Make Wikipedia example set maker easier to mod
----------------------------------------------
Key: MAHOUT-895
URL: https://issues.apache.org/jira/browse/MAHOUT-895
Project: Mahout
Issue Type: Bug
Components: Classification, Examples
Affects Versions: 0.6
Reporter: tom pierce
Priority: Minor
The WikipediaDatasetCreator uses 2 mechanisms to scrape out the text of
articles; first an XmlInputFormat is used with the "text" tags as start/end
markers (which demarcate the article content), then the content inside the text
tags is pattern matched out in the Mapper.
This means a newcomer must discover both pruning steps before modifying this
program to create a dataset including other fields from the article.
I am attaching a patch which mods the Driver to split on entire articles and
changes the mapper to accommodate the extra input without allowing spurious new
category matches outside the text element.
