Hi Grant, You are probably right. What I wanted is to use my mahout setup to extract topics from a single document. So, maybe in popular terms I am trying to do topic extraction via document clustering. Does it make sense to try to split a doc into sub docs so that I leverage the clustering algorithm and thus find topic which appear key ones for the document?
