Which algorithm (and language) can do this?

Hi everyone,<br><br>I'm trying to develop an AI (mostly using Python, but I'm ready to change if necessary) that can detect when a story is inspired from another.<br><br>Here's an example:<br><br>Person A: "As the wind began to blow, the last leaf of the tree fell to the ground. You'll be the next, said the tree."<br><br>Person B: "As the wind began to blow, the last leaf of the tree fell to the ground. You'll be the next, said the tree. 'No! I'm not! You'll be the next!' shouted the leaf. "<br><br><br>In this example, the algorithm should say that the story produced by person B was most likely inspired by the story produced by person A.<br><br>I looked up a lot and I don't find anything that can do that (it's mostly plagiarism checkers).<br><br>Do you have any ideas or (even) tips?
