Abstract

Service-oriented architecture has the major advantage of enabling rapid composition of distributed applications from various services, and has become increasingly popular for many large-scale service-based systems in various application areas, including scientific collaboration, e-business, health care, military, and homeland security. Situation awareness (SAW) is the capability of the entities in a service-based system to be aware of the situation changes and automatically adapt themselves to such changes to satisfy user requirements, including security and privacy. The continuing evolutions of the entities and environment makes SAW one of the most desired features to support dynamic adaptive computing in service-based systems. In this paper, the relationship between contexts/situations and services in situation-aware service-based systems is identified and an extension of OWL-S with situation ontology, called SAW-OWL-S, incorporates SAW in service specifications is presented. An approach to generating service specifications for situation-aware service-based systems using SAW-OWL-S and the system diagram of situation-aware service-based systems using SAW-OWL-S are presented

在服务规范中加入情况感知

面向服务的体系结构具有支持各种服务的分布式应用程序的快速组合的主要优点，并且在各种应用领域(包括科学协作、电子商务、医疗保健、军事和国土安全)中的许多大规模基于服务的系统中变得越来越流行。态势感知(SAW)是基于服务的系统中的实体感知态势变化并自动适应这种变化以满足用户需求(包括安全性和隐私性)的能力。实体和环境的不断发展使得SAW成为支持基于服务的系统中动态自适应计算的最理想的特性之一。本文识别了基于态势感知的服务系统中上下文/情境与服务之间的关系，并提出了一种包含态势本体的OWL-S扩展，称为SAW-OWL-S，该扩展将SAW纳入服务规范。提出了一种使用SAW-OWL-S为态势感知服务系统生成服务规范的方法，并给出了使用SAW-OWL-S的态势感知服务系统的系统图
