2020年春節(jié)悬赏，冠狀病毒在中國(guó)的蔓延不容忽視树肃，大大小小的新聞媒體相繼進(jìn)行報(bào)道蒸矛。太多的消息讓人越看越煩躁，不如通過(guò)詞云進(jìn)行關(guān)鍵字的整理，幫著梳理下疫情的脈絡(luò)雏掠。
1斩祭、在各大新聞平臺(tái)中，copy下20余篇相關(guān)新聞到本地作為數(shù)據(jù)源乡话；
2摧玫、通過(guò)kumo的詞云功能生成詞云（基于JAVA開(kāi)發(fā)）；
3绑青、對(duì)詞云結(jié)果進(jìn)行分析诬像；

詞云結(jié)果
news.png
通過(guò)詞云結(jié)果分析，字體越大代表關(guān)鍵字命中率越高掠拳。在這些信息里癞揉，摘取自己關(guān)注的關(guān)鍵字纸肉，再通過(guò)谷歌溺欧、度娘查詢(xún)具體的內(nèi)容，也不至于像一只沒(méi)頭蒼蠅一樣柏肪，看著林林總總的信息越看越恐慌姐刁。
PS：數(shù)據(jù)源一定是越多，命中的結(jié)果越準(zhǔn)確烦味，感興趣的同學(xué)可以自行copy或者通過(guò)爬蟲(chóng)來(lái)爬取相關(guān)信息聂使，得到自己想要的結(jié)果。
感興趣的同學(xué)記得點(diǎn)贊哦~
