Visualization in information retrieval: a three-level analysis

Visualization in information retrieval (IR) is a rapidly emerging area in which human-computer interaction (HCl) is adapted to the design of interfaces for IR systems. There are numerous proposals for the development of new visual IR systems. In parallel with the advent of advanced software and hardware, the attempts to design visualization-based IR systems are stimulated with the promise that information visualization applies visual processing to abstract information. Under this rapid development in the research area, there are few attempts to conceptualize this new field of study. This paper intends to classify the works of visualization for IR system design in a systematic way, by providing a mosaic view of the emerging area of visualization in IR system design. The paper proposes a three-level approach to analyzing visualization in IR system design: (i) component level analysis, (ii) technique level analysis and (iii) interaction level analysis. This three-level approach helps us to understand the state of visualization for the design of IR systems in multiple ways. The three-level approach also enables us in further serious investigation in this emerging field that has been created by the intersection of visualization and IR, by allowing us to look at different layers of visualization in IR that have both technical and theoretical concerns.
