BAAI / Zhiyuan AI Research Papers Scraper

Extract the current curated AI research paper feed from BAAI (Beijing Academy of Artificial Intelligence, 智源研究院) at hub.baai.ac.cn. Each run fetches the hotness-sorted daily paper feed and enriches every paper with full editorial curator notes written in Chinese by BAAI staff.

What You Get

Each record includes:

Field	Description
paper_title_en	Paper title in English
arxiv_id	ArXiv paper ID (e.g. 2606.06624)
authors	List of author names
publication_date	Release date (ISO 8601)
abstract_zh	Full Chinese-language abstract
keywords_zh	Chinese subject tags (e.g. 机器学习, 生成模型)
keywords_en	ArXiv category codes (e.g. cs.LG, cs.RL)
pdf_url	Direct PDF download link (BAAI-hosted mirror)
baai_curator_note	Structured editorial notes: [简介] abstract, [问题] problem addressed, [思路] key approach, [亮点] highlights, [相关] related work
baai_url	Canonical BAAI paper page URL
cited_by_count	BAAI hotness score
source	Always hub.baai.ac.cn

Why BAAI?

BAAI (智源研究院) is China's premier government-backed AI research institute, behind the WuDao foundation model series, the BGE embedding family, and the Aquila LLM. Their curated daily paper feed covers ~10–30 papers per day with Chinese-language editorial summaries not available on arXiv — the editorial value add is the key moat.

Use cases:

• Track Chinese AI research output for competitive intelligence
• Build a joinable dataset with an ArXiv scraper (shared arxiv_id key)
• Monitor BAAI's curated AI research highlights in Chinese for sino-watchers
• Feed into downstream LLM pipelines with Chinese-language summaries

Input

Parameter	Required	Default	Description
maxItems	Yes	5	Maximum number of papers to return (current feed has ~9 per run)

How It Works

1. Fetches hub.baai.ac.cn/papers — a Nuxt SSR page that embeds the current hotness feed in window.__NUXT__ state (no JavaScript execution required)
2. Extracts up to 9 paper UUIDs from the SSR data
3. Fetches each paper's detail page (hub.baai.ac.cn/paper/<uuid>) — also fully SSR-rendered
4. Merges listing data (basic fields) with detail data (curator notes, extended keywords)
5. Emits one record per paper

Note on scope: The BAAI listing page renders the current editorial feed (~9 papers) via server-side rendering. Further pagination is client-side only (infinite scroll). Each run captures the current curated snapshot — run daily to build a historical archive.

Notes

• China-hosted: The site is hosted in China. Cross-border latency is factored into timeouts (45 seconds per request). Runs from US/EU Apify datacenters may experience occasional delays.
• No authentication required: The papers feed is publicly accessible without login.
• Daily curation: BAAI curates ~10–30 papers per day. Running this actor daily gives you a rolling archive of their editorial picks.
