[omega] Two-level morphology

[Yannis Haralambous]

I found that there are similarities between our notion of textemes (or 
@@@emes as Chris calls them) and two-level morphology 
<http://www.ling.helsinki.fi/~koskenni/esslli-2001-karttunen/> as 
defined by Kimmo Koskenniemi in the eighties. The two levels are: the 
lexical one and the "surface" one.

Here is an example (taken from Jean Véronis' course):

lexical: c h a t + e
surface: c h a t t e

where the + means "morpheme boundary", this is similar to a texteme 
with a special character and with "glyph" t

lexical: c h e v a l + s
surface: c h e v a u # x

where the # means "empty character", but in our case it sounds more 
like a texteme with a special character
and without "glyph"

Keeping the same analogy, OTPs play the role of transducers.

Is this a mere similarity or is there something more profound behind it?
Anyone proficient in this field?
