We report a high-performance Chinese NER system that incorporates Conditional Random Fields (CRFs) and first-order logic for the fourth SIGHAN Chinese language processing bake-off (SIGHAN-6). Using current state-of-the-art CRFs along with a set of well-engineered features for Chinese NER as the base model, we consider distinct linguistic characteristics in(More)
Digital airborne cameras play a significant role for aerial Photogrammetry development from analog to full-digital age. Because of the gap between digital sensor performance and Photogrammetry request, digital airborne also becomes the bottleneck of full-digital approach. In this paper, we present a design of twice-imaging airborne camera system with(More)
