+## 📦 数据集内容 · What's in this dataset
+
+| 路径 Path | 格式 Format | 说明 Description |
+|---|---|---|
+| `cache/cache.jsonl.gz` | gzip-compressed JSON Lines (UTF-8) | 每行一篇论文 · One paper per line; one JSON object per line |
+
+Hugging Face 会自动为 `cache.jsonl.gz` 生成 Parquet 视图，也可直接用 `datasets.load_dataset(...)` 读取，无需手动解压。Hugging Face also exposes an auto-generated Parquet view, so `datasets.load_dataset(...)` works out of the box.
+
+### 📐 字段 Schema
+
+| Field 字段 | Type 类型 | Notes 说明 |
+|---|---|---|
+| `paper_name` | string | 论文标题（已归一化）· Normalised paper title |
+| `paper_authors` | list[string] | 作者列表，按原始顺序 · Author names in order |
+| `paper_url` | string | 论文在原始平台的链接（PDF 或落地页）· Canonical URL on the venue's site (PDF or landing page) |
+| `paper_abstract` | string | 摘要；未回填时为空字符串 · Abstract; may be empty when not yet backfilled |
+| `paper_code` | string | 从摘要中抽取出的 GitHub 仓库 URL；`"#"` 是「未发现代码链接」的占位符 · GitHub repository URL extracted from the abstract; `"#"` is the sentinel for "no code link discovered" |
+| `conf` | string | 会议+年份标识，如 `ACL2024`、`NIPS2023`、`CVPR2025`；去掉末尾四位数字即可得到会议系列。注意 NeurIPS Proceedings 沿用历史命名 `NIPS{year}`。Venue + year identifier (e.g. `ACL2024`, `NIPS2023`, `CVPR2025`). Strip the trailing 4-digit year to recover the venue series. Note that NeurIPS Proceedings entries use the historical name `NIPS{year}`. |
+
+> 缺失字段请按空字符串处理。Treat missing fields as empty strings.

+
+## ⬇️ 获取方式 · How to download
+
+下面三种方式任选其一即可，**无需克隆 GitHub 仓库**。Pick any one of the three options below — **no GitHub clone is required**.
+
+#### 方式 A · Option A — `huggingface_hub`（推荐 / recommended）
+
+```python
+from huggingface_hub import hf_hub_download
+import gzip, json
+
+path = hf_hub_download(
+    repo_id="youngfish42/PaperVault",
+    filename="cache/cache.jsonl.gz",
+    repo_type="dataset",
+)
+
+with gzip.open(path, "rt", encoding="utf-8") as f:
+    for line in f:
+        record = json.loads(line)
+        # 在这里处理一条记录 · do something with the record
+```
+
+#### 方式 B · Option B — `datasets`
+
+```python
+from datasets import load_dataset
+
+ds = load_dataset("youngfish42/PaperVault")
+print(ds[next(iter(ds))][0])
+```
+
+> 数据集只有一个默认 split（非 ML 训练集），不要传 `split="train"`。Single default split — do **not** pass `split="train"`.
+
+#### 方式 C · Option C — `huggingface-cli` / 直接 HTTPS · Plain HTTPS
+
+```bash
+huggingface-cli download youngfish42/PaperVault \
+    cache/cache.jsonl.gz --repo-type dataset --local-dir ./data
+```
+
+> 💡 文件压缩后约 120 MB（会随数据持续增长），解压后是 GB 级 JSONL 流，请按行流式读取，不要整体载入内存。The file is ~120 MB compressed (and growing) and decompresses to a multi-GB JSONL stream. Stream it line-by-line rather than loading the whole thing into memory.
+

+
+## 🔁 更新节奏 · Update cadence
+
+数据集由三个 GitHub Actions 工作流负责重建并推送到本 Hub 仓库 / The dataset is rebuilt and pushed to this Hub repo by three GitHub Actions workflows：
+
+| 工作流 Workflow | 触发节奏 Schedule | 推送的内容 What it pushes |
+|---|---|---|
+| `collect_papers` | 每月 15 号 16:00 UTC + 手动触发 · 15th of every month at 16:00 UTC + `workflow_dispatch` | 增量抓取新发现的会议/年份组合 · Incremental crawl of newly-discovered conference/year combinations |
+| `backfill_abstracts` | 每月 1 号 00:00 UTC + 手动触发 · 1st of every month at 00:00 UTC + `workflow_dispatch` | 为已有论文回填 `paper_abstract` · Adds `paper_abstract` for papers that were collected without one |
+| `update_readme` | 仅手动触发 (`workflow_dispatch`) · Manual only (`workflow_dispatch`) | 默认仅刷新 README 与统计；当输入参数 `mode=force` 时执行全量重建 · Refreshes the README and statistics by default; performs a full rebuild only when invoked with `mode=force` |
+
+每次推送都使用 Hugging Face 的 `parent_commit` 乐观锁机制，避免并发覆盖。Each push uses Hugging Face's `parent_commit` optimistic-lock mechanism to avoid silently overwriting concurrent updates.
