Abstract

The present application discloses a method and device for generating an event group evolution diagram, which solves the technical problem of high time complexity in running an algorithm for configuring an event evolution diagram. The specific disclosed methods include: obtaining an event evolution graph, which represents the corresponding relationship between the duration of an event and the popularity of attention; obtaining the available area not occupied by other event evolution graphs in the candidate area corresponding to the duration according to the line segment tree ; Configure event evolution graphs in available regions to generate event group evolution graphs. The present application reduces the time complexity of running algorithms for configuring event evolution graphs.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and a device for generating an event group evolution diagram. Background technique [0002] At present, in the industry, a line graph is used to graphically display the evolution process of an event group. figure 1 A schematic illustration of a line graph in the prior art is shown. Such as figure 1 As shown, the horizontal axis of the line chart can represent time, and the vertical axis can represent the heat of attention to the event. Polylines of different colors represent different types of events, and the number of events of corresponding types corresponding to corresponding time points can be displayed at the inflection points of the polylines. exist figure 1 In , polylines of different thicknesses are used to represent polylines of different colors. [0003] In academia, bubble diagrams are used to graphically display the evolution process of...
