Cognitive Approach in Classification Visualization: end-users study

Abstract

Visualization of scientific information extends the possibility to explore how the science is organized and change over time. Particularly classified data include a great potential of discovering the structure and dynamics of specifi ed domain. The authors applied tested and previously presented conception of ACM CCS (Computing Classification System) classification mapping into a sphere surface. This visualization layout could be mainly used as a multiperspective analytical tool of classification structure. Classification sphere also might be considered as an ergonomic interface for exploring scientific resources as well as information retrieval. Classified documents form patterns according to their semantic similarity. Obtained graphical representations deliver quantitative material for analysis of classifi cation development and dynamics. The authors try to fi nd reliable tools to evaluate this spherical visualization design. They constructed an appropriate interface and surveyed the distinct groups of users, who were asked about key aspects of visualization layout. Results of our study allow evaluating classifi cation visualization thereby improving proposed methodology as well as discovering new semantic features and laws in visual layout.
