# Academic Literature Search — 学术文献检索与引用管理

Use this skill when the user asks to search for academic papers, retrieve literature, generate citations, format references, or any task involving PubMed, bioRxiv, arXiv, or academic reference management. Trigger keywords: "搜文献", "检索", "找论文", "参考文献", "引用", "citation", "search papers", "PubMed", "bioRxiv", "arXiv", "GB/T 7714", "PMID", "DOI", "批量引用".

## Core Principles

1. **MCP first, Python second**: PubMed operations → MCP tools (zero code). Python only for arXiv, GB/T 7714 formatting, and citation post-processing.
2. **Code-driven citations**: Citation formatting, validation, deduplication, renumbering — ALL via Python code. NEVER fabricate PMIDs, DOIs, author names, or journal names.
3. **GB/T 7714-2015 sequential numbering**: `[1][2][3]` in-text, references numbered by order of first appearance.
4. **Journal name consistency**: Use **full journal names** throughout (NOT ISO abbreviations). E.g., `Nature Medicine` not `Nat Med`. If MCP returns abbreviated names, expand them; if expansion is uncertain, use the name as returned.

## Tool Routing Decision Table

| 操作 | 用什么 | 为什么 |
|------|--------|--------|
| PubMed 关键词搜索 | **MCP** `pubmed_search_articles` | 原生日期/类型过滤/排序，Agent 零代码 |
| PMID 批量获取详情 | **MCP** `pubmed_fetch_contents` | 4种详情级别，一次200个，含 MeSH |
| 相似论文发现 | **MCP** `pubmed_article_connections` (similar) | 直接调用，返回结构化数据 |
| 被引论文发现 | **MCP** `pubmed_article_connections` (citedin) | 同上 |
| 论文参考文献（它引了谁） | **MCP** `pubmed_article_connections` (references) | **MCP 独有**，ELink 不支持 |
| RIS/BibTeX 导出 | **MCP** `pubmed_article_connections` (citation_formats) | 内置格式化 |
| bioRxiv/medRxiv 搜索 | **MCP** `pubmed_search_articles` + journal filter | queryTerm 加 `biorxiv[journal]` |
| arXiv 搜索 | **Python** | MCP 不覆盖 arXiv |
| GB/T 7714-2015 格式化 | **Python** | MCP 无国标格式 |
| 引用后处理/去重/编号 | **Python** | MCP 不覆盖 |

## Python Operations

### arXiv 搜索

Uses stdlib only (`urllib.request` + `xml.etree.ElementTree`), no external dependencies:

```python
import urllib.request, urllib.parse, xml.etree.ElementTree as ET, re

def _parse_author_name(full_name):
    """Convert 'Shunyu Yao' → 'Yao S' (GB/T 7714: surname first, initials)."""
    parts = full_name.strip().split()
    if not parts:
        return full_name
    if len(parts) == 1:
        return parts[0]
    surname = parts[-1]
    initials = "".join(p[0].upper() for p in parts[:-1])
    return f"{surname} {initials}"


def search_arxiv(query, max_results=10):
    """Search arXiv. Free API, no key needed. Uses only stdlib."""
    params = urllib.parse.urlencode({
        "search_query": f"all:{query}", "start": 0,
        "max_results": max_results, "sortBy": "relevance",
        "sortOrder": "descending"
    })
    url = f"https://export.arxiv.org/api/query?{params}"
    with urllib.request.urlopen(url, timeout=30) as resp:
        xml_text = resp.read().decode("utf-8")

    ns = {"atom": "http://www.w3.org/2005/Atom",
          "arxiv": "http://arxiv.org/schemas/atom"}
    root = ET.fromstring(xml_text)
    articles = []
    for entry in root.findall("atom:entry", ns):
        title = (entry.findtext("atom:title", "", ns) or "").replace("\n", " ").strip()
        abstract = (entry.findtext("atom:summary", "", ns) or "").replace("\n", " ").strip()

        raw_authors = [a.findtext("atom:name", "", ns).strip()
                       for a in entry.findall("atom:author", ns)]
        authors_gbt = [_parse_author_name(a) for a in raw_authors]

        published = entry.findtext("atom:published", "", ns)[:10]
        id_url = entry.findtext("atom:id", "", ns) or ""
        arxiv_id = id_url.split("/abs/")[-1] if "/abs/" in id_url else ""

        doi_e = entry.find("arxiv:doi", ns)
        doi = doi_e.text.strip() if doi_e is not None and doi_e.text else ""

        cat_e = entry.find("arxiv:primary_category", ns)
        cat = cat_e.get("term", "") if cat_e is not None else ""

        articles.append({
            "source": "arxiv", "pmid": "", "doi": doi, "arxiv_id": arxiv_id,
            "title": title, "authors": authors_gbt,
            "journal": f"arXiv:{arxiv_id}",
            "year": published[:4] if published else "",
            "volume": "", "issue": "", "pages": "",
            "abstract": abstract,
            "url": f"https://arxiv.org/abs/{arxiv_id}",
            "category": cat,
            "venue": "",  # populated manually for published conference papers
        })
    return articles
```

