Hierarchical Topic Detection and Tracking and Implementation of System
Wei Cheng · Journal of Guangxi Normal University · 2007
Since 1996,topic detection and tracking has obtained extensive attention and has encountered great challenge when making great progress.By analyzing mass data,the differences between hierarchical topic and hierarchical clustering are firstly proposed,which should be decided by the construction of event and be represented as three layers,for hierarchical topic produced by computer automatically has external relation with the real world.Then an algorithm for hierarchical topic detection and tracking that can process large-scale data are proposed and implemented on our clusters computer.
