getContext

String[] getContext(int i,
                    String[] toks,
                    String[] tags,
                    String[] preds)

Returns the contexts for chunking of the specified index.

i - The index of the token in the specified toks array for which the context should be constructed.

toks - The tokens of the sentence. The toString methods of these objects should return the token text.

tags - The POS tags for the the specified tokens.

preds - The previous decisions made in the taging of this sequence. Only indices less than i will be examined.

Returns:

An array of predictive contexts on which a model basis its decisions.
