The paper also introduces the concept of knowledge representation , basic principles of knowledge base , some commonly used methods of knowledge representation and knowledge base system 另外,本文還介紹了知識表示的概念、知識庫的基本原理、幾種常見的知識表示方法和知識庫系統(tǒng)。
Based on the architecture , the method of knowledge representation is a combination of production knowledge representation and relational databases in which the knowledge is represented by the relations and the storage of the knowledge is done by the database 本文在上述體系結構知識表示的實現(xiàn)上,采用產(chǎn)生式知識表示和關系數(shù)據(jù)庫相結合的知識表示方法,使用關系表示知識,使用關系數(shù)據(jù)庫存放知識。
The paper uses the object - oriented method of knowledge representation , making manifold simplex knowledge representation such as rule and frame constitute one hybrid knowledge representation form according to the object - oriented program design principle . in the object - oriented repository , the concept and entity involved in problem solving are considered as objects and expressed in the form of the framework . such a structure is good for knowledge storage and inference realization 使用了面向對象的知識表達方法,將多種單一的知識表示方法(規(guī)則、框架等)按照面向對象的程序設計原則組成一種混合知識表達形式,在面向對象的知識庫中,將問題求解中涉及的概念、實體等作為對象,并以框架形式表示,這樣的結構易于知識的存儲,也有利于推理的實現(xiàn)。
The main contributions of this paper are as follows , first , ookr , which stands for the object - oriented knowledge representation , is proposed to describe the field knowledge . as known , ookr is a hybrid method of knowledge representation , which is made with several single methods based on the object - oriented theory 主要貢獻在于:一、提出采用面向對象的知識表達模型描述領域知識,將多種單一的知識表達方法按照面向對象的原理組織,形成一種混合的知識表達方法。
During the course of compiling fault sample , multi - method of knowledge representation , as produce rule 、 frame 、 neural network representation etc are synthesized to organize and express the fault sample of pulverizing system . before being putted into the database , the sample data is disposed to ensure sample data integrity and no redundancy 在編輯制粉系統(tǒng)故障樣本過程中,作者采用了產(chǎn)生式、框架式、神經(jīng)網(wǎng)絡產(chǎn)生規(guī)則式等知識表達方法,對制粉系統(tǒng)故障診斷知識進行了有效的表達,同時對數(shù)據(jù)庫進行規(guī)范化處理,以保證數(shù)據(jù)的完整性,減少數(shù)據(jù)冗余。
