摘　　要：基于同义属性和成组属性给出了查询转换映射机制,解决了如何从源查询串到目标查询串的较为准确的映射,实现了检索对应各源网址的转换查询子串,相应的方案应用于国内20个代表性的图书领域的Deep Web站点,较好地实现了对这些站点的Deep Web图书信息的搜索.The mapping mechanism of query translation has been advanced, which is based on synonymous attributes and group attributes. The problem of how to realize the more accurate compre- hensive mapping from the source query string to the target query string has been solved. The query substring to each source site for the realization of retrieval has been provided, the solution of this paper has been applied to 20 representative Deep Web sites which are selected from domestic books area, and the Deep Web search to these sites＇ book information is implemented.
