Problems solved by technology

But this kind of method is to calculate a global reputation value, that is to say, the reputation value reflected by the same service for different users is the same, which does not reflect the personalized needs of users

Embodiment Construction

[0036] In order to describe the present invention more specifically, the service recommendation method of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] like figure 1 As shown, a service recommendation method based on network modeling includes the following steps:

[0038] (1) Establish a trust relationship network T-Net.

[0039] Construct the trust relationship network T-Net according to the user's evaluation relationship on the service, and obtain the user's feedback evaluation value on the service; for example figure 2 As shown, T-Net is composed of multiple users and multiple services. For any user in T-Net, the evaluated services are connected to the user through network cables;

[0040] (2) Split T-Net into user network U-Net and service network S-Net.

[0041] like image 3 As shown, U-Net includes all users in T-Net, and users who have evaluated the same service are connecte...

Abstract

The invention discloses a network modeling-based service recommending method which comprises the following steps of: (1) establishing a trust relation network T-Net; (2) splitting the T-Net into a user network U-Net and a service network S-Net; (3) calculating the similarity of users of the U-Net and the similarity of services of the S-Net; and (4) establishing a service set to be recommended for the users, calculating a comprehensive credibility of the services in the set, ordering the services and further recommending the services to the users. According to the method, by carrying out network modeling on the evaluation relation between users and services and analyzing and excavating the similarity of the users and the similarity of the services, the individual preference of the users to the services can be analyzed through the calculation on the similarity, thereby calculating individual credibility aiming at different users, and furthermore recommending individual trust services for the users, so that the recommended services are more close to practical demands of the users, and the efficiency and accuracy in recommendation are improved.

Description

technical field [0001] The invention belongs to the technical field of network services, and in particular relates to a service recommendation method based on network modeling. Background technique [0002] Web service is a specific manifestation and functional carrier of the service concept emphasized in service computing. It is an application program based on the Web environment that is self-adaptive, self-describing, modular and has good interoperability. As a new distributed component model, Web service has played an increasingly important role in e-commerce, enterprise application integration and other fields. With the large-scale growth of the number and types of Web services in the Internet, how to recommend the most suitable and high-quality services to users conveniently and effectively has gradually become one of the key issues to be solved by SOA (Service Oriented Architecture). [0003] In recent years, scholars at home and abroad have proposed Web service recom...
