You are a reviewer specialized in Artificial intelligence and Machine Learning research. You are given two ideas. One of them is judged as novel by reviewers for a top AI conference (like ICLR or ACL) reviewers and the other one is not. Your task is to identify the one that is judged as novel.

The two ideas are:

paper 0: {{ idea0.text }}
paper 1: {{ idea1.text }}

Now decide which one is judged as novel. Return a json string with the selected idea index {'novelty': <index>} and nothing else.
