Summary

Image categorization research has created knowledge on the types of attributes humans use in interpreting image similarity. Little effort has gone into studying the effect of any wider contextual factors on the image groupings people create. This paper reports the results of an investigation on the effect of associated text on magazine image categorization. Image journalism professionals performed a two-phase free sorting of 100 test images and the resulting data was analyzed both qualitatively and quantitatively; using grounded theory methods and hierarchical clustering. The categorization behavior of the two groups was similar but there was a statistically significant difference in the types of names given to the categories constructed. Results indicate that having page context available results more likely in descriptions based on overall theme or story of the image. When the context is withheld, people are more prone to describe the people, objects and scenes portrayed in the images, and combine various categorization criteria. This has implications for the design of interfaces for image archival and retrieval.
