Instance Attribute Details

#corpus ⇒ Object (readonly)

Pass in a text, and optionally an existing Markov chain to add data to. In many cases, you may be building a chain using a set of smaller texts instead of one large texts (dialog, for instance, or Twitter archives), and so may call this class repeatedly for elements of the parent corpus.
