websrc-spans

WebSRC v1.0 span questions over the visible text of each web page (CC BY 4.0).

WebSRC (Chen et al., EMNLP 2021) has crowd-written questions over 6.4k web page segments; span answers are the annotated DOM element plus a character offset into its text. Each page's HTML is converted to visible text (VisibleText: decoded entities, collapsed whitespace, one line per block element, ' | ' between table cells) and every span answer is relocated in the answer element's range of that text, verified verbatim. Yes/no questions are not spans and are left out (the tasksource/websrc yes/no config holds them); unlocatable answers are dropped with a reason, never turned into nulls. One row per page groups its questions. Native website-disjoint splits: train and dev (validation) from the train+dev archive, test from the test archive with the answers released in WebSRC_v1.0_test_answers.json.

Original data: X-LANCE/WebSRC_v1.0, original distribution. Repackaged as parquet for tasksource by scripts/repackage_dataset/web_extraction.py.

Conversion provenance: source revisions, hashes, configuration and exclusions.
