基于演化传播模型的本体内聚程度分析

本体演化是本体工程领域的研究热点之一,当前研究大多侧重于演化策略或演化过程中使用的技术的研究,对于如何最化本体适应变化的能力至今没有明确结论,本文从一个全新的角度来解决这一问题,通过计算给定本体的内聚程度来量化本体适应变化的能力.本文提出了一种包含本体变更影响信息的演化传播模型；定义了能使该模型形式化表示的编码ETMC...

Ontology Cohesion Analysis Based on Change Transmissibility Model

Ontology evolution is a research hotspot in ontology engineering.Nowadays,most of the researches are related with evolution strategies and the technology used in evolution,but there are no clear conclusions for the problem how to scale the ability of ontologies for evolution.This paper solves the problem from a new point of view,that it uses ontology cohesion to determine the degree of ontology evolution.We propose a new Change Transmissibility Model that contains the information of ontology evolution;we define an encoding method called ETMC,which is used to represent the model;we analyze the factors that affect the ontology cohesion and propose an approach to compute the ontology cohesion based Change Transmissibility Mode and ETMC encoding method;we carry out our experiments on two ontologies which describe the same domain knowledge,and the experimental results show that our approach is feasible on the problem of determining the ability of ontology evolution.
