Abstract

We introduce a modular, dependency-based formalization of Information Structure (IS) based on Steedman's prosodic account [1,2]. We state it in terms of Extensible Dependency Grammar (XDG) [3], introducing two new dimensions modeling 1) prosodic structure, and 2) theme/rheme and focus/background partitionings. The approach goes without a non-standard syntactic notion of constituency and can be straightforwardly extended to model interactions between IS and other dimensions such as word order.
