Method and system for establishing interpersonal relationship model of suspect

Abstract

In particular, the invention relates to a method and system for establishing an interpersonal relationship model of a suspect. The method comprises the steps of defining the number of layers of an interpersonal relationship model and the node type of nodes at each layer; obtaining and saving client data of a suspect as a data file of a preset format; according to the data file and the node type of each layer, determining the number of nodes per layer, node data corresponding to each node and relation attributes of the relevant nodes on the adjacent two layers; and establishing the interpersonal relationship model according to the number of nodes, the node data of each node and the relational attributes of the relevant nodes. The method of the invention can collect and analyze client data such as data of certain types like call record of the suspect's mobile phone, short messages, an address book, instant chat software (QQ, WeChat, Momo, etc.) and so forth, and generate a relationship diagram between the suspect and others. The modeling method is highly efficient, the generated interpersonal relationship diagram is simple and direct, and investigators are assisted in analyzing and solving a case.

Description

technical field [0001] The invention relates to the field of data collection, in particular to a method and system for establishing a suspect interpersonal relationship model. Background technique [0002] The character relationship model is widely used in the Internet industry, such as Renren, Facebook and other social networks, which can intuitively express the friendship relationship between people through graphs (including points and edges). However, the method for establishing a character relationship model in the prior art cannot be directly applied to the establishment of a criminal suspect's interpersonal relationship model in the field of case investigation and crime, mainly including the following problems: [0003] (1) The data sources are different. The data of social tools such as Renren.com are uploaded by users actively, while the criminal suspects need to be obtained by investigators. [0004] (2) The complexity of the relationship network is different, ther...

Problems solved by technology

[0004] (2) The complexity of the relationship network is different, there are many sources of social data, and the time span is large, which will lead to a huge relationship network. However, the data sources of criminal suspects are targeted, and generally only need to obtain mobile phone communication, IM chat, etc. Data, so the amount of data is different and the purpose of establishing the relationship model is different

[0005] (3) The efficiency of establishing a character relationship model in the existing technology is low, and it is difficult to generate the interpersonal relationship results of criminal suspects in a short time
