Social media are media contributed by common users and distributed in social networks. There may exist thousands of answers to a single question provided by different users. However, it is difficult to evaluate the authority of a user to a specific question. We introduce a new method for identifying experts in social media. Both the structure of the social network and content of the media are used in a unified graph model for evaluation of users. Extensive experiments show that our approach can determine authority experts on specific domains.
