财务报表分析专家系统知识库的设计与实现

针对传统的规则式财务金融与会计领域的专家系统无法完整呈现较庞杂的知识内容的问题,提出将知识库分成领域知识及运作知识的设计方法.首先采用本体论建模领域知识,并结合基于框架与基于规则的方法建立运作知识,最后实现了领域知识与运作知识在执行中相互沟通的机制.以此知识库为基础设计了财务报表分析专家系统,提高了知识库的可再用性、可理解性与可扩充性.

Design and Implementation of Knowledge Base in Financial Statement Analyzing Expert System

The traditional way in designing an expert system in finance and accounting is rule-based,once the knowledge content becomes huge and complex,this kind of design may cause some problems.A design methodology was proposed which separating knowledge of a problem domain into domain knowledge and operational knowledge.Ontology was applied to model the domain knowledge,frames and rules were applied to establish the operational knowledge,and Java was applied to integrate the two by providing necessary communication mechanisms during the execution phase.This design methodology facilitates the reusability,understandability,and extendibility of the knowledge base.
