A Lexical Analysis based network access control system design and Implementation
AbstractAiming at the problem that the current public opinion invention system relying on manual input sensitive pages and the lacking tolerance, this paper designs a more advanced system of public intervention with intelligence, flexibility and efficiency. The system is based on the Chinese Academy’s Chinese word segmentation system ICTCLAS and redevelops the lexical analysis module. It uses the cosine distance vector calculation model instead of Boolean matching to improve the accuracy of similarity calculation; By threshold control, the system has the controllability and flexibility; Finally, the paper shows a PC-based Java test program, verifying the validation of the algorithm from the judgment accuracy and the run-time aspects, etc.
