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

    [ https://issues.apache.org/jira/browse/DATAFU-61?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16161118#comment-16161118 ] 

Eyal Allweil commented on DATAFU-61:
------------------------------------

Came back to this today and tried a little experiment - I verified (calculating manually) that the Russell's code produces the same results as the "augmented TF" IDF flavor for the sample I took from the wikipedia page. Is that good enough for us?
