对会话语音的信息提取出现了许多挑战。我们描述的是找到语义上重要的名词短语的系统语法和语义。
Information extraction on conversational speech presents a number of challenges. The casual speaking style and lower “fact density” typical of spontaneous conversations make named entity extraction less effective than in other domains and leads us to consider extraction of descriptive noun phrases as a more powerful generalization of named entities. We describe a system for finding semantically important noun phrases that combines our conversational speech recognizer with a probabilistic model of syntax and semantics. We present preliminary experiments on a subset of the Switchboard corpus.
