Thomas Neidhart commented on CODEC-187:
---------------------------------------
This has to be further analysed, but I doubt that the algorithm / code has
changed at all. The Beider Morse phonetic encoder is a generic rule-based
replacement algorithm with domain-specific rules.
Having said this, I could imagine that we add different versions of the rules
and allow the user to create instances of the BeiderMorseEncoder using
different rulesets. Just keep in mind that the current ruleset is approx. 548kB
uncompressed and ~115kB compressed, which means if we add multiple versions
this would further increase the size of the jar file.
Furthermore, if updates to the rules just result in more tokens to be returned,
no re-indexing would be necessary imho (it might create better results though).

> Key: CODEC-187
> URL: https://issues.apache.org/jira/browse/CODEC-187
> Project: Commons Codec
> Issue Type: Bug
> Affects Versions: 1.9
> Reporter: michael tobias
> Priority: Minor
> Fix For: 1.10
>
> Attachments: CODEC-187.patch
>
>
> 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?
