RE: UNICODE character identification
What encoding is your data in? utf8? Single-byte encoding? Marc8? That information matters a lot to determine whether your idea would work. If it is in a single-byte encoding there is often no way to determine the script the character belongs to. Wouter Kool Metadata Specialist · OCLC B.V. Schipholweg 99 · P.O.

Re: UNICODE character identification
yes probably this is where i was also heading, but thought there was a more
clever way. Also, is there a good perl normaliser? I have not had any
experience with:
http://search.cpan.org/~sadahiro/Unicode-Normalize-1.18/Normalize.pm
For starters if i could spot only the odd letters between latin and greek
regex character classes, i would be more than happy

Apologies, I missed the subject line...
Then you might use the regex character classes. For instance $text =~
m/\p{Hiragana}/; matches any Japanese Hiragana character. I have not tested
it, but I suppose /[^\p{Latin}]/ would match any non-latin characters. So you
find the character class that most characters match and you look for the
exceptions. Would that help?

Hello friendly folks,
follows what i am trying to do, and i am looking for your help in order to
find the most clever way to achieve this:
We have records, that include typos like this: we have a word say Plato,
where the last o is inputted with the keyboard set to Greek language, so we
need something that would parse all metadata in a per character basis,
check against what is the script language that the majority of characters
the word belongs to have, and return the odd characters, the script they
belong, and the record identifier they were found in, so as to be able to
correct them
thank you in advance
Re: UNICODE character identification
looks good, though i guess it is a deprecated module,
thank you though for the info, will further investigate towards the machine
learning process, but i guess my use case is simpler: Check if a character
belongs to a certain set = language, and see if it is odd, based on the
language of the word
2015-02-10 17:17 GMT+02:00 Kool,Wouter wouter.k...@oclc.org:
You might also take a machine learning approach, like Naïve Bayesian
Classification. For instance
http://search.cpan.org/~kwilliams/Algorithm-NaiveBayes-0.04/lib/Algorithm/NaiveBayes.pm.
You build test sets from records in various scripts and use the classifier
to find hybrid cases. I have quite satisfactory results with this approach
in a slightly different use case.
