【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。更多还原

【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.更多还原
