Recent years have shown us the quick development of social network. For companies, microblog platform is more and more important as one source to disseminate brand information and monitor their development. Compared with the frequently used text information existing in traditional media, microblog platform provides information about brands in more types(More)
Our system treats coreference resolution as an integer linear programming (ILP) problem. Extending Denis and Baldridge (2007) and Finkel and Manning (2008)'s work, we exploit loose transitivity constraints on coreference pairs. Instead of enforcing transitivity closure constraints, which brings Ç´Ò ¿ µ complexity, we employ a strategy to reduce the number(More)
Mid-level semantic attributes have obtained some success in image retrieval and re-ranking. However, due to the semantic gap between the low-level feature and intermediate semantic concept, information loss is considerable in the process of converting the low-level feature to semantic concept. To tackle this problem, we tried to bridge the semantic gap by(More)
In order to solve the low accuracy problem of GPU-based FFT, a mixed precision method is employed in this paper. A "precision cache" method is proposed as the supplement of the mixed precision method to calculate of twiddle factor. A work group split method is used to reduce the latency of access global memory frequently. The mixed precision FFT achieves 3(More)
