PureDocBench - Digital Degraded - Text Edit Distance: leaderboard
Metric: Text normalized edit distance (%): edit distance between the predicted and reference text divided by the longer length, times 100, on the digitally degraded track (the same pages under ten simulated scene templates such as aging, binding, photocopying, compression, lighting and geometric artifacts) of 1,475 source pages in 10 domains and 66 subcategories, rendered from LLM-written HTML/CSS with source-linked annotations for text, formulas, tables and reading order; lower is better. Source: arxiv.org. Saturation forecast: Not forecast. 58 models tracked.
