Embodiment

[0070] Attached below image 3 and one The present invention will be described in further detail with the following examples, and it should be pointed out that the described embodiments are for the purpose of illustration only, rather than limiting the scope of the present invention.

[0071] Suppose a mobile phone user requests the latest news information from a media provider, and the news information contains two parts: video and text. An encode web service is a web service that encodes video and text, a compress web service is a web service that compresses an encoding for efficient transmission over a network, and a decode web service is a web service that decompresses and decodes compressed encoding. The following table is a description of the price and time consumption value of each candidate web service in the fictitious candidate web service set of the three web services.

[0072] Table 1. Initial candidate web service set and related attribute information

Abstract

The invention discloses a method for selecting web services guided by a user certainty degree in a Cloud environment. The method includes the following steps: (1) modeling according to requirements of a user, (2) carrying out discretization processing on a reference weight WA of the user, (3) filtering an available candidate web service set for the first time by means of non-numeric quality constraint, (4) processing data in the step (3) by means of a hierarchical iteration pairwise combination method, (5) processing a combination weight of each set in the step (2) to obtain a web service Comp Service List recommended for the user, (6) choosing a web service combination scheme by the user in the web service Comp Service List, and choosing the corresponding web service according to the web service combination scheme.

Description

technical field [0001] The invention discloses a web service selection method guided by user certainty in a cloud environment, relates to the technical fields of web service combination and computer software, and can be used for web service optimization selection. Background technique [0002] In the past few years, cloud computing (Cloud Computing) has developed rapidly and become more mature. Cloud computing is distributed computing (Distributed Computing), parallel computing (Parallel Computing), utility computing (Utility Computing), network storage (Network Storage Technologies), virtualization (Virtualization), load balancing (Load Balance) and other traditional computers and networks The product of the convergence of technological developments. According to Wikipedia's definition, cloud computing is a computing model that provides dynamically scalable virtualized resources in the form of web services through the Internet. Today, leading cloud providers like Amazon, ...
