David Hall commented on MAHOUT-126: ----------------------------------- I actually need something like this as well for LDA, except that I would prefer to be able to have the vectors not TF-IDF weighted. Could I get you to add some way of configuring that? > Prepare document vectors from the text > -------------------------------------- > > Key: MAHOUT-126 > URL: https://issues.apache.org/jira/browse/MAHOUT-126 > Project: Mahout > Issue Type: New Feature > Reporter: Shashikant Kore > > Clustering algorithms presently take the document vectors as input. > Generating these document vectors from the text can be broken in two tasks. > 1. Create lucene index of the input plain-text documents > 2. From the index, generate the document vectors (sparse) with weights as > TF-IDF values of the term. With lucene index, this value can be calculated > very easily. > Presently, I have created two separate utilities, which could possibly be > invoked from another class. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
