摘要

情境感知網際服務技術是網際服務以及網際服務使用者的情境資訊兩者交互影響下的一種模型。我們認為，要朝向無所不在的網際服務，其第一個步驟，就是要能提供情境感知的網際服務。情境感知的網際服務可以藉著在對的時間，對的地點找到適合的商業夥伴、適合的商業資訊以及適合的商業服務，這樣可以改善現有電子化的企業服務。本篇論文最主要的貢獻，就是使用了情境模型來表達服務的描述以及使用情境感知之服務導向架構來完成網際服務的發現。我們利用情境模型來正規的描述以及取得網際服務與網際服務使用者的情境資訊。此外，我們也利用此情境模型為基礎發展了情境感知之服務導向架構，這個架構可以根據網際服務及其使用者的情境協助無所不在網際服務的發現以及存取。

Context-aware Web service is an interactive model between the context of service requesters and the services. We envision that providing context-aware services is the first step toward ubiquitous Web services to enhance current e-business by finding right business partners, right business information, and right business services in the right place at the right time. The major contributions of this thesis are the development of our context model for services description and Context Aware Service Oriented Architecture (CA-SOA) for services discovery. We have developed a context model to formally describe and acquire contextual information pertaining to the service requesters and services. Based on the model, we have constructed CA-SOA for ubiquitous Web service discovery and access based on service and requesters’ surrounding context.
