Spatial Information Annotation Based on the Double Cross Model

Abstract

Spatial ML and ISO-Space have been proposed as methods to describe spatial information that appears in a language. Although these methods are effective for describing proper position information and absolute references (such as cardinal directions), they are not suitable for describing the relative references (such as front, back, left, and right) inherent in dialogue as entities in space. Ambiguity in relative references cannot be resolved using only directed edges (ordered pairs), and it is necessary to maintain two or more directed edges as frames, including the orientation of the entities. The double cross model is used in spatial logic to resolve the ambiguity of location information. In this study, we attempted to represent relative references in dialogue using the double cross model and present our findings.
