Embodiment Construction

[0035] A network service recommendation method based on the location of a mobile user, comprising the following steps:

[0036] (1) Establish a location-based preference model for mobile users

[0037] Taking time-position as the main line, extracting different network service sets caused by users changing with time-position in the training data, the steps of establishing the mobile user's location-based preference model are as follows:

[0038] ① For a mobile user ux, according to the two-tuple formula, extract the network service set Sx used by the user at a certain geographical location Lx, and obtain the network service feature P used by the user at this location L1 =(Lx, Sx), the two-tuple formula is P=(L, S), S is a multidimensional vector about the network service item used by the mobile user, and represents the network service used by the user at a certain location L;

[0039] ②At other different locations within this time period, perform Step ① to extract the network...

Abstract

The invention discloses a network service recommending method based on the positions of mobile users. Preference models are applied to the network service recommending process based on the positions of the mobile users, the similarity of the positions is introduced into the network service recommending selection process and is combined with credibility, and then the network service recommending method based on the positions of the mobile users is formed. By adopting the network service recommending method, the accuracy and the reliability of recommendation of network service are effectively improved, and meanwhile the problems of data sparsity and cold start in the recommending process are simultaneously relieved.

Description

technical field [0001] The invention belongs to the field of network methods, and more specifically, the invention relates to a network service recommendation method based on the location of a mobile user.
