+\parinterval  回顾一下{\chaptertwo}的内容，语言建模的问题被定义为：对于一个词序列$ w_1w_2\dots w_m$，如何计算该词序列的可能性？词序列出现的概率可以通过链式法则得到，如公式\eqref{eq:9-57}所示：
 \begin{eqnarray}
 \funp{P}(w_1w_2\dots w_m)&=&\funp{P}(w_1)\funp{P}(w_2|w_1)\funp{P}(w_3|w_1w_2)\dots \funp{P}(w_m|w_1\dots w_{m-1})
 \label{eq:9-57}
 \end{eqnarray}
-\parinterval  由于$ \funp{P}(w_m|w_1\dots w_{m-1}) $需要建模$ m-1 $个词构成的历史信息，这个模型仍然很复杂。于是就有了基于局部历史的$n$-gram语言模型，如公式\eqref{eq:9-58}：

 \parinterval  目前，词嵌入已经成为诸多自然语言处理系统的标配，也衍生出很多有趣的研究法方向。但是，冷静地看，词嵌入依旧存在一些问题：每个词都对应唯一的向量表示，那么对于一词多义现象，词义需要通过上下文进行区分，这时使用简单的词嵌入式是无法处理的。有一个著名的例子：
 \begin{example}
-Jobs was the CEO of {\red{\underline{apple}}}.
+Aaron is an employee of {\red{\underline{apple}}}.
 \hspace{2em} He finally ate the {\red{\underline{apple}}}.
