Automatic taggers describe music in terms of a multinomial distribution over relevant semantic concepts. This paper presents a framework for improving automatic tagging of music content by modeling contextual relationships between these semantic concepts. The framework extends existing auto-tagging methods by adding a Dirichlet mixture to model the contextual co-occurrences between semantic multinomials. Experimental results show that adding context improves automatic annotation and retrieval… CONTINUE READING
