—This paper introduces a reliability model, and a reliability analysis technique for component-based software. The technique is named Scenario-Based Reliability Analysis (SBRA). Using scenarios of component interactions, we construct a prob-abilistic model named Component-Dependency Graph (CDG). Based on CDG, a reliability analysis algorithm is developed to(More)
Relevance Feedback (RF) is an important technique to improve information retrieval and has emerged as one of the hottest topics for both the industry and academic researchers. The performance of RF depends on feedback information. As the volume of feedback information gradually increases, Explicit Relevance Feedback (ERF) is attractive. In this paper, we(More)
When the stock market has become more and more competitive, the stock market prediction has been a hot research topic. Traditional methods are based on historical stock data, which ignore the latest market information. Later although financial news is proposed to access market information, there are some disadvantages for news to predict the stock market.(More)
Currently many research show that, in a sophisticated application system, the faults which are impossible to occur theoretically, may take place in practice. J2EE (Java 2 Platform, Enterprise Edition) distributed environment has been popularly applied to EAI (enterprise application integration). With the growth of the numbers of Jsp, Servlet and EJB(More)
We propose an approach of component-based software reliability analysis which includes the benefits of both time domain, and structure based approaches. This approach overcomes the deficiency of existing black box and white box techniques that fall short of addressing repair, and internal system structures simultaneously. Our solution adopts a method of(More)
—With the growing size and complexity of software applications, research in the area of component software reliability analysis has gained prominence. To ensure analytical tractability, traditional approaches usually ignore fault correction process of component software based on simplifying assumptions of instantaneous and perfect debugging. As a result,(More)
—We develop an approach of component software reliability analysis which includes the benefits of both time domain, and structure based approaches. This approach overcomes the deficiency of existing NHPP techniques that fall short of addressing repair, and internal system structures simultaneously. Our solution adopts a method of transformation of testing(More)
