# 🔍 质量控制与自我纠正机制
|
||
|
||
为机场智能化 wiki 建立**多层次质量验证**和**自动纠错**系统，确保技术参数准确、内容一致、关系完整。通过规则检查、语义验证和用户反馈，实现持续质量改进。
|
||
|
||
> **质量目标**：零技术参数错误，内容一致性 >95%，关系完整性 >90%，用户满意度 >85%。

## 🏗️ 质量框架层次
|
||
|
||
### 层次 1: **语法与格式检查** (Syntax & Format)
|

| 检查项 | 规则 | 自动修复 | 严重性 |
|
||
|--------|------|----------|--------|
|
||
| **Markdown 语法** | 链接格式、标题层级、列表 | ✅ 自动修复 | 低 |
|
||
| **YAML 前端元数据** | 必需字段、类型验证 | ✅ 自动修复 | 中 |

|
||
|--------|------|----------|--------|
|
||
| **事实冲突检测** | 矛盾陈述识别 | ❌ 人工审核 | 高 |

|
||
|--------|------|----------|--------|
|
||
| **死链检测** | 内部链接有效性 | ✅ 自动修复 | 中 |
