What Do You Mean You're in Trafalgar Square? Comparing Distance Thresholds for Geospatial Prepositions

Authors: Niloofar Aflaki, Kristin Stock, Christopher B. Jones, Hans Guesgen, Jeremy Morley, and Yukio Fukuzawa

Published in: LIPIcs, Volume 240, 15th International Conference on Spatial Information Theory (COSIT 2022)

Abstract
Natural language location descriptions frequently describe object locations relative to other objects (the house near the river). Geospatial prepositions (e.g.near) are a key element of these descriptions, and the distances associated with proximity, adjacency and topological prepositions are thought to depend on the context of a specific scene. When referring to the context, we include consideration of properties of the relatum such as its feature type, size and associated image schema. In this paper, we extract spatial descriptions from the Google search engine for nine prepositions across three locations, compare their acceptance thresholds (the distances at which different prepositions are acceptable), and study variations in different contexts using cumulative graphs and scatter plots. Our results show that adjacency prepositions next to and adjacent to are used for a large range of distances, in contrast to beside; and that topological prepositions in, at and on can all be used to indicate proximity as well as containment and collocation. We also found that reference object image schema influences the selection of geospatial prepositions such as near and in.

Interpreting Observed Action (Dagstuhl Seminar 12491)

Authors: Susanne Biundo-Stephan, Hans Werner Guesgen, Joachim Hertzberg, and Stephen R. Marsland

Published in: Dagstuhl Reports, Volume 2, Issue 12 (2013)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 12491 "Interpreting Observed Action". The aim of the seminar was to get a coherent picture, which transcends the borders of applications and disciplines, of existing approaches and problems in interpreting observed action in semantic terms -- primarily action by humans, but action by artificial agents may play some role, too. The seminar brought together, on the one hand, researchers from the different camps of AI, robotics, and knowledge-based systems who are working on the various aspects and purposes of interpreting observed action by humans, or occasionally, other agents; on the other hand, it added some researchers from cognitive science (psychology, neurosciences) working on human perception of behaviour and action. The main outcome of the seminar were a set of guidelines for setting up a workbench, which can be used to explore and test methods and techniques related to interpreting observed action.
