tethne.model.managers package

Module contents

This module provides manager classes for generating, visualizing, and analyzing models.

The following managers are presently available:

dtm.DTMModelManager	Generates a DTMModel from a Corpus using Gerrish’s C++ implementation.
mallet.MALLETModelManager	Generates a LDAModel from a Corpus using MALLET.
tap.TAPModelManager	Generates a time-sensitive set of TAPModels from a Corpus, a corpus model, and a coauthorship GraphCollection.

More managers will be added regularly.

class tethne.model.managers.ModelManager(outpath=None, temppath=None, **kwargs)
