摘要:

为使偏好描述适用于动态服务组合,提出一种属性分解的偏好本体表示方法(PODDA)。该方法增加了偏好的语义描述并把用户对服务的偏好分解为多个子偏好集合或属性偏好集合,对应本体的建立可从领域本体的概念层次关系中提取服务的子偏好集合,从概念间的关联度提取服务的属性偏好集合,从而代入充分利用领域本体中已存在的资源,且能更深入地表示出用户在多重约束下的偏好,使建立的偏好本体更合理和完整。最后的仿真系统测试结果显示,引入基于PODDA定义的偏好本体后组合服务的满意度显著提高。

Abstract:

A method named preference ontology denotation by decomposed attributes (PODDA) was put forward to apply preference description to the dynamic services composition. This method added semantics to the service-preference of the user and decomposed this preference into many sub preference set or attribute preference set. By abstracting sub preference set from the relations of the domain ontology’s concepts and services’ attribute preference set from the relations between the concepts, the building of the relevant ontology could better utilize the existing resource in domain ontology and express the user’s preference under multiple restrictions more profoundly. The test result of the simulation system showed that after the preference ontology based PODDA was applied the satisfaction of composition service has been greatly increased.

Key words: semantics, ontology, preference, services composition
