Qualitative Spatial Reasoning about Sketch Maps
tation used in many geospatial-reasoning tasks. This article describes techniques we have developed that enable software to perform humanlike reasoning about sketch maps. We illustrate the utility of these techniques in the context of nuSketch Battlespace, a research system that has been successfully used in a variety of experiments. After an overview of the nuSketch approach and nuSketch Battl...
متن کاملMulti-query optimization for sketch-based estimation
Randomized techniques, based on computing small ‘‘sketch’’ synopses for each stream, have recently been shown to be a very effective tool for approximating the result of a single SQL query over streaming data tuples. In this paper, we investigate the problems arising when data-stream sketches are used to process multiple such queries intelligently sharing sketches among concurrent query evaluat...
متن کاملEfficient Learning of Qualitative Descriptions for Sketch Recognition
We are trying to solve the problem of learning to recognize objects in an open-domain sketching environment. Our system builds generalizations of objects based upon previous sketches of those objects and uses those generalizations to classify new sketches. We represent sketches qualitatively because we believe qualitative information provides a level of description that abstracts away details t...
متن کاملManaging Qualitative Spatial Information to Support Query-by-Sketch
In this paper, we propose an extension of existing geographic information systems to support querying-by-sketch. It makes use of a particular class of queries, called qualitative spatial configuration queries, to match sketch-maps against spatial datasets. After analyzing several approaches, we identify the development of a dedicated qualitative layer as the most suitable solution. To face the ...
متن کاملQualitative Representations of Extended Spatial Objects in Sketch Maps
With the advent ofVolunteeredGeographic Information (VGI) the amount and accessibility of the spatial information such as sketched information produced by layperson increased drastically. In many geo-spatial applications, sketch maps are considered an intuitive user interaction modality. In sketch maps, the spatial objects and their relationships enable users to communicate and reason about the...
