The hyponymy hierarchy is an essential part of domain knowledge, which is widely used in many applications. With the development of the Internet, the World Wide Web is now an invaluable resource of hyponymy discovering. However, acquiring domain hyponymy hierarchy from the web is still a low efficient work, because the hyponymy acquiring process is often disturbed by numerous irrelevant terms. In...
Modeling plays a crucial role in model-driven development of service-oriented systems. This paper proposes a framework for service-oriented modeling that combines an agent-oriented software development methodology with an ontology-based domain analysis technique. It aims at improving the dynamic composability of services at requirements and design stages through modeling. The framework consists of...
It is now well-accepted that formal methods are helpful for many problems raised in Web Service area. In this paper, we propose a new process algebra to formalize the environment-based specification of Web Services. From our point of view, the capability of a Web Service is considered in terms of the effects it imposes on the environment during its execution. The environment is composed of numbers...
Software requirements, especially non-functional requirements, are considered as vital prerequisites for producing software of high quality. As widely accepted, non-functional goal modeling like the NFR Framework usually employs tree modeling style, and presents an interactive process for the analysis of nonfunctional requirements. However, there still exist some problems during the identification...
One fundamental problem in services computing is how to bridge the gap between business requirements and various heterogeneous IT services. This involves eliciting business requirements and building a solution accordingly by reusing available services. While the business requirements are commonly elicited through use cases and scenarios, it is not straightforward to transform the use case model into...
Non-functional requirements are considered as vital factors for producing software of better quality. As a widely adopted non-functional requirements analysis framework, the NFR Framework provides a graphical treatment for goal refinement and evaluation. This paper propose a logical representation for the NFR Framework. In addition, an NFR extension operator and an accompanying extension function...
