# websrc

WebSRC HTML-only native yes/no and DOM-element supervision (CC BY 4.0).

Original HTML is preserved. Native website-level train/dev splits are retained;
no test labels are consumed or evaluation splits fabricated. Element choices
are all nonempty native DOM elements, capped at 128 by excluding larger pages.
Span offsets and deepest-element evidence are checked before inclusion. No
generated distractors. Deterministic bounded samples cover each eligible source.

Original data: [X-LANCE/WebSRC_v1.0](https://huggingface.co/datasets/X-LANCE/WebSRC_v1.0). Repackaged as parquet for [tasksource](https://github.com/sileod/tasksource) by [scripts/repackage_dataset/](https://github.com/sileod/tasksource/tree/main/scripts/repackage_dataset).

## Release scope

Bounded samples of the eligible native annotations; full classification ontologies are retained.

- yesno: train: 1,000, validation: 100.
- element: train: 1,000, validation: 100.
