摘要: Web垂直搜索引擎是一个复杂的信息系统,目前大多数研究都集中在解决搜索引擎中出现的某一个方面的问题,仍缺乏对Web垂直搜索引擎完整实现过程的相关研究。针对这个问题,提出一种三层架构的Web垂直搜索引擎的实现过程,整个过程包含数据准备、查询处理和界面交互。使用Java语言和相关的开源工具,对实现过程描述的具体任务进行实际

操作,实现了一个查询手机信息的Web垂直搜索引擎。该三层架构和实现过程有效地为构建面向主题的完整Web垂直搜索引擎提供了理论依据和实践指导。

Abstract: The Web search engine is a complex information system. However, most researches are concentrated on one detailed problem appearing in a aspect of the search engine, but they lack of the correlational research on the complete implementation process of Web vertical search engines. Aiming at this problem, the implementation process of a Web vertical search engine with a

three?layer architecture is proposed, in which data preparation, query processing and interface interaction are contained. An actual operation of a certain task describing the implementation process was performed with Java platform and relative open?source tools. And by this operation, the Web vertical search engine that could query mobile information was realized. The three?layer architecture and implementation process provide a theoretical basis and practical guidance for building a complete subject?oriented Web vertical search engine.

Keywords: Web search; search engine implementation; architecture of vertical search engine; crawler
