Abstract

The invention discloses a visual analysis method and system for the dynamic event evolution of social media. The method comprises the following steps that: aiming at certain event to extract a keywordfrom the social media, and obtaining social media data from the social media according to the keyword; according to a processing rule based on map metaphor, adopting a map mapping way to convert theinput social media data into an event evolution map E-Map, wherein the processing rule based on the map metaphor comprises cities, towns and rivers; and forming a structured projection space which contains semantics, and exploring the projection space through interaction by a user, wherein the social media data send to the processing rule at least comprises the following data: keywords, releasinginformation and retransmission information containing the keywords, and a user information spread behavior. By use of the method and the system, events in the social media can be subjected to visual analysis, and visualization can provide a high-level conclusion for event evolution for user, and also can enable the user to own ability for deeply exploring different aspects of data.

Description

technical field [0001] The invention relates to the technical field of event propagation analysis in social media, in particular to a method and system for visual analysis of social media dynamic event evolution. In particular, it refers to the visual analysis method and system of social media dynamic event evolution based on map metaphor. The event refers to a social event. The map-based metaphor is a map-based visual metaphor. Background technique [0002] Social events published and disseminated in social media (referred to as events), along with the dissemination of events (information diffusion), form an event evolution consisting of several stages, such as the beginning stage, middle stage, end stage, etc., in order to fully To understand and discuss the evolution of events, as well as the behavior of social media users (referred to as users) during the evolution of events (such as information dissemination behavior), we need to have the ability to analyze dynamic in...
