| ## OpenResearcher Gold Documents |
|
|
| This dataset contains the **gold documents** used for the "Gold Document Retrieval via Online Bootstrapping" step described in Section 3.2 of the [OpenResearcher paper](https://arxiv.org/abs/2603.20278). Gold documents are documents that collectively contain sufficient evidence to derive the ground-truth answer for a given question. |
|
|
| For **6,102** questions sourced from [MiroVerse](https://huggingface.co/datasets/miromind-ai/MiroVerse-v0.1), we constructed a search query by concatenating the question and reference answer, retrieved web content via the Serper API, and cleaned/deduplicated the results to obtain **~10K gold documents** (1–3 gold documents per question, averaging 2.86). |
|
|
| These gold documents are merged with 15M FineWeb documents (as distractors) to build the offline search corpus, [OpenResearcher-Corpus](https://huggingface.co/datasets/OpenResearcher/OpenResearcher-Corpus), which is used as a self-hosted, API-free search engine when synthesizing the deep-research trajectories released as [OpenResearcher-Dataset](https://huggingface.co/datasets/OpenResearcher/OpenResearcher-Dataset). This bootstrapping step is essential: removing it causes gold-document hit rate to drop from 29.54% to 1.73%, trajectory accuracy to drop from 56.86% to 43.81%, and downstream BrowseComp-Plus accuracy to collapse from 54.81% to 6.35% (see RQ2 in the paper). |
|
|
| ## Format |
|
|
| Each row in the dataset contains the following fields: |
| - **query_id** (int64): A unique identifier for each question. |
| - **query** (string): The original question, sourced from [MiroVerse](https://huggingface.co/datasets/miromind-ai/MiroVerse-v0.1). |
| - **answer** (string): The reference answer used to construct the retrieval query. |
| - **gold_docs** (list): The gold documents retrieved and cleaned for this question. Each entry contains: |
| - **position** (int64): Rank position among the retrieved gold documents. |
| - **text** (string): The full text content of the gold document. |
| - **url** (string): The source URL where the document was retrieved from. |
| - **pass_rate** (float64): The pass rate observed for this question during trajectory synthesis with GPT-OSS-120B. |
| |
| ## How to use this dataset? |
| |
| ```python |
| from datasets import load_dataset |
| |
| ds = load_dataset("OpenResearcher/OpenResearcher-Corpus-Gold-Doc", split="train") |
| row = ds[0] |
| print(row["query"]) |
| print(row["answer"]) |
| for doc in row["gold_docs"]: |
| print(doc["url"], doc["text"][:200]) |
| ``` |
