> 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.
