Embodiment Construction

[0017] In step 1, the present invention constructs the source group G through two steps s to target group G g The information dissemination process model of:

[0018] Step 1.1: First construct the information dissemination process model

[0019] Step 1.1.1: Get G s and G g The two groups G with the highest reliability 1 and G 2 . For a specific group G, use the following formula to obtain its credibility c[G]:

[0020] c[G]=ln∑ u∈G e r(u)+b(u) ,

[0021] Where ln is the natural logarithm, e is the base of the natural logarithm, r(u) is the objective credibility of user u in Weibo, b(u) is G s and G g The average subjective trust degree of user u, expressed as:

[0022]

[0023] where b(su,u) is G s In the subjective trust degree of user su to u, b(gu,u) is G g The subjective trust degree of user gu in u, |G s |and|G g |represents G s and G g The number of users in .

[0024] Step 1.1.2: Put G s , G g , G 1 and G 2 Four groups form a weighted directed ...

Abstract

The invention discloses a method for generating an information spreading path with global minimum cost between microblog groups. The method mainly comprises three steps of path cost modelling, initial path generation and deep path optimization, wherein formal representation of the information spreading path between the groups and construction of a time cost model of the information spreading path are realized in the step 1; an information spreading path with local minimum cost between the groups is generated in the step 2; and the information spreading path with the global minimum cost is finally generated and output through iterative optimization of crossover and mutation operators in the step 3. Compared with the prior art, the method has the advantages of high accuracy, fast speed, strong extendibility, simplicity and easiness in implementation and can be applied to the fields, such as public opinion monitoring, data visualization, electronic commerce, intelligent transportation and medical treatment and health.

Description

technical field [0001] The invention relates to the technical field of big data information services in cyberspace, in particular to a method for generating an information propagation path with a global minimum cost among microblog groups. Background technique [0002] Entering the era of Web 2.0, the rise of social networking systems dominated by Weibo provides an important platform for people to analyze information and exchange opinions with a high degree of freedom. With the help of information sharing, dissemination and acquisition technology based on user micro-blog relationship, users can form different communities through WEB, WAP and various clients, thus gaining a greater degree and scale than traditional print media and network media. information, and at the same time generate a richer interactive communication experience and enhance the user's actual use experience. It is precisely because of the unique fission information dissemination and sharing mode generated...
