WSaiOS Cognitive Knowledge Network知识认知网络源码实现
45.4 Semantic Relation Engine语义关系引擎源码实现
在45.3节中,我们完成:
- Knowledge Query;
- Entity Matching;
- Relation Traversal;
- Knowledge Ranking;
- Context Retrieval。
此时WSaiOS已经能够:
Query
↓
Knowledge Graph
↓
Relevant Knowledge
但是,一个真正的认知知识网络不能只依靠人工定义关系。
它必须具备:
自动发现实体之间潜在关系的能力。
因此设计:
Semantic Relation Engine
语义关系引擎
45.4.1 Semantic Relation Engine定位
Semantic Relation Engine负责:
将:
Entity
+
Knowledge
+
Experience
转换为:
Semantic Relation
形成不断扩展的知识网络。
系统位置:

Entity Match Relation Graph
Discovery Expansion
45.4.2 Semantic Relation核心职责
包括:
(1)Relation Discovery
关系发现。
例如:
已有:
Electric Toothbrush
has_feature
Pressure Sensor
发现:
Pressure Sensor
improves
Safety
(2)Semantic Mapping
语义映射。
例如:
Fast Charging
=
Quick Charging
建立:
same_concept
(3)Relation Classification
关系分类。
判断:
属于:
- 属性关系;
- 因果关系;
- 时间关系;
- 功能关系。
(4)Graph Expansion
知识图扩展。
自动增加:
Entity

Relation

New Entity
45.4.3 Semantic Relation模块结构
目录:
semantic_relation/
├── engine.py
├── detector.py
├── mapper.py
├── classifier.py
├── expander.py
└── validator.py
45.4.4 Semantic Relation对象模型
文件:
relation_semantic.py
源码:
from dataclasses import dataclass
@dataclass
class SemanticRelation:
source:str
target:str
relation_type:str
evidence:list
confidence:float
def to_dict(self):
return {
"source":
self.source,
"target":
self.target,
"type":
self.relation_type,
"confidence":
self.confidence
}
45.4.5 Relation Discovery关系发现
核心思想:
通过:
Entity Attributes
+
Knowledge Pattern
+
Historical Experience
发现关系。
例如:
输入:
Entity A:
Electric Toothbrush
Entity B:
Pressure Sensor
属性:
A.feature=B
生成:
A
has_feature
B
源码:
class RelationDetector:
def detect(
self,
entity_a,
entity_b
):
relations=[]
for key,value in entity_a.attributes.items():
if value==entity_b.name:
relations.append(
{
"type":key
}
)
return relations
45.4.6 Semantic Mapping语义映射
目的:
解决:
不同表达代表同一概念。
例如:
AI System
Artificial Intelligence System
Intelligent System
统一:
AI System
源码:
class SemanticMapper:
def __init__(self):
self.mapping={}
def add(
self,
source,
target
):
self.mapping[source]=target
def normalize(
self,
value
):
return self.mapping.get(
value,
value
)
45.4.7 Relation Classification关系分类
WSaiOS定义:
四大关系类型:
Attribute Relation
属性关系:
Product
has_color
White
Functional Relation
功能关系:
Motor
provides
Cleaning
Causal Relation
因果关系:
Better Material
↓
Longer Life
Semantic Relation
概念关系:
SEO
related_to
Visibility
源码:
class RelationClassifier:
def classify(
self,
relation
):
if "has" in relation:
return "attribute"
if "improve" in relation:
return "causal"
return "semantic"
45.4.8 Relation Validation关系验证
自动生成关系:
必须验证。
避免:
错误知识。
验证因素:
Confidence
+
Evidence
+
Consistency
源码:
class RelationValidator:
def validate(
self,
relation
):
if relation.confidence <0.5:
return False
return True
45.4.9 Knowledge Graph Expansion
知识扩展:
流程:
Existing Knowledge

Semantic Analysis
│
▼
New Relation
│
▼
Graph Update
源码:
class GraphExpander:
def expand(
self,
graph,
relation
):
if relation:
graph.add_relation(
relation
)
return graph
45.4.10 Semantic Relation Engine核心控制器
文件:
engine.py
源码:
class SemanticRelationEngine:
def __init__(self):
self.detector=RelationDetector()
self.mapper=SemanticMapper()
self.classifier=RelationClassifier()
self.validator=RelationValidator()
def analyze(
self,
entity_a,
entity_b
):
relations=(
self.detector.detect(
entity_a,
entity_b
)
)
results=[]
for r in relations:
relation_type=(
self.classifier.classify(
r["type"]
)
)
results.append(
{
"type":
relation_type
}
)
return results
45.4.11 Semantic Relation运行示例
输入:
Entity:
Electric Toothbrush
Attribute:
Motor = Magnetic Levitation Motor
发现:
Electric Toothbrush
has_motor
Magnetic Levitation Motor
进一步:
Magnetic Levitation Motor
improves
Cleaning Efficiency
形成:
Electric Toothbrush
│
has_motor
│
