```
String[] getContext(int i,
                    String[] toks,

                    String[] preds)
```
    Returns the contexts for chunking of the specified index.
    
    Parameters:
    
    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:
