各位前辈，想请教一下关于自建小型语料库的问题，我想知道如果语料来自工科论文，正文中有较多希腊字母，及一些公式表达，这些应该怎么处理呢？如果将其删除的话，又会影响一个句子的完整性，这样会不会影响到赋码，然后进行句法分析呢？
比如说这样的句子：Letting αi(·)=log(|Hi(·)), it can be shown that a generalization of (4) with a real two-tone stimulus is expressed as (5) where p=m+n|, and k1 and k2 represent the frequencies of the two different tones, with k1,k2>0.
如果是做被动语态分析，该怎样处理呢？
