CasualTagger is a simple GUI front end of Yoichiro Hasebe's EngTagger, a Ruby port of Perl's Lingua::En::Tagger module.  What CasualTagger does is simply use EngTagger to add Part-of-Speech (POS) tags to English text from various files that include text data.  So you need to have EngTagger installed on your Mac.  For more information about EngTagger, check this site.

From version 0.6, CasualTagger supports rbtagger.  rbtagger is a Ruby tagger by Todd A. Fisher, which is based on Eric Brill's POS tagger.  It still has some issues, but it's mostly good and it's also nice to have alternative. 

Because CasualTagger depends on EngTagger and rbtagger, speed/accuracy/quality of tagging is as fast/good as EngTagger/rbtagger is.  At least I can say tagging process takes a lot of time if you process multiple files.

CasualTagger also has the Editor mode, which allows you to manually add tags to your text.  It has simple word count and kwic functions.

System Requirement: Any Mac with Mac OS X Leopard 10.5.5 or later + EngTagger (+ rbtagger)

The current version of CasualTagger is 0.6.

This is under development, so it still might have many bugs.  Please send any bug/use report.
