Abstract

This paper discusses two problems with LR parsing with regard to constructing parsing tables with feature-based grammars. First, we show that traditional LR parsing methods suffer from nontermination and nondeterminism problems when they are applied to feature-based grammars. We then present an LR method for feature-based grammars that avoids both nontermination and nondetermisim by making use of partial information of a feature structure. Second, we describe the problem of adapting LR parsing to feature-based grammars with schematic rules (i.e., rules that do not contain enough information to construct parsing tables). To remedy this problem, we propose a rule inference algorithm which instantiates underspecified rules into more specified ones containing enough information.

본 논문은 자질기반 문법의 LR 파싱 테이블 생성과 관련된 두 가지 문제점을 논의한다. 먼저 자질기반 문법에 LR 파싱 방법을 적용할 경우 발생하는 비종결성 및 비결정성의 문제를 살펴본 후, 이 문제를 해결할 수 있는 LR 방법을 제시한다. 또한 파싱 테이블을 생성하기에는 충분한 정보를 가지지 못하는 하위명시 규칙의 문제점을 지적하고, 이러한 규칙들을 LR 파싱 방법으로 처리할 수 있도록 하는 규칙추론 알고리듬을 제안한다.
