Reference-Based Analysis of Coherence and Diversity in Open-Ended Text Generation

The paper introduces a reference-based framework to analyze coherence and diversity in open-ended text generation. It evaluates these properties by aligning them with human trajectories, comparing them to human continuations, and estimating their likelihood under a human reference distribution. Experiments show that diversity alignment and mean-based comparisons correlate with human quality ratings, while reference likelihood also associates positively, though results vary by configuration.
