Abstract

This paper describes a unification-based lexicon system for NLP applications that incorporates mechanisms for multiple default inheritance. Such systems are intractable in the general case---the approach adopted here places a number of restrictions on the inheritance hierarchy in order to remove some of the sources of complexity while retaining more desirable properties. Implications of the design choices are discussed, comparisons are drawn with related work in computational linguistics and AI, and illustrative examples from the lexicons of German and English are given.

基于统一的词典多重默认继承的实用方法
本文描述了一个基于统一的NLP应用词典系统,该系统包含多个默认继承机制。这样的系统在一般情况下是难以处理的——这里采用的方法对继承层次结构施加了许多限制,以便在保留更理想的属性的同时消除一些复杂性的来源。讨论了设计选择的含义,与计算语言学和人工智能的相关工作进行了比较,并给出了德语和英语词汇的说明性示例。
