Thank you for your open source work. Could you please explain the parsing method : left2right, deep first, shallow first, inside out in code of , looking forward to your reply

These are the options for selecting the order of the children of a head word in the stack-pointer parser. The stack-pointer parser, at each step, selects a child for the current head word. But it raises a question for head words that have multiple children: what is the order of these children?

For left2right, these children are ordered from left-to-right, i.e. selecting the left-most word first. For inside-out, the child that closest to the head word is selected first.

In practice, inside-out works best. So we set inside-out as our default option.
