0.60 2003.04.05 - Added more locales by wrappering various stemming
implementations. Documented currently supported
list of locales.
0.50 2000.09.14 - Fixed major implementation error. Starting with
version 0.30 I forgot to include rulesets 2,3 and 4
for Porter's algorithm. The resulting stemming results
were very poor. Thanks go to <csyap@netfision.com>
for bringing the problem to my attention. Unfortunately,
the fix inherently generates *different*
stemming results than 0.30 and 0.40 did. If you
need identically broken output - use locale 'en-broken'.
0.40 2000.08.25 - Added stem caching support as an option. This
can provide a large speedup to the operation
of the stemmer. Caching is default turned off
to maximize compatibility with previous versions.
0.30 1999.06.24 - Replaced core of 'En' stemmers with code from
Jim Richardson <jimr@maths.usyd.edu.au>
Aliased 'en-us' and 'en-uk' to 'en'
Fixed 'SYNOPSIS' to correct return value
type for stemmed words (SYNOPIS error spotted
by <Arved_37@chebucto.ns.ca>)
0.20 1999.06.15 - Changed to '.pm' module, moved into Lingua:: namespace,
added OO interface, optionalized the export of routines
into the caller's namespace, added named parameter
initialization, stemming exceptions, autoloaded
locale support and isolated case flattening to
localized stemmers prevent i18n problems later.
Input and output text are assumed to be in UTF8
encoding (no operational impact right now, but
will be important when extending the module to
non-English).
