[jira] Created: (MAHOUT-271) Make WikipediaDatasetCreatorMapper fuzzy category match respect word boundaries

Make WikipediaDatasetCreatorMapper fuzzy category match respect word boundaries
-------------------------------------------------------------------------------

                 Key: MAHOUT-271
                 URL: https://issues.apache.org/jira/browse/MAHOUT-271
             Project: Mahout
          Issue Type: Improvement
          Components: Classification
    Affects Versions: 0.2
            Reporter: Olivier Grisel
            Assignee: Olivier Grisel
            Priority: Trivial
             Fix For: 0.3


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.
