Abstract

Hierarchical lexicon structures are not only of great importance for the nonredundant representation of lexical information, they may also contribute to the efficiency of the actual processing of natural language. Two parsing techniques that render the parsing process efficient are presented. Windowing is a technique for incrementally accessing the hierarchical lexicon. Lexical preferencing implements preferences within the parsing process as a natural consequence of the hierarchical structure of the lexicon. Within a proof-theoretic approach to Categorial Grammar it is possible to implement these techniques in a formal and principled way. Special attention is paid to idiomatic expressions.

增量处理和分层词典
分层词汇结构不仅对词汇信息的无冗余表示具有重要意义,而且有助于提高自然语言实际处理的效率。提出了两种解析技术,以提高解析过程的效率。窗口化是一种增量访问分层词典的技术。词法首选项在解析过程中实现首选项,这是词法层次结构的自然结果。在范畴语法的证明理论方法中,有可能以形式化和原则性的方式实现这些技术。特别注意习语表达。
