【摘要】：[目的/意義]網(wǎng)絡(luò)民族輿情監(jiān)測(cè)工作需要面對(duì)數(shù)據(jù)量龐大、現(xiàn)場(chǎng)數(shù)據(jù)復(fù)雜等問題。針對(duì)這些問題,提出了基于灰色關(guān)聯(lián)計(jì)算的網(wǎng)絡(luò)民族輿情監(jiān)測(cè)模型,給出了該模型的框架結(jié)構(gòu)與功能模塊,詳述了其處理流程與相關(guān)算法,通過仿真試驗(yàn)驗(yàn)證和分析了模型的效能。[方法/過程]該模型針對(duì)監(jiān)測(cè)系統(tǒng)的工作特點(diǎn),采用分布式結(jié)構(gòu)避免系統(tǒng)瓶頸,基于灰色關(guān)聯(lián)計(jì)算方法,實(shí)現(xiàn)監(jiān)測(cè)規(guī)則庫(kù)與現(xiàn)場(chǎng)數(shù)據(jù)的深度匹配,并進(jìn)行熱點(diǎn)事件的細(xì)節(jié)刻畫,最終實(shí)現(xiàn)網(wǎng)絡(luò)民族輿情熱點(diǎn)事件的預(yù)測(cè)和發(fā)現(xiàn)。[結(jié)果/結(jié)論]仿真試驗(yàn)結(jié)果證明,該模型具有較高的輿情監(jiān)測(cè)覆蓋度、較低的誤檢率和較高的服務(wù)器/終端處理性價(jià)比。
[Abstract]:[purpose / significance] the monitoring work of network national public opinion needs to face the problems of huge amount of data and complex field data. In view of these problems, a network national public opinion monitoring model based on grey correlation calculation is proposed. The frame structure and function module of the model are given, and its processing flow and related algorithms are described in detail. The effectiveness of the model is verified and analyzed by simulation experiments. [method / process] this model is aimed at the working characteristics of the monitoring system. The distributed structure is used to avoid the bottleneck of the system, and the depth matching between the monitoring rule base and the field data is realized based on the grey relational calculation method, and the details of the hot spot events are described in detail. Finally, the prediction and discovery of the hot events of network national public opinion are realized. [results / conclusions] the simulation results show that the model has higher coverage of public opinion monitoring, lower false detection rate and higher performance / price ratio of server / terminal processing.
