WikiQA (Wikipedia open-domain Question Answering)

Introduced by Yi Yang et al. in WikiQA: A Challenge Dataset for Open-Domain Question Answering1 Jan 2015 archive 2025-07-28

The WikiQA corpus is a publicly available set of question and sentence pairs, collected and annotated for research on open-domain question answering. In order to reflect the true information need of general users, Bing query logs were used as the question source. Each question is linked to a Wikipedia page that potentially has the answer. Because the summary section of a Wikipedia page provides the basic and usually most important information about the topic, sentences in this section were used as the candidate answers. The corpus includes 3,047 questions and 29,258 sentences, where 1,473 sentences were labeled as answer sentences to their corresponding questions.

19 shown of 19 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 196. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
