Credit scoring is an important process in every financial institution and bank. Its high accuracy in classifying customers helps decrease the credit risk and increase reliability and profit. In this paper, we propose a binary classification approach that can classify customers who apply for loans. A statistical technique called Stepwise Regression (SR) is used as a pre-process to select important...
Data-intensive systems in e-governance collect and process data to ensure conformance to a set of business rules. Testers meticulously verify data in test databases, extracted from different steps of a live production stream , for correct application of business rules. We simplify the process by allowing testers to model a test domain on a relational database and automatically generate test cases...
Data mining is to extract the potentially useful knowledge and information from large amounts of data. How to dig up effective, reliable, understandable, and interesting association rules from vast amounts of information to help people make decisions has become an urgent problem to be solved. People want to use a reasonable evaluation method to measure reliability or validity of association rules,...
In this article we present our first approach in using Passive Testing (used in protocol and software conformance checking) and Process Mining (used in enterprise workflow analysis) techniques for analyzing DNS operation traces.
Ranking areas by popularity of a business category is an essential problem for business planning. Traditional approaches rely on economic and demographic factors nearby. However, the acquisition of relevant data is usually expensive. In this paper we propose a novel approach to address this problem by exploiting user-generated contents from location based social networks, which are cheap, fine-grained,...
with the development of supply chain and logistic, the commodity classification and amount provided by E-commerce system rise increasingly. The traditional web-centered searching commerce model has become the bottleneck hindering value-adding of e-commerce enterprises, while personalized e-commerce system is one effective way to solve this problem. Incorporating the demand for personalized e-commerce...
Web services technology provides a flexible and cost-effective paradigm to construct highly dynamic systems through service discovery, composition, and ultra-late binding. However, its new features bring great pressure to maintain Web service-based system. Based on the massive testing results, how to locate the fault points in system is a challenging task. In the paper, a two level diagnosis framework...
Requirements engineering and testing offer two complementary views of system development, and can, therefore, benefit from each other. This paper describes the lessons Metso learned from jointly improving requirements and testing processes. The goal of the process improvement was to increase the quality of R&D work. The new requirements and testing processes were piloted in an R&D project...
Recently with the rapid growth of network and changes of business environment, the enterprises require the integration of various information systems and their interoperation. The SOA (service oriented architecture) based on Web services is widely used for integration of these information systems. And as the standard integration language for the business processes, BPEL (business process execution...
Framework technology, as an important approach to develop new generation network application provides various and flexible design models for professionals. Based on open source framework this paper presents a solution on the construction and testing for the new generation network application. This solution shows a high quality software platform (Struts+Spring+Hibernate) and reveals the testing strategies...
Web services can be combined in a collaborative way to create a new Web services system (WSS) to solve more complex problems. However, WSS testing is not a trivial task, features like distribution, loose-coupling, and collaboration bring great pressure to the latter testing activity. In the paper, a hierarchical testing and evaluation strategy is proposed from the perspective of the developers of...
Firm technological capability definitely has great significance on firm upgrading. This paper investigated the relationship between firm technological capability and firm upgrading based on 717 valid samples. The results show that technological shifting capability in firm technological capabilities is significantly positively associated with product upgrading while technological operating capability...
Business processes based in WS-BPEL compositions are rapidly becoming commonplace in recent years, so it is important to pay special attention to testing in this context. Mutation testing is a white-box testing technique that has been applied successfully to programs written in several languages. In order to apply it we need a system for mutant generation. This paper presents the first results of...
We describe a framework and methodology for managing the privacy policy of an enterprise, including creation (based on factors like legislation and consumer preferences), validation and verification, deployment and enforcement, and compliance testing for business processes and software. To evaluate this approach, one module of our framework (compliance testing) is implemented for an existing prominent...
In the last several years, the concept of a design decision has become important in the software architecture design community. A design decision begins with an issue and then focuses on the alternative solutions and the rationale for these solutions. The question of where the issues come from is not usually addressed within this approach. In this paper, we present a “generate and test” approach to...
For large and complex composite Web services which are composed by BPEL and a set of WSDL and XSD documents, we urgently need the aid of the tools in designing and selecting test cases. However, most of mature testing tools which generate test data with the information of WSDL are used for single service while the research for composition remains in the realm of theory. So we apply the theory of data-flow...
This paper describes a model for capturing service designs and the design of service product lines. The model promotes reuse of service artifacts, enables a balanced view of the service from different stakeholder viewpoints, and provides a foundation for design for service quality. The model leverages a phased approach to design, engineering and management of services. The model has applicability...
Digital rights management (DRM) systems provide a means for content providers and distributors to address the unauthorized copying issue, in order to meet consumer's expectations, DRM approaches and related services and applications upon which they are based should coexist in an environment that supports interoperability. In this paper, we propose a General-Schema (G-Schema) approach to DRM interoperability...
The success of service-oriented architectures (SOA) depends on faultless and seamless service integration. Formal modeling of global communication protocols between services enables a model-based integration testing (MBIT) approach. In this paper we present an MBIT approach based on SAP proprietary choreography models called message choreography models (MCM). We explain how MBIT fits into the SAP...
Quality testing always plays an important role in product manufacturing. However, for various products often needing different testing processes, current quality test systems have not provided adequate support for their flexibility and adaptability yet. For the purpose of improving their dynamic performance, the conceptions of workflow management system (WfMS) is adopted into the development of quality...
