[arabic-vip] WHOIS related query

[Dr.Sarmad Hussain]

Dear Manal and All,

Theoretically, if we have n letters in a label, and the letters have m
variants each, then the total possibilities are m^n.  So for a 10 letter
label, with say three variants per letter (e.g. kaf), we have 3^10 variants
i.e. about 59,000.  Now add optional mark on each letter (two possibilities:
with mark without mark per letter; assuming these are considered
equivalent); for a single sequence of n letters, there 2^n possibilities,
i.e. 1,000 approx.  Thus total possibilities with variants and marks would
be 59K*1K, which gives a order of 100's of millions (if my mathematics is
correct).

So Raed's estimates are without aerab/diacritical marks, just on letters.

However, practically speaking, "real" words (if there is such a thing for a
label definition) would be fewer (this is most of the cases).

Having said that, we must plan for boundary cases, not just "real" cases as
the theoretical limits must also be catered for.

Two possible solutions:

1. contain the variants by putting an upper limit
2. contain the language table to avoid generation of too many variants
(harder to do, without significantly limiting linguistic expression)

If we choose option 1, then we need terminology and mechanisms to articulate
and enable this.

I am not sure what is the best option at this time.

regards,
Sarmad
