Abstract

Based on ontologies, semantic Web services enable the discovery, selection, and composition. OWL-S is a do facto standard ontology for describing semantics of Web services. Due to the difficulty of the OWL-S grammar, the teaming curve for constructing OWL-S description manually can be steep. This paper presents an efficient method for generating OWL-S descriptions from UML diagrams, which are widely used for software design and development. The proposed method is based on UML profiles to generate an OWL-S ontology from sequence or activity diagrams, which represent the behavior of a business process. Specifically, an XMI file extracted from UML diagrams is transformed into an OWL-S description via an XSLT script. Experimental results with a large volume of UML diagrams show that the proposed method deals with the control flow of complex processes and is superior to previous methods.

온톨로지에 기반한 시맨틱 웹 서비스는 웹 서비스의 자동화된 탐색, 선택, 조합을 지원한다. 특히 시맨틱 웹 서비스 기술 표준인 OWL-S는 서비스의 의미적 기술을 제공하기 위해 만들어진 온톨로지 언어이다. 한편 OWL-S는 문법이 복잡하여 일반 사용자가 OWL-S 문서를 직접 생성하는 것은 어렵다. 본 논문에서는 현재 소프트웨어 설계 및 개발을 위해서 널리 사용 중인 UML 다이어그램으로부터 OWL-S 문서를 편리하게 생성할 수 있는 방법을 제안한다. 제안한 방법은 프로세스의 흐름을 기술한 순차 다이어그램 및 활동 다이어그램으로부터 OWL-S 온톨로지를 생성하기 위해서 UML 프로파일을 기반으로 하고 있다. UML 다이어그램은 XMI 파일로 추출되고 XSLT 스크립트를 통해 OWL-S 온톨로지로 변환된다. 제안한 방법은 복합 프로세스의 다양한 제어구조를 지원할 수 있는데, 이 논문에서는 다양한 종류의 UML 다이어그램을 대상으로 실험함으로써 이를 보였다.
