Dear Ada,
I am afraid your suggestion is something that the Ontolex-lemon model
does not support (which is important since the question was specifically
about that model for representing lexicographic information, not just
general approaches for dealing with non-concatenative morphology). It is
very similar though to the underlying current approach that we use in
the model (that Christian described in his response).
While developing this model as a community effort we try really hard to
avoid eurocentric views, but since the whole premise of OntoLex is to
model data, we rely on existing resources, not inventing them from
scratch. So the model can represent word lists as well as computational
lexicons or many other types of lexicographic data existing out there.
Best regards,
Max

Dear Hugh
An alternative would be to use dictionaries (as in, "{ }" in python)
to group characters belonging to the consonant and vowel groups (or at
least one of them) and then examine accordingly. This should render
more scientific insights on sequences than relying on bigger spans of
hard-coded information (on "word"/"morph(eme)"-level), esp. when one
calculates the transition probabilities and interpret accordingly.
(Remember the whitespaces (if any) and use continuous texts/data (i.e.
not just colonial data e.g. "word lists")!) What is the purpose,
though, of your task that is supposed to be related to "morphology"?

What I forgot to state is the most elementary aspect: an
ontolex:LexicalEntry can be associated with a (nonconcatenative)
morph:Morph or a (nonconcatenative) morph:Rule/morph:Replacement
in the following ways:
- for word formation: the lexical entry (e.g., a lexinfo:Root)
from which one or more derived forms can be encoded as the
vartrans:source of a morph:WordFormationRelation and an associated
morph:WordFormationRule
- for inflection: the lexical entry can have an
ontolex:morphologicalPattern relation pointing to a
morph:Paradigm. Such paradigms are the morph:paradigm of
morph:InflectionRules.
Both morph:InflectionRule and morph:WordFormationRule are
morph:Rules and can thus be connected to a non-concatenative
morpheme (or replacement) as described in the other email.
Our current real-world examples for noncontenative morphology are
from word formation, only. I guess your usecase is more in the
inflection area (because for word formation, it would be practical
to give a lexical sense, and then you'd need a LexicalEntry
anyway), but the noncontenative part of the specification (by
means of regular expressions and capturing groups in
morph:Replacement) is identical in both use scenarios.

Dear Hugh,
this has been addressed in the context of the emerging
OntoLex-Morph vocabulary
(https://www.w3.org/community/ontolex/wiki/Morphology,
https://github.com/ontolex/morph; most recent diagram under
https://github.com/ontolex/morph/blob/master/doc/diagrams/Readme.md).
Here, a morph:Morph object (a lexical entry of a lexical
resource for morphemes, depending on the type of resource,
this can be a morpheme or an allomorph of a morpheme), can be
the object of a morph:involves property that connects it with
a morph:Rule. This morph:Rule can have one or more
morph:replacement properties. The morph:Replacement objects
that this points to use regular expressions to formalize
source and target strings of the rule associated with that
particular morph(eme). These use Perl/Java/SPARQL-style regex
syntax, which includes the support for capturing groups.
Note that this formalizes the form side of morphemes only, not
the meaning side. However, a morph:Rule can also have a
morph:grammaticalMeaning property to which such information
can be added. Last week, Max Ionov and Mike Rosner have
described the application (and an extension) of this mechanism
for Maltese in a recent LDK paper: Beyond Concatenative
Morphology: Applying OntoLex-Morph to Maltese /Maxim Ionov,
Mike Rosner/. (Not online, yet.) We were also looking into
other Semitic languages (and related phenomena such as Umlaut
in German or vowel harmony in Turkic), but only on individual
examples. If anyone is interested in discussing this further,
please join the biweekly OntoLex-Morph calls ;)
The OntoLex-Morph vocabulary is relatively advanced, and we
are in the process of freezing it in order to prepare its
publication. Finalization of the report is expected for
mid-next year.
Best,
Christian

Greetings,
Does anyone know of any descriptions or approaches to
using Ontolex/lemon with non-concatenative morphology? Is
the assumption that Cv1Cv2C shaped words will have their
own entries for each instance of changes for v1 and v2? If
this is the case, then this radically increases the number
of items in a dictionary when compared with languages with
affix type morphology.
Any pointers appreciated,
Kind regards,
Hugh
