In this work, we employ the ontology of artistic concepts that includes visual (or atomic) concepts at the intermediate level and high-level concepts at the application level. Visual-level color and brushwork concepts are widely used by art historians to analyze paintings and serve as cues for annotating high-level concepts such as the artist names, painting styles and art periods for paintings. In this research we combine the color and brushwork concepts with low-level features and utilize the transductive inference framework to annotate high-level concepts to the image blocks. In order to resolve conflicting assignments of high-level concepts, we further employ the ontology-based concept disambiguation method and generate image-level annotations. This method performs global optimization of the block-level annotations using the linear constraints extracted from domain knowledge. Our experiments on annotating high-level concepts demonstrate that: a) the use of visual-level concepts significantly improves the accuracy as compared to using low-level features only; and b) the proposed transductive inference framework out-performs the conventional baseline methods and c) the proposed ontology-based disambiguation method generates superior results for several annotation scenarios.
