Grant Ingersoll commented on MAHOUT-126: ---------------------------------------- Agreed about the weirdness on the default norms. Yeah, patch would be great. > Prepare document vectors from the text > -------------------------------------- > > Key: MAHOUT-126 > URL: https://issues.apache.org/jira/browse/MAHOUT-126 > Project: Mahout > Issue Type: New Feature > Affects Versions: 0.2 > Reporter: Shashikant Kore > Assignee: Grant Ingersoll > Fix For: 0.2 > > Attachments: mahout-126-benson.patch, MAHOUT-126.patch, > MAHOUT-126.patch, MAHOUT-126.patch, MAHOUT-126.patch > > > 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.
