Ranked Preference Notation

Example of Listwise Ranking in RLHF

A language model generates two different summaries for a given article: Summary 1 and Summary 2. A human evaluator is tasked with reviewing them and determines that Summary 1 is more coherent and factually accurate than Summary 2. How would this specific judgment be formally expressed using standard preference notation?

A human annotator provides the following judgments for four text completions (C1, C2, C3, C4) generated in response to a single prompt: C1 ≻ C4, C4 ≻ C2, and C2 ≻ C3. Based on this information, arrange the completions in order from most preferred to least preferred.
