Web Technologies phần 4

một số môi trường quy mô lớn wiki có định nghĩa vai trò rộng lớn trong đó xác định những người có thể thực hiện các chức năng của bản cập nhật, phục hồi, xóa, và sáng tạo. Wikipedia, như các dự án nhiều loại wiki, có độc giả, biên tập viên, | WSBen foundation of WSBen. As a whole this article is based on two of our earlier works Kil et al. 2006 Oh Kil Lee Kumara 2006 . Extended from the previous works this article describes how WSBen is designed and works to generate test sets from the software architecture perspective and furthermore introduces three use cases to highlight the practical benefits ofWSBen. Table 1 summarizes important notations used in this article. This article is organized as follows. First in the background section we review concepts and techniques required for the WSBen development especially focusing on the complex network theory. Second in the related works section we discuss related studies in the literature as well as surveying existing world-wide challenges with regard to Web services and Semantic Web. Third in the overview of WSBen section we present WSBen with its design concept test set generation mechanism key functions and characteristics. Fourth in the use cases of WSBen section we illustrate how WSBen can be exploited to obtain research benefits especially by demonstrating three use cases. We expect three use cases enough to provide vigorous experiments and evaluation of our WSBen. Finally conclusions are provided. BACKGROUND In this section we review prerequisite techniques and concepts required to build WSBen. First we revisit the definition and complexity of Webservice discovery and composition problems. Second we introduce three complex network topologies based on which WSBen is designed to populate WSDL test files. Finally we explain our conceptual methodology to project a bipartite Web-service network consisting of three distinct nodes parameter operation and Web service and heterogeneous arc types into three distinct Web-service networks each of which consists of single node and uniform arc. The main benefit of projecting Web-service networks is that it can allow for straightforward analysis on referred network s characteristics. Throughout this article we will use
