Sean Owen updated MAHOUT-271:
-----------------------------
Status: Resolved (was: Patch Available)
Resolution: Fixed
Resolved with a version of your patch Joe. I thought it might be wasteful to
compile the regexes in every map() so pre-computed them in setup(). (And
rearranged the code somewhat.)
> Make WikipediaDatasetCreatorMapper fuzzy category match respect word
> boundaries

> WikipediaDatasetCreatorDriver is useful to create categorisation corpora out
> of wikipedia, however the category match just do a String#contains check
> which can catch a lot of unrelated categories.
> Checking the word boundaries with a regexp such as String.format("\\b%s\\b",
> theCategoryNameIAmLookingFor); should fix the issue.
