This paper presents a cross-modal approach for extracting semantic relationships of concepts from an image database. First, canonical correlation analysis (CCA) is used to capture the cross-modal correlations between visual features and tag features in the database. Then, in order to measure inter-concept relationships and estimate semantic levels, the proposed method focuses on the distributions of images under the probabilistic interpretation of CCA. Results of experiments conducted by using an image database showed the improvement of the proposed method over existing methods.
