Semantic Annotation for Places in LBSN through Graph Embedding [PDF]
Proceedings of the 2017 ACM on Conference on Information and Knowledge Management, 2017 With the prevalence of location-based social networks (LBSNs), automated semantic annotation for places plays a critical role in many LBSN-related applications. Although a line of research continues to enhance labeling accuracy, there is still a lot of room for improvement. The crucial problem is to find a high-quality representation for each place. In
