我们提出了一个帐户的链接模式，没有中间机制，如专题或演员/undergoer层次结构。相反，由句法和语义标准定义的对词类的约束编码语义角色和句法参数之间的概括。我们发现，链接理论需要捕捉的概括可以通过与其他词汇概括相同的机制来建模，使用词类层次结构内指定的条件。每个条件都提供了语义角色和句法参数之间映射的部分规范。我们认为，这种基于约束，动词类为基础的连接的观点提供了几个经验的优势：部分的限制和例外很容易容纳，细粒度的语义区别相关的连接是赞同的，和经济上捕获的语义和句法动词类之间的横切相似性。
We propose an account of linking patterns that does away with intermediary mechanisms such as thematic or actor/undergoer hierarchies. Instead, constraints on word classes, defined by both syntactic and semantic criteria, encode generalizations between semantic roles and syntactic arguments. We show that the generalizations a linking theory needs to capture can be modeled via the same mechanisms as other lexical generalizations, using conditions specified within the hierarchy of word classes. Each condition provides a partial specification of the mapping between semantic roles and syntactic arguments. We argue that this constraint-based, verb-class-based view of linking offers several empirical advantages: partial regularities and exceptions are easily accommodated, fine-grained semantic distinctions relevant to linking are countenanced, and cross-cutting similarities between semantic and syntactic verb classes are economically captured.
