Web services are programs which perform some elementary business process of an application and are distributed over the Internet. These services are described, discovered and executed using standard languages WSDL, SOAP and UDDI. Proliferation of web services has resulted in intense competition between providers, which provide the same service. To survive in such a competitive environment, they need to advertise the quality of their service. Web service description language does not provide support to describe quality attributes. Recently, DAmbrogio proposed QOS model of web services based on a meta model of WSDL. In this paper, we present a platform to advertise QOS as declared by the service provider. This tool generates a WSDL file from Java code along with its quality of service attributes. It accepts Java code and a file containing quality attributes. These attributes include reliability, availability, and operation demand and operation latency. These attributes are included in WSDL file as a content of description element.

Implementation Stage

The development, registration, discovery, and invocation of quality Web services are vital for the successful implementation of applications using Web services. Considerable research focuses on quality for Web services. Unfortunately, current research on Quality of Service (QoS) for Web services is concentrated on service users and the implementation stage. This research highlights the importance of incorporating QoS at the design and development stages; the authors propose the introduction of QoS at the same time as functional requirements. However, Web Service Description Language (WSDL) describes the functional elements of a Web service, and QoS is significant for this description. Therefore, the authors propose an extension to the WSDL through a generic QoS metamodel, incorporating QoS specifications into the functionalities. This paper begins by defining the required QoS specifications for the development of quality Web services and explores the potential of the Unified Modeling Language as a technique and notation to specify QoS. To properly integrate QoS in the design, the authors propose extensions to the existing UML QoS profile. The paper concludes with the evaluation of the proposed framework and summarises its advantages.

Priori Information

Web Services (WS) are fundamental software artifacts for building service oriented applications and they are usually reused by others. Therefore they must be analyzed and comprehended for maintenance tasks: identification of critical parts, bug fixing, adaptation and improvement. In this article, WSDLUD a method aimed at measuring a priori the understanding degree (UD) of WSDL (Web Service Description Language) descriptions is presented. In order to compute UD several criteria useful to measure the understanding?s complexity of WSDL descriptions must be defined. These criteria are used by LSP (Logic Scoring of Preference), a multicriteria evaluation method, for producing a Global Preference value that indicates the satisfaction level of the WSDL description regarding the evaluation focus, in this case, the understanding degree. All the criteria information required by LSP is extracted from WSDL descriptions by using static analysis techniques and processed by specific algorithms which allow gathering semantic information. This process allows to obtain a priori information about the comprehension difficulty which proves our research hypotheses that states that it is possible to compute the understanding degree of a WSDL description.

In Table Tennis match information processing, Match Information needs processing through Web service, The corresponding concepts need to be published and shared by the semantic web, the Web Service description language (WSDL) has become a XML recommendation to publish and share concepts on the semantic web. In order to derive hidden information of Table Tennis information concept. In this paper, we propose an reinforced method of optimizing the Table Tennis information process of concept reasoning. Our work focuses on one key aspects: we describe classical methods for Table Tennis information concepts category. it is important to ensure that the category process uses the smallest number of tests. Therefore, we consider reinforced method and evaluate their effect on four different types of test concept.

Web Services and Service Oriented Computing (SOC) paradigm have received significant attention due to its wide spread adoption and promotion by major IT vendors. As more and more Service-Oriented Softwares are built to-day testing of web service have becomes crucial point. Web services are distributed, loosly coupled, autonomous, reusuable, discoverable, hides internal logic (Abstraction),minimize retaining information (Statelessness) and adhere to Service Level Aggrement (SLA).These inherent characterestics imposes great challenges to the tester.In this paper we try to impose hierarchical structure on Web Service Description Language(WSDL) in order to uncover more and more errors before its final deployment through blackbox testing.Our approach differes from others by imposing hierarchical structure on WSDL, finding various dependencies like data dependency, control dependency, and generation of Web Service Dependence Graph(WSDG) which are essential for testing.

Aplikasi komputer meningkat jumlahnya dan menjadi lebih kompleks seiring dengan pertumbuhan bisnis dan ilmu pengetahuan. Dalam hal ini, pengelolaan dan integrasi data menjadi sangat penting. Pengembangan Web Service semakin meningkat. Pengembang Web Service membutuhkan banyak data riset dan referensi mengenai kompleks atau tidaknya suatu Web Service berkaitan dengan perkiraan biaya pengembangan, batasan waktu pengerjaan, dan sumber daya yang dibutuhkan untuk pengembangan, termasuk spesifikasi komputer dan sumber daya manusianya. Setiap pengukuran yang dilakukan dibutuhkan tersedianya ukuran kuantitatif yang disebut metrik, yang selanjutnya akan menghasilkan output berupa kompleksitas dari Web Service. Atas dasar itu, diperlukan sebuah perangkat lunak yang dapat menghitung metrik skala dan kompleksitas Web Service dengan cara meng-import file bertipe xml document dan berisi dokumen WSDL (Web Service Description Language) yang digunakan untuk menggambarkan kompleksitas Web Service berdasarkan pengukuran Data Weight (DW) yang dihitung dari bobot Argument per Operation (APO) dan Operation per Service (OPS). Dari percobaan perhitungan kami secara manual terhadap suatu dokumen WSDL, dimunculkan beberapa hasil berupa banyaknya argumen, OPS, dan APO. Hal ini kami terapkan pada perangkat lunak dan menghasilkan proses perhitungan yang lebih cepat. Pengguna dapat meng-import document tipe .xml dan hasil kompleksitas Web Service akan dimunculkan dalam aplikasi. Ukuran metrik dan kompleksitas yang diperoleh dapat digunakan untuk memperkirakan manajemen pengembangan Web Service.

In modern manufacturing era, supply chains are increasingly becoming global and agile. To build agile global supply chains, companies first need to have access to a large supply base and secondly need an efficient mechanism for cost-effective and rapid location, evaluation, and selection of suppliers. This work introduces a matchmaking algorithm for connecting buyers and sellers of manufacturing services based on their semantic similarities in terms of manufacturing capabilities. The proposed matchmaking algorithm operates over Manufacturing Service Description Language (MSDL), an ontology for formal representation of manufacturing services. Since MSDL descriptions can be represented as directed labeled trees, a tree matching approach is implemented in this work.
