As an important method for creating value-added services by composing existing services, Web service composition technology has attracted an increasing attention in recent years. Most current service composition and optimization methods utilize quality of service (QoS) attributes to decide which concrete services to invoke. However, trust which is of(More)
Changes to a composite service need to be well analyzed in order to ensure the trust of it. The analysis can be driven by identifying the impact caused by the changes on the trust of other component services as well as the composite service. In this paper, we propose a trust impact analysis model to analyze the impact of two kinds of evolution operations(More)
The performance of commercial websites is a critical issue that has a significant effect on consumers' online decision-making. This study develops and applies a fuzzy model to assess the performance of hotel websites. It presents a fuzzy decision-making approach to the evaluation of tourism website performance that integrates consumer perceptions with a(More)
Several studies have shown that soil microorganisms play a key role in the success of plant invasion. Thus, ecologists have become increasingly interested in understanding the ecological effects of biological invasion on soil microbial communities given continuing increase in the effects of invasive plants on native ecosystems. This paper aims to provide a(More)
Composite services implement value-added functionality by composing service components with smaller granularity. Trust is an important criterion to judge whether a composite service can behave as expected. A feasible trust evaluation method for composite services is needed, which can guide service selection for users and the trust-based optimization and(More)
—Previous studies on hotel website performance have relied on frequency counting, content analysis or user behavioral approaches [1]. These studies cannot accurately calculate hotel website performance in terms of user assessments of dimension/ attribute weighting and performance ratings. The aim of this research is to develop a scientific model that(More)
This study was performed to evaluate the effect of concomitant supplementation of genistein and silicon on bone mineral density and bone metabolism-related markers in ovariectomized rat. Three-month-old Sprague Dawley female rats were subjected to bilateral ovariectomy (OVX) or sham surgery, and then the OVX rats were randomly divided into four groups:(More)
