symplectic-inside-outside-atlas

A controlled ambiguity benchmark for exact CFG/PCFG parsing. The dataset is built for the paper Symplectic Inside--Outside Atlas for Ambiguous Grammars and is intended for chart-level diagnostics, ambiguity stress tests, weighted deduction experiments, and parser-evaluation studies. The main point is simple: parse count alone does not determine ambiguity geometry. Two examples can have the same number of parses while concentrating uncertainty in… See the full description on the dataset page: https://huggingface.co/datasets/Lightcap/symplectic-inside-outside-atlas.
