It is important to integrate contextual information in order to improve the inaccurate results of current approaches for automatic image annotation. Graph based representations allow incorporation of such information. However, their behaviour has not been studied in this context. We conduct extensive experiments to show the properties of such representations using semantic relationships as a type of contextual information. We also experimented with different similarity measures for semantic features and results are presented.
