WSaiOS Cognitive Knowledge Network知识认知网络源码实现

45.5 Cognitive Reasoning Engine认知推理引擎源码实现

在45.4节中,我们完成:

  • Relation Discovery;
  • Semantic Mapping;
  • Relation Classification;
  • Knowledge Graph Expansion。

此时WSaiOS已经具备:

Entity

+

Relation

+

Knowledge Graph

+

Semantic Connection

但是:

知识连接并不等于智能。

人工认知系统必须能够:

基于已有知识关系,推导新的认知结果。

因此设计:

Cognitive Reasoning Engine

认知推理引擎


45.5.1 Reasoning Engine定位

Cognitive Reasoning Engine负责:

从:

Existing Knowledge

产生:

New Conclusion

系统位置:


          Knowledge Network


                  │


                  ▼


       Cognitive Reasoning Engine


                  │


        ┌─────────┼─────────┐


        ▼         ▼         ▼


     Decision   Planning   Agent


45.5.2 Reasoning Engine核心能力

WSaiOS定义五类推理:


(1)Rule Reasoning

规则推理。

根据:

IF

Condition


THEN

Conclusion

例如:

IF

Battery Low


THEN

Need Charging

(2)Knowledge Path Reasoning

知识路径推理。

例如:

A

↓

B

↓

C

得到:

A related to C

(3)Causal Reasoning

因果推理。

例如:

Poor Material

↓

Short Life

↓

Customer Complaint

(4)Multi-Hop Reasoning

多跳推理。

例如:

Product

↓

Feature

↓

Benefit

↓

Customer Value

(5)Context Reasoning

上下文推理。

结合:

  • 当前任务;
  • 历史经验;
  • 环境状态。

    conclusion:str


    confidence:float


    path:list


    evidence:list



    def to_dict(self):


        return {


        "conclusion":

        self.conclusion,


        "confidence":

        self.confidence,


        "path":

        self.path,


        "evidence":

        self.evidence


        }

45.5.5 Rule Reasoning规则推理

文件:

rule_reasoner.py

源码:

class RuleReasoner:



    def reason(
            self,
            rule,
            context
    ):


        if self.match(

            rule,

            context

        ):


            return rule.conclusion



        return None



    def match(
            self,
            rule,
            context
    ):


        return True

示例:

规则:

IF

Product Certificate Exists


THEN


Increase Trust Score

输入:

Certificate=True

输出:

Trust Score Increase

45.5.6 Knowledge Path Reasoning知识路径推理

核心:

寻找:

Entity之间路径。

例如:


Customer


 ↓


Preference


 ↓


Product Feature


 ↓


Recommendation


源码:

class PathReasoner:



    def find_path(
            self,
            graph,
            start,
            end
    ):


        path=[]


        for relation in graph.relations:


            if relation.source==start:


                path.append(

                    relation

                )


        return path

45.5.7 Multi-Hop Reasoning多跳推理

流程:


Entity A


 ↓


Relation


 ↓


Entity B


 ↓


Relation


 ↓


Entity C


源码:

class MultiHopReasoner:



    def infer(
            self,
            graph,
            entity,
            depth=3
    ):


        result=[]



        current=entity



        for i in range(depth):


            relations=(

            graph.find(

                current

            )

            )


            result.extend(

                relations

            )



        return result

45.5.8 Causal Reasoning因果推理

WSaiOS使用:

Causal Relation。

例如:

知识:

Low Quality Material

        causes

Short Product Life

推理:

Avoid Low Quality Material

源码:

class CausalReasoner:



    def analyze(
            self,
            relation
    ):


        if relation.type=="causal":


            return {


            "cause":

            relation.source,


            "effect":

            relation.target


            }

45.5.9 Reasoning Trace推理轨迹

WSaiOS要求:

所有推理必须可追踪。

结构:

Conclusion

文件:

trace.py

源码:

class ReasoningTrace:



    def __init__(self):


        self.steps=[]



    def add(
            self,
            step
    ):


        self.steps.append(

            step

        )



    def get(self):


        return self.steps

45.5.10 Cognitive Reasoning Engine核心控制器

文件:

engine.py

源码:

class CognitiveReasoningEngine:



    def __init__(self):


        self.rule_reasoner=RuleReasoner()


        self.path_reasoner=PathReasoner()


        self.causal_reasoner=CausalReasoner()



    def reason(
            self,
            knowledge,
            context
    ):


        results=[]



        rule_result=(

        self.rule_reasoner.reason(

            knowledge,

            context

        )

        )


        if rule_result:


            results.append(

                rule_result

            )



        return results
