Summary
This study introduces a new method for verifying web service quality of service (QoS) data. It uses objective measurements to calculate service reputation, aiding consumer selection.
Area of Science:
- Computer Science
- Software Engineering
- Distributed Systems
Background:
- Early web service transactions lacked credible quality of service (QoS) information.
- Service providers often published unverifiable QoS data, hindering trust.
Purpose of the Study:
- To develop a trustworthy method for evaluating web service reputation based on factual QoS data.
- To provide consumers with reliable references for selecting web services.
Main Methods:
- Collected factual QoS running data using a WS-QoS measurement tool.
- Developed an algorithm to compare offered versus measured QoS data, calculating similarity.
- Implemented a reputation evaluation method based on data similarity.
Main Results:
- The approach demonstrated feasibility through implementation and experiments with three web services.
- The calculated reputation values serve as effective references for service consumers.
Conclusions:
- The proposed method offers a reliable way to assess web service reputation.
- Objective QoS data and reputation evaluation enhance consumer decision-making in service selection.

01:19Quality Assurance
4.0K
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

01:19Quality of Water

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

01:29Self-Evaluation Maintenance Model
419
The Self-Evaluation Maintenance (SEM) model offers a psychological framework to understand how individuals’ self-esteem is influenced by the achievements of others, particularly those with whom they share close personal bonds. The SEM model operates when personal rather than social identity guides individuals. Central to this model is the notion that individuals have an inherent desire to preserve a favorable self-image, which is continuously shaped by interpersonal comparisons and...

01:05Quality Control
4.2K
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

01:17Pulse amplitude and quality
3.6K
Pulse amplitude is a crucial indicator of cardiac health because it provides valuable insights into the strength of left ventricular contractions and the overall uniformity of blood circulation within the vasculature. The strength of the pulse is directly related to the force with which the heart contracts and the volume of blood being pumped.
A weak or absent pulse may indicate reduced cardiac output or poor left ventricular contraction, which can be signs of cardiovascular dysfunction or...

9.1K
The confidence coefficient is also known as the confidence level or degree of confidence. It is the percent expression for the probability, 1-α, that the confidence interval contains the true population parameter assuming that the confidence interval is obtained after sufficient unbiased sampling; for example, if the CL = 90%, then in 90 out of 100 samples the interval estimate will enclose the true population parameter. Here α is the area under the curve, distributed equally under...
