CQADupStack — Gaming (BEIR)

Dataset description

CQADupStack is a benchmark for community question answering (cQA) research built from Stack Exchange forums. It was introduced by Hoogeveen, Verspoor, and Baldwin at ADCS 2015. The collection spans twelve topical subcommunities (tags); each subforum is distributed with duplicate-question annotations derived from how users and moderators linked related threads. That makes CQADupStack a standard resource for studying duplicate question retrieval and related tasks over noisy, real-world Q&A text.

BEIR (Benchmarking IR, Thakur et al., NeurIPS 2021) repackages CQADupStack—along with many other public corpora—as a unified zero-shot information retrieval benchmark. BEIR treats each CQADupStack subforum (including Gaming) as a separate retrieval setting: a query is a question post, and relevant documents are other question posts marked as duplicates (or in the duplicate closure), evaluated against a corpus of posts from the same domain.

This repository (orgrctera/beir_cqadupstack_gaming) holds the Gaming slice in Parquet form for retrieval pipelines. Rows correspond to evaluation queries with relevance judgments (expected_output) pointing at corpus document identifiers from the BEIR cqadupstack-gaming corpus. The released split is test (1,595 examples), consistent with BEIR’s standard test evaluation for this subset.

Domain

The Gaming forum covers video games, platforms (e.g., PC/console), mechanics, compatibility, and performance—typical Stack Exchange Arqade–style content. Language is English.

Task: retrieval (CQADupStack Gaming)

The task is duplicate-question retrieval formulated as ad hoc retrieval:

Input: a natural-language question (the query).
Output: a ranked list of document IDs from the Gaming corpus (or scores over the full collection), such that documents judged relevant in the official qrels receive high rank.

Evaluation uses standard IR metrics (e.g., nDCG@k, Recall@k, MRR), as in BEIR’s evaluation scripts or compatible toolkits (Pyserini, ir-measures, etc.).

Note: Full retrieval evaluation requires the corpus (passages keyed by ID). Align expected_output document IDs with the same BEIR cqadupstack-gaming corpus you index for search.

Data format (this repository)

Field	Description
`id`	UUID for this example row.
`input`	The query text (question).
`expected_output`	JSON string: list of objects `{"id": "<corpus-doc-id>", "score": <relevance>}`. Scores follow BEIR qrels (typically `1` for relevant in binary settings).
`metadata.query_id`	Original BEIR / CQADupStack Gaming query identifier (string).
`metadata.split`	Split name; this dataset provides `test`.

Example 1

{
  "id": "bd7ad6eb-d9af-4f9e-b48b-2458e9e61afd",
  "input": "Are the XBLA and PC versions of Minecraft compatible?",
  "expected_output": "[{\"id\": \"143450\", \"score\": 1}]",
  "metadata.query_id": "65828",
  "metadata.split": "test"
}

Example 2

{
  "id": "99cb0b75-167c-47d9-a103-381d8e4930ec",
  "input": "How to speed up minecraft on my computer",
  "expected_output": "[{\"id\": \"14876\", \"score\": 1}, {\"id\": \"24836\", \"score\": 1}]",
  "metadata.query_id": "42307",
  "metadata.split": "test"
}

BEIR: A Heterogeneous Benchmark for Zero-shot Evaluation of Information Retrieval Models
NeurIPS 2021 (Datasets and Benchmarks Track).

Abstract (from arXiv): “Existing neural information retrieval (IR) models have often been studied in homogeneous and narrow settings, which has considerably limited insights into their out-of-distribution (OOD) generalization capabilities. To address this, and to facilitate researchers to broadly evaluate the effectiveness of their models, we introduce Benchmarking-IR (BEIR), a robust and heterogeneous evaluation benchmark for information retrieval. We leverage a careful selection of 18 publicly available datasets from diverse text retrieval tasks and domains and evaluate 10 state-of-the-art retrieval systems including lexical, sparse, dense, late-interaction and re-ranking architectures on the BEIR benchmark. Our results show BM25 is a robust baseline and re-ranking and late-interaction-based models on average achieve the best zero-shot performances, however, at high computational costs. In contrast, dense and sparse-retrieval models are computationally more efficient but often underperform other approaches, highlighting the considerable room for improvement in their generalization capabilities.”
