Face recognition has been a hot issue in the flied of computer vision, and face recognition is increasingly applied in the actual life. However, some low dimensional features such as Gabor, LBP, SIFT couldn't achieve a good performance of face feature presentation. So an algorithm which based on the...

Chunk Grammar, as the basic research in natural language understanding technology, is very important in language research area. In this paper FSA(Finite State Automaton) technology was introduced to parse chunk in order to simplify the parsing procedure of the syntax and improve the accuracy of parsing...

With the office automation and development of paperless needs, the electronic homework is more and more widely used in colleges and universities, but the characteristics of being easier to copy makes copying phenomenon more and more serious, the cost of copying homework is lower and lower. Therefore...