#### GB/T 7714 常见会议论文示例

写综述 §3 时，ReAct 等 ML 会议论文应标注为 [C]：

```
[N] Yao S, Zhao J, Yu D, et al. ReAct: synergizing reasoning and acting in language models[C]//International Conference on Learning Representations (ICLR), 2023.
[N] Wei J, Wang X, Schuurmans D, et al. Chain-of-thought prompting elicits reasoning in large language models[C]//Advances in Neural Information Processing Systems (NeurIPS), 2022.
```

要自动生成这种格式，需要在 article dict 中设置 `venue` 字段：
```python
article["venue"] = "International Conference on Learning Representations (ICLR)"
article["doc_type"] = "conference"
```

对于 arXiv 论文已被会议收录的情况（如 ReAct 先发 arXiv 后收录于 ICLR），应优先使用会议格式 [C]，而非预印本格式 [Z/OL]。Agent 在写综述时需要根据论文的最终发表状态判断使用哪种格式。

### 引用后处理

```python
import re

def process_citations(body, sources):
    """Post-process LLM-written text:
    1. Expand [1,2,3] → [1][2][3]
    2. Collect cited IDs in order of first appearance
    3. Remap to sequential numbering
    4. Remove phantom citations (IDs not in sources)
    """
    # Step 1: Expand multi-citations
    body = re.sub(
        r"\[(\d+(?:\s*,\s*\d+)+)\]",
        lambda m: "".join(f"[{n.strip()}]" for n in m.group(1).split(",")),
        body
    )

    # Step 2: Collect valid cited IDs in order of first appearance
    seen, ordered = set(), []
    for m in re.finditer(r"\[(\d+)\]", body):
        n = int(m.group(1))
        if n not in seen and 1 <= n <= len(sources):
            seen.add(n)

    # Step 3: Build remap and reference list
    remap = {old: new for new, old in enumerate(ordered, 1)}
    cited_sources = [sources[old - 1] for old in ordered]

        return f"[{remap[n]}]" if n in remap else ""
    body = re.sub(r"\[(\d+)\]", _remap, body)
    body = re.sub(r"  +", " ", body)

    return body, refs, cited_sources


def deduplicate(articles):
    """Deduplicate by DOI > PMID > normalized title."""
    seen = set()
    unique = []
    for a in articles:
        key = ((a.get("doi") or "").strip() or
               (a.get("pmid") or "").strip() or

## Typical Workflows

### "搜文献" — 关键词检索
1. MCP `pubmed_search_articles`（主力）
2. Python `search_arxiv()`（CS/AI 领域补充）
3. 合并 + `deduplicate()`
4. 展示表格

### "把这些 PMID 转成引用格式"
1. MCP `pubmed_fetch_contents` (pmids=[...], detailLevel="abstract_plus")
2. Python `format_gbt7714()` 逐条格式化
3. 输出 + 写文件

### "这篇论文的引用网络"
1. MCP `pubmed_article_connections` (similar) → 相似论文
2. MCP `pubmed_article_connections` (citedin) → 谁引了它
3. MCP `pubmed_article_connections` (references) → 它引了谁
4. 合并展示

### "bioRxiv 上关于 X 的预印本"
1. MCP `pubmed_search_articles` (queryTerm="X AND biorxiv[journal]")
2. 展示结果

## Dependency

All Python code uses ONLY stdlib (`urllib.request`, `xml.etree.ElementTree`, `re`, `json`). **Zero external dependencies**.
