mallet.doc.topics(topic.model, normalized, smoothed)

Arguments

The model returned by MalletLDA

normalized

If true, normalize the rows so that each document sums to one. If false, values will be integers (possibly plus the smoothing constant) representing the actual number of words of each topic in the documents.
