Design and Implementation of a Chinese Web Documents Full-Text Retrieval System

To solve the problem that some results are skipped over or some errors occur during the process of searching some words and the recall and precision are low, the application of character based indexing technology to the search of Chinese Web documents is studied. The organization structure and retrieval algorithm of character based indexing are discussed in detail. Byte aligned compression method is proposed. The structure and implementation of the entire system are described at last. This system is proved to have good response time and precision and be a practical one by tests.
