User mining method and device in event propagation process

Abstract

The invention discloses a user mining method and device in an event propagation process, which can be used for mining important users during a hot event propagation process. The method includes: configuring an aimed hot event; establishing a keyword associated with the hot event according to the hot event; crawling information data including the keyword from a webpage information database according to the keyword; and saving the crawled information data in a local database corresponding to the hot event. In this way, the local database can be established from the webpage information database according to the hot event, the local database can establish a directed forward network, and an undirected forward network can be obtained through undirected treatment of the network; and the established undirected forward network is selected according to a certain hot event, and then the important users of hot event propagation can be determined through an importance sequence of nodes.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a user mining method and device in the process of event propagation. Background technique [0002] The development of social networks has a great impact on human life. Whether it is making friends, working or shopping, people have become accustomed to relying on social networks to obtain information. Users with high influence can be used as sources of information dissemination in social networks to promote the dissemination of effective information on social networks. In order to allow information to spread faster and wider in the network, the key is to find nodes with spreading influence. Due to the huge number of total users in the network, the complex network structure, and the extremely limited propagation capabilities of most nodes in the network, finding users with high propagation influence has always been a major challenge. [0003] With the rapid development of socia...

[0004] The existing important node mining methods are to find influential users in the network that users care about, but in a specific hot event, the important node that plays a greater role in promoting the spread of the hot event is not necessarily the Those users who are more influential on the network, the existing important node mining methods are based on the entire network structure to mine influential users, not for a specific event, the existing important node mining methods can only Find the influential nodes in the attention network macroscopically, but cannot find the important nodes in the propagation process of a specific event

For example, suppose an important node in the network is a certain big V Weibo account. Although it is a very influential user, it may If A is released or reposted, then the big V Weibo account is not an important node in the propagation process of event A, so it is impossible to determine the important node in the propagation process of event A
