Embodiment Construction

[0056]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 through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] In traditional social networks, features such as user friendships and user interaction records can be used to measure the closeness of relationships between users, while the dimension of geographic information is added to mobile social networks. For example, users can add friends based on geographic location, add geographic tags when sharing text, share their travel trajectories, and share pictures and videos with latitude and longitude information. Therefore, through the mobile social network, not only the information that can be obtained in the traditional social network such a...

Abstract

The present invention provides a method for determining user relationship strength in a social network. The method comprises: acquiring data associated with user geographic information and user interaction from a mobile social network, extracting characteristics characterizing user geographic preference similarity, user mobility similarity and user interaction strength from the data, taking each characteristic as an observable variable, taking the user geographic preference similarity, the user mobility similarity and the user interaction strength as non-observable variables, and determining the user relationship strength by use of a structural equation model. The method gives full consideration to the relationship among factors that influence the user relationship strength in an actual social network, so that the user relationship strength can be weighed more effectively in a more detailed manner.

Description

technical field [0001] The invention relates to social network and data mining, and in particular to a method for measuring relationship strength of social network users. Background technique [0002] Social networking applications such as Wikipedia, Facebook and Twitter have achieved great success in recent years and have gradually changed people's work and lifestyle. At the same time, intelligent terminals such as smart phones and tablet computers are becoming more and more popular. More and more people start to use location-based services (LBS, Location-Based Service), such as positioning, location sharing, etc., and a large amount of GPS information is uploaded and shared. While recording the user's movement history, these location information can also reflect the user's interest, preference and mutual relationship to a certain extent. For this reason, location-based calculation of user relationship strength, as a research hotspot in computer applications, has received...
