摘要

提出了一种基于LIFE编程语言的具有类型层次结构的多重非单调继承网络，用于统一范畴语法(UCG)指定大型复杂词汇。继承被定义为一种演绎的统一过程，它会逐步地细化类。带泛化的析取解释为非单调继承可能引起的矛盾提供了一种实用的解决方法。将UCG类别转换为增强的与上下文无关的词法规则，可以更自然地表示UCG并提供高效的解析算法。

Parsing unification categorial grammar with object-oriented knowledge

A multiple nonmonotonic inheritance network with type hierarchies based on the LIFE programming language is proposed for Unification Categorial Grammar (UCG) to specify a large and complex lexicon. Inheritance is defined as a deductive unification process that incrementally refines classes. The disjunctive interpretation with generalization provides a practical solution to the potential contradictions caused by nonmonotonic inheritance. The transformation of UCG categories into augmented context-free lexical rules leads to a more natural representation of UCG and an efficient parsing algorithm.<>
