| Abstract: | The key of FTP Search Engine is Chinese word segmentation and retrieval technique. We use a Forward Maximum Matching Chinese word segmentation algorithm optimized for FTP Search Engine, and take the retrieval keywords as feedback to update the dictionary affiliated with the segmentation algorithm. With the conbination of this scheme with the revert index technique, a high performance FTP Search Engine prototype is implemented. The results of load test have shown that the engine is of high performance. |
