Embodiment Construction

[0024] figure 1 It is a schematic flowchart of a method for recommending Web service combinations according to an embodiment of the present invention. Such as figure 1 As shown, the Web service composition recommendation method includes the following processes:

[0025] Step 101, obtaining the user's Web service composition requirements, the Web service composition requirements include at least two Web service function requirements;

[0026] Step 102, according to the at least two Web service functional requirements, determine a set of candidate services corresponding to each of the Web service functional requirements;

[0027] Step 103: Perform association rule analysis on the historical invocation service set, determine candidate Web services whose frequency index is greater than a preset standard in the candidate service set, and generate frequent services including candidate Web services whose frequency index is greater than a preset standard gather;

[0028] Step 104,...

Abstract

The invention provides a recommendation method and a device for Web service combinations. The method includes obtaining a Web service combination requirement of a user, wherein the Web service combination requirement comprises at least two Web service function requirements; determining candidate service combinations corresponding to each Web service function; performing association rules analysis on historically called service combinations, determining candidate Web service with a frequency index larger than that of a preset standard in the candidate service combinations, and generating a frequency service combination including the candidate Web service with the frequency index larger than that of the preset standard; performing service combination relation analysis on the Web service combinations to obtain at least two combination relations between the Web service combination requirements; and determining recommendation Web service corresponding to each Web service function requirement to form recommendation Web service combinations according to the frequency indexes of each candidate Web service in the frequency service combination and global quality of service (QoS) attribute which uses the candidate Web service on the basis of the combination relations.

Description

technical field [0001] The invention relates to Web service technology, in particular to a method and device for recommending a Web service combination, and belongs to the field of computer technology. Background technique [0002] In recent years, the rapid development of Web service technology and service-oriented software structure has provided an important foundation for the sharing and integration of heterogeneous information and platforms, and has become the key supporting technology and standard for the development of distributed application systems. important direction of research. Web service is a self-describing and self-contained software module that can be used through the network to complete tasks, solve problems, or handle transactions on behalf of users and application processes under the infrastructure of distributed computing, so it is increasingly used on the Internet information exchange. Web service is an extension of traditional component technology in...
