Embodiment Construction

[0121] Using steps 1-4 of the present invention, a researcher's social network is created, and experts in a certain field are found in the social network to verify the invention of this paper. All experiments of the present invention are realized by Java programming, and run on servers configured as dual-core Intel Xeon 3.0GHz processors and 2GB internal memory.

[0122] (1) Modeling of researchers' social network

[0123] At present, the construction of our researchers' social network mainly includes two parts of information: each researcher has his own personal description information (including position, unit, research interest, paper title and corresponding conference published); There is a "same author" relationship, that is, when two people have published an article together, they will establish a "same author" relationship.

[0124] (2) Generation of researchers' social network

[0125] Through the data analysis of a specific academic paper website (http: / / www.informa...

Abstract

The method comprises: establishing a society relation network graph by using society relation network generation server; said graph is described by using personal description information, human relation, relation type and the mapping function between human relation and relation type; the expert value calculation server reads the information from the database server, and according to the weighting, analyzes the correlation between the key word, the person description information and the thesis information to get a initiative expert value; then according to the importance and osculation of human relation, constructs a propagator matrix; according to the initiative expert value and the propagator matrix, makes iteration to get the expert value of all experts; after normalization, arranging it in descending order; outputs it to the Web server to provide the option for user.

Description

technical field [0001] The invention belongs to the field of social network information processing, in particular to social network search under the Internet. Background technique [0002] With the rapid development of the Internet and the transition from Web1.0 to Web2.0, social networking has gradually become a very important Web application. For example, we can use social networks to find jobs, find employees, find friends with common interests, and find business partners. [0003] Web-based social networks provide us with a large number of data sources, which are helpful for some data mining and knowledge discovery on this basis. These researches have great challenges in the Web2.0 era. For example, trust chain mining, personalized recommendation and expert discovery, etc. [0004] The goal of expert information processing is to automatically discover experts with knowledge in a specific domain. By finding experts, we can quickly get answers to some professional quest...
