Problems solved by technology

[0009] (1) The subjective preference of the user and the objective characteristics of the QoS attribute data of the Web service are not considered comprehensively, and the QoS is mainly measured based on the subjective preference of the user, resulting in one-sidedness of the measurement results
[0010] (2) The different roles of each QoS attribute in QoS measurement cannot be reasonably explained, that is, the importance or irreplaceability of each QoS attribute cannot be explained from the perspective of practical significance, so the rationality of the measurement results cannot be guaranteed
However, the existing methods all have various deficiencies in the accuracy of QoS measurement

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0035] The present invention comprehensively considers the service quality QoS measurement method of the Web business of subjective and objective weight, is to divide the QoS factor of Web business into subjective and objective two kinds: Subjective QoS represents the degree that Web business conforms to user preference, and objective QoS represents the overall performance of Web business Among them, subjective QoS uses subjective weights to quantify the ambiguity of user preferences on the basis of dividing user preference levels, so as to accurately grasp users' subjective needs; objective QoS uses Objective weights are used to correct the one-sidedness of user preferences, so that the QoS measurement results can accurately reflect the overall performance of Web ...

Abstract

Provided is a measurement method of Web QoS through overall consideration of the subjective weight and the objective weight. According to the measurement method, QoS factors of Web services are divided to be subjective factors and the objective factors, wherein the subjective QoS shows the degree of the Web services to meet user preference, and the objective QoS shows the overall performance of the Web services. According to the subjective QoS, on the basis of dividing the levels of the user preference, the subjective weight is adopted to quantize the fuzziness of the user preference so that the subjective requirement of users can be mastered accurately. According to the objective QoS, on the basis of analyzing the data features of QoS properties of the Web services, the objective weight is adopted to correct the one-sidedness of the user preference so that a QoS measurement result can accurately reflect the overall performance of the Web services. Through the overall consideration of the subjective QoS and the objective QoS of the Web services, the accurate QoS measurement result is obtained. The method takes the user subjective preference and the objective features of the QoS data into overall consideration, so that not only is user preference met, but also the overall performance of the Web services is mastered accurately, the accurate QoS measurement is carried out, and the method provides important reference factors for reasonably selecting the Web services and makes a contribution to popularizing the application of the Web services.

Description

technical field [0001] The invention relates to a method for measuring Web business service quality QoS (Quality of Service) with comprehensive consideration of subjective and objective weights, and belongs to the technical field of computer applications. Background technique [0002] Because there are a large number of Web services in the current network, when selecting a Web service, users need to face more and more candidate Web services with the same function but different performance. How to choose the most suitable Web service to meet the user's service quality QoS requirements is the key to successfully constructing Web-oriented service applications. The specific embodiment of QoS requirements is a set of QoS attributes, each of which is used to represent the quality information of a certain aspect of Web services. [0003] Common Web service QoS attributes include: availability, response time, bandwidth and throughput, and so on. Since there are a large number of c...
