面向中间语义表示格式的汉语口语解析方法

口语解析在人机对话系统和口语翻译系统中的作用是十分关键的。本文提出了一种统计和规则相结合的汉语口语解析方法,解析结果是一种中间语义表示格式。该方法分为两个阶段。首先,采用统计方法,解析出输入句子的语义信息,然后,利用规则,将这些语义信息映射到中间语义表示格式。试验证明,此方法具有较强的鲁棒性,而且避免了完全用规则方法解析的一些弊端,达到较高的解析正确率。

Chinese Spoken Language Analyzing Facing the Middle Semantic Representation

Spoken language analyzing is a crucial part in human-machine dialog system and spoken language translation system.In this paper we present a Chinese spoken language analyzing method based on the combination of statistical and rule methods The analyzing result is a middle semantic representation.It has two stages,first,use the statistical method to analyzing the semantic information,then use the rule method to map the semantic information to the middle semantic representation.This method avoids the shortcoming of the rule and has high robustness,at the same time it achieves a lower error rate.
