ComplexWebQuestions
ComplexWebQuestions is a dataset for answering complex questions that require reasoning over multiple web snippets. It contains a large set of complex questions in natural language, and can be used in multiple ways:
- By interacting with a search engine;
- As a reading comprehension task: the authors release 12,725,989 web snippets that are relevant for the questions, and were collected during the development of their model;
- As a semantic parsing task: each question is paired with a SPARQL query that can be executed against Freebase to retrieve the answer.

Papers archive 2025-07-28
5 shown of 5 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 62. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
