Performance Improvement Strategy in Online New Event Detection System
Naijing Hu · Jisuanji gongcheng · 2008
The existing studies focus a lot on the detection accuracy without considering efficiency,which leads a low performance in practical Online New Event Detection(ONED) domain.This paper analyzes the traditional ONED systems about the low performance limitation,and proposes an improved framework.A lot of storage and calculation overhead can be degraded based on the techniques of setting reasonable parameters and pre-filtering index linking tables,without decreasing detection accuracy.Experimental results demonstrate the enhanced performance of the ONED system.
