[jira] Updated: (MAHOUT-61) Text problem matrix builder

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

Karl Wettin updated MAHOUT-61:
------------------------------

       Assignee: Karl Wettin
    Description: 
A set of classes that builds matrices from text.

Currently the API consists of TokenMatrixBuilder and TokenInstanceBuilder. Should be thread safe.

PostReader imports 20news-bydate. This takes several GB heap. It would be nice to bounce the data via JDBM or perhaps using the PersistentHashMap in MAHOUT-19.
        Summary: Text problem matrix builder   (was: Text classification matrix )

Oups, I hit enter a bit too early
