Social tags have been acknowledged as a highly useful resource in retrieving music by moods or topics. However, since social tags are open for labeling, some social tags are inaccurate. In this paper, we present a new framework to identify accurate social tags of songs. In our framework, we first clean and filter music tags. Then we apply an improved hierarchical clustering algorithm to group the tags to build a tag category. Based on the category, we classify music songs using lyrics. In order to extend the semantic information of lyrics, we apply CLOPE to cluster lyrics and use the centroid of the corresponding cluster to represent the lyrics. Based on the Na"ive Bayes method, the probability of assigning lyrics to particular class is predicted. The classification result is then used to determine whether a social tag is accurate. The experimental results show that the proposed framework is effective and encouraging.
