on the command line. Note that a simple and stupid
`sillymorph' realiser is provided either in the GenI repository
or on hackage.

Morphological predicates
readMorph :: [(Text, [AvPair GeniVal])] -> MorphInputFn
Converts information from a morphological information file into GenI's internal format.
stripMorphSem :: MorphInputFn -> Sem -> Sem
Filters away from an input semantics any literals whose realisation is
strictly morphological. The first argument tells us helps identify the
morphological literals -- it associates literals with morphological stuff;
if it returns Nothing, then it is non-morphological
attachMorph :: MorphInputFn -> Sem -> [TagElem] -> [TagElem]
attachMorph morphfn sem cands does the bulk of the morphological
input processing. We use morphfn to determine which literals in
sem contain morphological information and what information they contain.
Then we attach this morphological information to the relevant trees in
cand. A tree is considered relevant w.r.t to a morphological
literal if its semantics contains at least one literal whose first index
is the same as the first index of the morphological literal.
setMorphAnchor :: GNode GeniVal -> Tree (GNode GeniVal) -> Tree (GNode GeniVal)
setMorphAnchor n t replaces the anchor node of a tree with n
We assume the tree has exactly one anchor node. If it has none, this explodes; if it has more than one, they all get replaced.
Morphological realisation
inflectSentencesUsingCmd :: String -> [LemmaPlusSentence] -> IO [(LemmaPlusSentence, MorphOutput)]
Converts a list of uninflected sentences into inflected ones by calling
sansMorph :: LemmaPlusSentence -> MorphOutput
Extracts the lemmas from a list of uninflected sentences. This is used when the morphological generator is unavailable, doesn't work, etc.
