/novelty-check — Idea Novelty Audit (S2 + OpenAlex)

借鉴 AI-Scientist novelty check。NOVELTY gate 必备产物。

Overview

输入 idea 标题 / 一段描述，查 3 个源：

源	API
Semantic Scholar	api.semanticscholar.org/graph/v1/paper/search
OpenAlex	api.openalex.org/works?search=
arXiv	export.arxiv.org/api/query?search_query=

emit closest prior work 列表 + 相似度评分 + verdict NOVEL / OVERLAP / DUPLICATE。

Workflow

1. Extract 5 key noun phrases from idea
2. Query each source with top phrase combinations
3. Dedupe by arxiv/DOI, sort by citation count
4. Fetch top 10 abstracts via WebFetch
5. Embed-similarity vs idea (用 tools 里 simple TF-IDF cosine，不依赖外部 embed)
6. Verdict:
   • max_sim < 0.5 → NOVEL
   • 0.5 ≤ max_sim < 0.75 → OVERLAP（user 看 closest 3 篇判断）
   • ≥ 0.75 → DUPLICATE（refuse PROCEED to NOVELTY gate）

Output

idea-stage/novelty.json
{
  "verdict": "NOVEL|OVERLAP|DUPLICATE",
  "max_similarity": 0.43,
  "closest": [
    {"title":"...","authors":[...],"venue":"ICLR 2024","arxiv":"...","sim":0.43}
  ]
}
