> Dumping term vectors with a dictionary using:
> {{mahout vectordump -s vector-output/chunk-0 -dt sequencefile -d dictionary-output}}
> gives me output like the following with no values, just the indexes expanded into their
dictionary entries:
> {code}
> Name: 0001-11055 elts: {513:discard, 7199:empty,...
> {code}
> While dumping the same vector without a dictionary using
> {{mahout vectordump -s vector-output/chunk-0}}
> gives me output that includes indexes and values:
> {code}
> Name: 0001-11055 elts: {513:1.0, 7199:1.0...
> {code}
> Would it make sense for the dictionary based output to include values as well? Anyone
opposed to modifying VectorHelper.vectorToString(Vector, String[]) to do so?
