The distance-similarity metaphor in region-display spatializations
Sara Irina Fabrikant, D.R. Monteilo, David M Mark · IEEE Computer Graphics and Applications · 2006
Region-display spatializations represent documents metaphorically as points within regions. Semantic interrelatedness is expressed by some combination of interpoint distance and region membership. In two experiments, the authors investigate judgments of document similarity as a function of these variables. Distance matters, but region membership largely determines judged similarity; hue further modifies it. Spatial metaphors are a popular approach to visualizing information in such forms as information worlds, information spaces, and cyberspaces.
