[jira] [Updated] (DATAFU-61) Add TF-IDF Macro to DataFu

     [ https://issues.apache.org/jira/browse/DATAFU-61?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eyal Allweil updated DATAFU-61:
-------------------------------
    Attachment: DATAFU-61-2.patch

Now that macros are supported (and can be tested), I updated this patch. Unfortunately, I couldn't find the sample data, so I just pulled the sample sentences from the Wikipedia page for TF-IDF, and I didn't verify that the results are OK. [~russell.jurney] - want to donate a test case and expected results?
