能问问情感分析具体是以怎样的标准认定是否为水军的吗?比如正文的情感分析结果呈现出怎样的结果就认定其为水军?
没有固定标准,特殊情况特殊处理,有的分析只需要数值指标(关注数,粉丝数之类的),有的分析只需要文本,但是最终要怎么样,这是要慢慢摸出来的。
比如某套规则如果适用于微博用户群体,就不一定适用于twitter。对于微博来说,水军发言比较容易摸出套路,也经常会发些乱码(毕竟淘宝上卖的水军,几百家店都是共用估计十几个水军算法),所以只要好好思考好特定的输入结构(比如粉丝互动数就是不错的指标,文本就更不用说了但是要做好预处理),建立对应模型,然后测试集准确率高于70% 那么基本就可以理清思路了,然后慢慢修改输入结构和模型从而提升鲁棒性。反正水军发言和行为的套路越统一,准确率会越高,比如我这里就是怎么试都是90%以上。
