Head-driven Phrase Structure Grammar: An Investigation in Linguistic Theory and Its Computational Implementation

语言学理论的这个项目正在研究一种明确的语言句法和语义理论的可能性和问题，该理论运行在单一的表示水平上，具有严格定义和限制的形式属性的规则。基础研究集中在句法、语义和语用领域的一系列相互关联的问题上。第一组涉及有关句法依存关系的信息如何确定表面顺序，以及(更一般地)用形式和计算术语表征自然语言可用的组合可能性。第二组问题涉及自然语言中出现的句法依存关系的表示。就语义学而言，该项目的目标是阐明一种理论的逻辑和本体论基础，该理论以心理实体为基础进行计算。

This project in linguistic theory is investigating the possibilities and problems of an explicit theory of linguistic syntax and semantics which operates on a single level of representation, with rules with strictly defined and restricted formal properties. The basic research focuses upon a set of interrelated issues in the areas of syntax, semantics, and pragmatics. The first set has to do with how information about syntactic dependencies determines surface order and (more generally) with characterizing the combinatorial possibilities available to natural language in formal and computational terms. The second set of issues concerns the representation of the syntactic dependencies that arise in natural language. The goals of the project with respect to semantics are to articulate the logical and ontological foundations of a theory which makes computational constructions out of mental entities.
