NodeNotFound exception during splitting

[kastein]

Recipe: cobb_salad_8 Instruction 3: "Note : A tip to make this a very easy meal is to purchase the hard boiled eggs , pre - cooked bacon , blue cheese crumbles and pre - cooked chicken ."

Problem:

1. "pre", "-" and "cooked" are tagged as separate actions (see below)
2. "pre" is represented with "before" in the AMR -> gets removed during the splitting algorithm -> action nodes is lost and path from that node to the other action nodes cannot be computed anymore

Possible Solutions:

• Check if 'before' or 'after' is aligned to an action before removing; if yes, don't remove but how to continue with splitting?
• Handle as parsing/tagging error and do not separate AMR because there should never be a 'before' or 'after' action-aligned node?

Decision for now: do not split AMR at all if this error occurs
