Abstract 摘要
In this paper, we propose the framework for Information-based Case Grammar (IGG). This grammatical formalism stipulates that the lexical entry for each word contains both semantic and syntactic feature structures. In the feature structure of a phrasal head, we encode syntactic and semantic constraints on grammatical phrasal patterns in terms of thematic structures, and encode the precedence relations in terms of adjunct structures. Such feature structures denote partial information, which defines the set of legal phrases. They also provide sufficient information to identify thematic roles. With this formalism, parsing and thematic analysis can be achieved simultaneously. Due to the simplicity and flexibility of Information-based Case Grammar, context dependent and discontinuous relations such as agreements, coordination, long–distance dependencies, and control and binding, can be easily expressed.

本论文提出一个以讯息为本的语法模式，这个语法模式和其配合的剖析方法，可以很精确的表达及很有效率的分析中文句子。本语法模式采用词汇为中心的表达方式，将每一个词的语法及语意讯息以特征结构表示。词汇结合为词组，片词建构成句子，以中心语驱动，结合时必须符合句子中词汇所规定的语法限制。语意的合成假设具有结合性可以从词汇的语意讯息联并获得。以一语法模式保存了联并语法的所有优点而且兼顾了剖析的效率与语意的分析。
