This is a modest extension of prior embedding-versus-graph work, and the paper earns credit for trying to surface potential complementarity between the two approaches on a real citizen-contribution dataset.\n\nThe soft spots are substantial and load-bearing. The abstract supplies no metrics, error bars, alignment procedure between discrete graphs and continuous vectors, or controls for supervision effects, so the local-versus-global distinction cannot be assessed. The premise that co-occurrence graphs encode semantic relations more directly than CamemBERT is stated but neither defined nor tested; without that grounding, any reported structural difference could stem from mismatched inductive biases rather than model class. Methods for extracting and comparing topologies are described only at the level of intention.\n\nThis is for readers already working on interpretability of semantic geometries who want one more corpus-level case study. It does not yet contain the concrete evidence or falsifiable steps needed for a serious referee process.
