In the last decade, members of the computational linguistics community have adopted a perspective on discourse based primarily on either Rhetorical Structure Theory or Grosz and Sidner’s Theory. However, only recently, researchers have started to investigate the relationship between the two perspectives. In this paper, we use Moser and Moore’s (1996) work as a departure point for extending Marc...

This thesis is two fold. The first part deals with an existence proof of a formal algorithm that takes a narrative discourse and returns its semantic representation in the Event Calculus (EC from now on) [19]. This algorithm uses Discourse Representation Theory, and takes on the form of a translation from Discourse Representation Structures to Scenarios and Integrity Constraints in EC. The seco...

The paper proposes a mathematical method of defining dependency and constituency provided linguistic criteria to characterize the acceptable fragments of an utterance have been put forward. The method can be used to define syntactic structures of sentences, as well as discourse structures for texts or morphematic structures for words.

This article deals with Finnish discourse oriented word-order variations, and provides their implementation in the HPSG-style typed feature structure grammar using the LKB toolkit (Copestake, 2002). It does not present a full-coverage Finnish grammar or even a small HPSG fragment of the standard syntactic phenomena in Finnish. Rather, the aim has been to implement the Finnish discourse configur...

Automatic recognition of CORROBORATE and CONTRAST relations between citations may enhance citation analysis. We describe a system that identifies these citation relations using predicate/argument and discourse structures.

The present investigation was designed to study the production and comprehension of specific means for information highlighted by advanced Iranian learners of English as a Foreign Language. The study focused on the discourse-pragmatically motivated variations of the basic word order such as inversion, pre-posing, it- and Wh-clefts. After taking the Nelson test, a homogeneous group was settled. ...

In the spoken language machine translation project Verbmobil, the semantic formalism Language for Underspecified Discourse representation structures (LUD) is used. LUD describes a number of DRSs and allows for underspecification of scopal ambiguities. Dealing with Japanese-to-English translation besides German-to-English poses challenging problems. In this paper, a t reatment of multiple discou...
