The Right Frontier Constraint Holds Unconditionally
نویسنده
چکیده
The paper re-opens the controversial case of the right frontier constraint. A formal proof of its applicability in models that use certain types of trees as modalities to represent the structure of discourse is given. Then its violation, reported to occur in discourses “under pressure”, is revisited and a proposal for discourse structure representation that deviates from classical trees is made.

Empirically Assessing Effects of the Right Frontier Constraint
In a questionnaire study the effects of discourse structural information on resolving inter-sentential anaphora were investigated. The Right Frontier Constraint, first proposed by Polanyi (1988), states that potential antecedents of an anaphor that are placed at the right frontier of a discourse unit can be accessed more easily than antecedents that are placed somewhere else. Participants (N=36...
متن کاملAn effective method based on the angular constraint to detect Pareto points in bi-criteria optimization problems
The most important issue in multi-objective optimization problems is to determine the Pareto points along the Pareto frontier. If the optimization problem involves multiple conflicting objectives, the results obtained from the Pareto-optimality will have the trade-off solutions that shaping the Pareto frontier. Each of these solutions lies at the boundary of the Pareto frontier, such that the i...
متن کاملThe Right Frontier Constraint as Conditional
The Right Frontier Constraint (rfc) claims that antecedents are only available for anaphoric reference if they are located at the right hand side of any level of a linearly ordered discourse parse tree. We show that this constraint does hold only under certain conditions — which, however, apply for most circumstances of everyday talk. The data of our analysis in which the rfc does not hold come...
متن کاملThe Moving Right Frontier
This paper analyzes systematic cases of revision of the discourse structure entailing a modification of the right frontier. We show that the coordinating or subordinating nature of discourse relations plays a major role in this revision, examining in particular a relation typical in narratives, Result, as well as a family of dialogues relations: contentrelations introduced by interrogatives. Th...
متن کاملTesting SDRT's Right Frontier
The Right Frontier Constraint (RFC), as a constraint on the attachment of new constituents to an existing discourse structure, has important implications for the interpretation of anaphoric elements in discourse and for Machine Learning (ML) approaches to learning discourse structures. In this paper we provide strong empirical support for SDRT’s version of RFC. The analysis of about 100 doubly ...
