Absolute and Relative Properties in Geographic Referring Expressions

Abstract

This paper discusses the importance of computing relative properties and not just retrieving absolute properties when generating geographic referring expressions such as "northern France". We describe an algorithm that computes spatial properties at run-time by means of spatial operations such as intersecting and analyzing parts of wholes. The evaluation of the algorithm suggests that part-whole relations are key in geographic expressions.

Fuzzy-Based Language Grounding of Geographical References: From Writers to Readers

“…Moreover, the previous reference proposed a geographical referring expression generation algorithm that integrates the "name" reference frame with the rest of RoadSafe's frames. For this, the proposal in [23] addresses the differences between absolute and relative references and a model based on mereology is proposed, where named descriptors are combined with descriptors from other reference frames (e.g., "southwestern Moray").…”
