Inferring user attributes is important for user profiling, retrieval, and personalization. Most existing work infers user attribute independently and ignores the relations between attributes. In this work, a new method is proposed to infer user attributes via hypergraph learning. In the hypergragh, each vertex represents a user in the social media, and the hyperedges are used to capture the similarity relations of the user generated content and the relations between attributes. The user attributes inference is formalized into a regularization label similar propagation problem in the constructed hypergraph, which can effectively infer the users' various attributes. Extensive experiments conducted on a collected dataset from Google+ with full attribute annotations demonstrate the effectiveness of the proposed approach in user attribute inference.
