michael tobias commented on CODEC-187:
--------------------------------------

As I think I said previously I suspect the most used settings for BMPM are 
GENERIC, APPROX and auto-language.  I am therefore concentrating on testing 
that.

Another small bug found.

The name Bendzin should produce tokens of 
binzn bindzn vindzn bintsn vintsn 

but is missing the final one (vintsn):
bindzn bintsn binzn vindzn

Can this be investigated?

> I believe the Beider Morse Phonetic Matching algorithm was added in Commons 
> Codec 1.6
> The BMPM algorithm is an EVOLVING algorithm that is currently on version 3.02 
> though it had been static since version 3.01 dated 19 Dec 2011 (it was first 
> available as opensource as version 1.00 on 6 May 2009).
> I can see nothing in the Commons Codec Docs to say which version of BMPM was 
> implemented so I am not sure if the problem with the algorithm as coded in 
> the Codec is simply an old version or whether there are more basic problems 
> with the implementation.
> How do I determine the version of the algorithm that was implemented in the 
> Commons Codec?
> How do we ensure that the algorithm is updated if/when the BMPM algorithm 
> changes?
> How do we ensure that the algorithm as coded in the Commons Codec is accurate 
> and working as expected?
