<p><tt>Dear Samia, <br>
</tt></p>
<p><tt>my paper on reduplication (including infixation) just came
out a few months ago in morphology. </tt>As for infixation, you
will see that it is a matter of distance. If this is about root
and pattern morphology, you may consider some sort of
autosegmental representation. Look at Bird and Klein 1994 for a
theoretical approach, and at my Hausa tone paper (Journal of
Language Modelling 2015) for how these things can be done with LKB
and friends. Are you using vocalised or unvocalised Arabic? If you
translate some of the input into feature structures, you may have
an easier time. If you operate with autosegmental structures you
will certainly reduce distance. As far as I remember root have
between 3 and 4 consonants, so the distance from the edge is
maximally 2. For autosegmental approaches to work, you'd need the
preprocessing machinery offered by pet and ace. <br>
</p>
<p>Why don't you post some example of what exactly you have in mind.
<br>

<p>Cheers, <br>

Thanks for your message. As far as I'm aware, the
morphology module in the LKB is relatively limited and
does not directly give you a way to define infixes.
However, I think it should be possible to get this kind of
behaviour -- for example, Berthold Crysmann has used
string unification to implement reduplication for a
grammar of Hausa. I wouldn't be able to explain the
details of this, but perhaps one of the other developers
on this list will be able to give you an answer in the
next few days.<br>

<div>I'm Samia Ben Ismail. I'm from Tunisia. I'm a
phd student. I use LKB to generate an Arabic
linguistic resources. Can you tell me please it is
possible to add new operations ( replacement, add
and delete a letter) to the infix (middle) of the
word. If, it is possible, tell me please, how I
can obtain the open source of LKB?</div>
