# 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``.
