# Research Paper Pattern Extractor

## Description
从知识图谱研究论文分析中提炼可复用的技能模式。使用 PageRank、Louvain 社区检测和向量相似度搜索识别重要论文和研究聚类，然后将研究模式提炼为新的技能。

## Activation Keywords
- extract research pattern
- research skill extractor
- 研究模式提炼
- paper pattern analysis
- 论文模式分析
- knowledge graph pattern extraction

- 学术技能提炼

## Tools Used
- **kg_tool**: 知识图谱分析工具（PageRank、Louvain、搜索）
- **sqlite3**: 直接查询 kg.db 数据库
- **read**: 读取现有技能模板和相关论文
- **write**: 创建新的 SKILL.md 文件
- **exec**: 运行 Python 脚本和命令

## Workflow

### Step 1: Analyze Knowledge Graph

使用知识图谱工具分析论文：

```bash
# 1. 检查统计信息
kg_tool stats kg.db

# 2. 运行 PageRank 找重要论文
kg_tool pagerank kg.db

# 3. 运行 Louvain 找研究聚类
kg_tool louvain kg.db

# 4. 搜索特定主题论文
kg_tool search kg.db "quantum"
kg_tool search kg.db "medical"

# 5. 向量相似度搜索（如果有向量）
kg_tool similar kg.db [entity_id]
```

### Step 2: Extract Key Papers

从 PageRank 结果中获取最重要的实体：

```bash
# 查询 Top 10 实体详情 (correct column: 'type' not 'entity_type'; table: 'entities' not 'kg_entities')
sqlite3 kg.db "SELECT id, type, name FROM entities WHERE id IN (top_ids);"
```

### Step 3: Identify Research Patterns

分析论文标题和摘要，识别模式：

1. **主题聚类**: Louvain 社区检测显示的研究方向
2. **方法论**: 重复出现的算法、技术、方法
3. **应用领域**: 医学、量子计算、金融等
4. **工具链**: Python、神经网络、模拟器等

### Step 4: Distill Skill Patterns

从论文模式提炼技能：

| Pattern Type | Skill Example |
|--------------|---------------|
| Algorithm Focus | `quantum-algorithm-optimizer` |
| Application Domain | `medical-imaging-analyzer` |
| Tool Integration | `simulation-framework` |
| Methodology | `statistical-analysis-tool` |

### Step 5: Create New Skill

生成新技能文件：

```bash
# 创建技能目录
mkdir -p skills/{skill-name}/{scripts,references}

# 创建 SKILL.md
write skills/{skill-name}/SKILL.md
```

## Cron Job Pipeline (Verified 2026-06-26)

### Full Pipeline Steps

1. **Get today's topic**: `python3 scripts/weekly_topics.py` → weekday-based theme + keywords
2. **Search arXiv**: Use `urllib.request` + `urllib.parse.quote()` (avoids security scanner blocks on curl|python pipes)
3. **Import to kg.db**: Insert into `arxiv_papers` (id, title, authors, published, categories, summary, pdf_url, abs_url) and `entities` (id, name, type, attributes JSON, importance_score, category, description, source, created_date) tables. Also `research_entities` (title, url, date, category, description, section, source) for a secondary index.
4. **Add vectors**: Keyword-based frequency vectors packed as JSON float lists into `kg_vectors` table (columns: `id` TEXT, `embedding` TEXT — NOT a blob). Use `json.dumps(vector)` not `struct.pack`.
5. **Run analysis**: `kg_tool pagerank`, `kg_tool community` (Louvain may not be available — check with `kg_tool` commands)
6. **Extract patterns**: Cross-reference high-PageRank papers with today's theme
7. **Create skills**: SKILL.md with frontmatter (name, category, description, trigger_words, source)
8. **Sync to ai_collection**: Copy to `ai_collection/collection/skills/{name}/SKILL.md`
9. **Update INDEX.md**: Append entry with arXiv ID, key points, activation keywords
10. **Git commit + push**: `git add + commit + push` to cron branch

### Critical Gotchas

- **Security scanner**: Blocks `curl | python` pipes in cron mode — use standalone Python scripts with `urllib.request`
- **arxiv query encoding**: MUST use `urllib.parse.quote()` on query strings — raw spaces/quotes cause `URL can't contain control characters`
- **kg_entities source variants**: Same paper may exist with `source='arxiv'` or `source='arxiv-cron'` from different import runs — query with `IN ('arxiv','arxiv-cron')` for completeness
- **Vector format**: `kg_vectors.vector_data` expects 128-float32 packed blobs — use `struct.pack('128f', *vector)`
- **arxiv_papers.id**: TEXT field (not integer) — store arxiv IDs as strings like '2606.23535'

### Vector Embedding Fallback (No Embedding Model)

When no embedding model is available, use keyword-frequency vectors:
```python
import struct
keywords = ['quantum', 'number', 'theory', 'statistics', 'optimization', ...]
text = (title + ' ' + summary).lower()
vector = [text.count(kw) / max(len(text.split()), 1) for kw in keywords]
vector = vector + [0.0] * (128 - len(vector))  # Pad to 128
vector_bytes = struct.pack('128f', *vector)
cursor.execute('INSERT INTO kg_vectors (entity_id, vector_data) VALUES (?, ?)', (entity_id, vector_bytes))
```

## Key Metrics

分析知识图谱时关注：

- **Entity Count**: 论文总数
- **Relation Count**: 关系总数
- **Avg Degree**: 平均连接度
- **PageRank Score**: 论文重要性
- **Community ID**: 研究聚类归属

## Best Practices

### 1. 多维度分析
结合 PageRank + Louvain + 向量搜索，全面理解研究结构

### 2. 跨领域发现
寻找跨学科研究（量子 + 医学、AI + 金融等）

### 3. 技能验证
创建新技能后测试其实用性

### 4. 持续更新
定期分析新论文，更新技能库
