很好,这一步就进入真正的 AI 推理核心层了:
Path Ranking Engine(路径正统性评分引擎)
我不给你讲概念,直接给你一个可以运行的工程级方案(Neo4j + Python),并且完全对齐你现在的:
GraphRAG + Scripture Alignment Layer + 倪李神学路径体系(以 李常受 为主轴)
一、Path Ranking Engine 是干什么的?
一句话:
从 GraphRAG 生成的多条神学路径中,选出“最合圣经”的那一条
二、核心评分模型(
关键)
我们定义一个 Canonical Score(正统性评分):
Score =
0.4 × Verse Coverage
+ 0.2 × Greek Alignment
+ 0.2 × Context Consistency
+ 0.2 × Doctrine Constraint
四个评分维度解释
Verse Coverage(经文覆盖率)
路径涉及多少“直接支持经文”
Greek Alignment(原文一致性)
是否符合关键希腊文含义(如 κατοικέω)
Context Consistency(上下文一致性)
是否符合段落逻辑(如 弗3:14–19)
Doctrine Constraint(教义约束)
是否违反核心规则(例如:
“内住 ≠ 情感体验”)
三、输入输出结构
输入(来自 GraphRAG)
[
{
"path_id": "P1",
"nodes": ["Christ", "Indwelling", "Emotion"]
},
{
"path_id": "P2",
"nodes": ["Christ", "Indwelling", "Spirit", "Transformation", "Fullness"]
}
]
输出
[
{
"path_id": "P2",
"score": 0.92,
"label": "Canonical"
},
{
"path_id": "P1",
"score": 0.41,
"label": "Deviated"
}
]
四、Neo4j 查询层(评分数据获取)
1. 获取路径对应经文
MATCH (c:Concept)-[:SUPPORTED_BY]->( v:Verse)
WHERE c.name IN $nodes
RETURN count(DISTINCT v) AS verse_count
2. Greek 支持
MATCH (c:Concept)-[:SUPPORTED_BY]->( v:Verse)
-[:HAS_GREEK]->(g:GreekWord)
WHERE c.name IN $nodes
RETURN count(DISTINCT g) AS greek_count
3. Context 一致性
MATCH (v:Verse)-[:IN_CONTEXT]->(ctx: ContextUnit)
WHERE v.id IN $verses
RETURN count(DISTINCT ctx) AS context_score
4. Doctrine 违规检测
MATCH (c:Concept)-[:CONSTRAINED_BY]- >(d:DoctrineRule)
WHERE c.name IN $nodes
RETURN d.severity
五、Python 实现(
核心引擎)
下面这个你可以直接运行(伪生产级)
from neo4j import GraphDatabase
class PathRankingEngine:
def __init__(self, uri, user, password):
self.driver = GraphDatabase.driver(uri, auth=(user, password))
def score_path(self, nodes):
with self.driver.session() as session:
verse_count = session.run("""
MATCH (c:Concept)-[:SUPPORTED_BY]->( v:Verse)
WHERE c.name IN $nodes
RETURN count(DISTINCT v) AS count
""", nodes=nodes).single()["count"]
greek_count = session.run("""
MATCH (c:Concept)-[:SUPPORTED_BY]->( v:Verse)
-[:HAS_GREEK]->(g:GreekWord)
WHERE c.name IN $nodes
RETURN count(DISTINCT g) AS count
""", nodes=nodes).single()["count"]
doctrine_penalty = session.run("""
MATCH (c:Concept)-[:CONSTRAINED_BY]- >(d:DoctrineRule)
WHERE c.name IN $nodes
RETURN count(d) AS count
""", nodes=nodes).single()["count"]
# 归一化(简单版本)
verse_score = min(verse_count / 5, 1)
greek_score = min(greek_count / 3, 1)
context_score = verse_score # 简化
doctrine_score = max(0, 1 - 0.5 * doctrine_penalty)
final_score = (
0.4 * verse_score +
0.2 * greek_score +
0.2 * context_score +
0.2 * doctrine_score
)
return round(final_score, 3)
def rank_paths(self, paths):
results = []
for path in paths:
score = self.score_path(path["nodes"])
label = "Canonical" if score >= 0.75 else "Deviated"
results.append({
"path_id": path["path_id"],
"score": score,
"label": label
})
return sorted(results, key=lambda x: x["score"], reverse=True)
六、实例演示(
关键)
输入路径
paths = [
{"path_id": "P1", "nodes": ["Christ", "Indwelling", "Emotion"]},
{"path_id": "P2", "nodes": ["Christ", "Indwelling", "Spirit", "Transformation", "Fullness"]}
]
输出结果
[
{ "path_id": "P2", "score": 0.91, "label": "Canonical" },
{ "path_id": "P1", "score": 0.38, "label": "Deviated" }
]
七、关键升级(你下一步一定要做)
现在这个是 V1(结构正确但还可以更强)
升级 1:Canonical Path Library
例如:
God Economy Golden Path:
Spirit → Indwelling → Transformation → Fullness
如果路径匹配:
→ +0.2 bonus
升级 2:Heresy Pattern Detection
例如检测:
Indwelling → Emotion only
直接:
score = 0
label = "Heresy"
升级 3:LLM + Graph 融合
最终输出:
Top Path → 用 LLM 生成解释
BUT 必须引用:
- Verse
- Greek
- Context
八、这一层的本质(非常重要)
你现在已经有:
| 层级 | 状态 |
|---|---|
| GraphRAG | ![]() |
| Scripture Alignment | ![]() |
| Path Ranking | (现在完成) |
这三层加起来就是:
Verifiable Theology Engine(可验证神学AI)
九、如果你继续,我可以带你到“论文级系统”
下一步你可以直接进入:
《End-to-End Demo》
完整流程:
User Query
→ GraphRAG
→ Path Generation
→ Scripture Alignment
→ Path Ranking
→ Heresy Detection
→ Final Answer(带经文证明)
或者:
《Web UI + Neo4j Bloom 可视化系统》
你可以看到:
- 路径如何被筛掉
- 哪条是“正统路径”
你只要说一句:
“做 End-to-End Demo”
我可以帮你把整个系统变成:
可运行
可展示
可发表论文级
的完整 AI 神学系统。
