GRAPH: The Costs of Redundancy in Referring Expressions
نویسندگان
چکیده
We describe a graph-based generation system that participated in the TUNA attribute selection and realisation task of the REG 2008 Challenge. Using a stochastic cost function (with certain properties for free), and trying attributes from cheapest to more expensive, the system achieves overall .76 DICE and .54 MASI scores for attribute selection on the development set. For realisation, it turns out that in some cases higher attribute selection accuracy leads to larger differences between system-generated and human descriptions.

Controlling Redundancy in Referring Expressions
Krahmer et al.’s (2003) graph-based framework provides an elegant and flexible approach to the generation of referring expressions. In this paper, we present the first reported study that systematically investigates how to tune the parameters of the graph-based framework on the basis of a corpus of human-generated descriptions. We focus in particular on replicating the redundant nature of human...
متن کاملA New Model for Generating Multimodal Referring Expressions
We present a new algorithm for the generation of multimodal referring expressions (combining language and deictic gestures).1 The approach differs from earlier work in that we allow for various gradations of preciseness in pointing, ranging from unambiguous to vague pointing gestures. The model predicts that linguistic properties realized in the generated expression are co-dependent on the kind...
متن کاملNeed I Say More? On Factors Causing Referential Overspecification
We present the results of an elicitation experiment conducted to investigate which factors cause speakers to overspecify their referential expressions, where we hypothesized properties of the target and properties of the communicative setting to play a role. The results of this experiment show that speakers tend to provide more information when referring to a target in a more complex domain and...
متن کاملReliability Modelling of the Redundancy Allocation Problem in the Series-parallel Systems and Determining the System Optimal Parameters
Considering the increasingly high attention to quality, promoting the reliability of products during designing process has gained significant importance. In this study, we consider one of the current models of the reliability science and propose a non-linear programming model for redundancy allocation in the series-parallel systems according to the redundancy strategy and considering the assump...
متن کاملThe Design of an Experiment in Anaphora Resolution for Referring Expressions Generation
We present a pilot experiment to measure the effects of redundancy in the resolution of definite descriptions as performed by a small number of human readers. Although originally intended to provide evidence of how much redundancy should ideally be included in generated anaphoric descriptions, preliminary findings reveal a number of little explored issues that are relevant to both referring exp...
