Problem 2: Recognize the location, action and operand information

Each amendment essentially describes a change to the original text. For the next problems, it is required for the system to understand the nature of the change. Essentially, it needs a model of each change.

The model requires:

  1. Location information; Where does the change need to be made in the original text.

  2. Action information; How does the original text need to be modified.

  3. Operand information; Depending on the action information.

This is essentially an information extraction problem.
