句类中E块的作用及其判定策略

The Effect of E-Chunk on SC and Its Determinant

1 引言在一个句子中,谓语起着极其重要的作用。多年来,无论是以句法分析为主的自然语言处理,还是以语义分析为主的自然语言理解,都把对谓语的确定作为句子分析的关键因素。首先,从句子的构成形式上看, 可以通过谓语的类型,判断句子是无宾语,单宾语,还是双宾语,甚至是小句作宾语;其次,从意义上看,又可以通过它得到句子的主语和宾语所具备的基本语义信息,是人还是物,是具体概念还是抽象概念,或者,从格的角度讲,是施事格还是受事格等。HNC理论同样肯定谓语所起的作用,同时认为,一方面“谓语”的内涵过泛,另一方面对谓语的复合构成缺乏深层的揭示。为此,它引入了表示特征的E(igen)语义块基元的概念, 由它构成特征语义块EK。

Sentences Analysis in HNC theory is called Semantics Analysis of Sentences Category (SASC),by which,the Sentence Category (SO will be determined at first,and the type of Semantic Chunks will be obtained and their inner constitutes are analyzed based on SC. E(igen) Semantic Chunk is very important for SCAS. It is similar to traditional predicate formally,but there exist differences between them in meaning. In this paper,well state main idea of SASC by analyzing features and constitutes of E-chunk.
