基于元搜索的专业搜索引擎的设计

Design of Specialized Search Engine Based on Meta-Search Engine

专业搜索引擎是一种为用户提供比通用搜索引擎更多、更精准的专业信息的搜索引擎。根据搜索引擎的工作原理,提出了一种基于元搜索的专业搜索引擎的设计框架;详细介绍了信息采集、中文分词、结果处理的实现技术;将神经网络与遗传算法相结合,对元搜索结果进行过滤及排序,进一步提高了专业搜索引擎的查询效率。

Professional search engine can provide users with much more accurate professional information than general search engines.According to the operational principle of search engines,a design framework of professional search engine based on meta-search was presented,and the technology of information collection,Chinese word segmentation and results processing was introduced.For the sake of further enhancing the query efficiency of professional search engine,this system combines neural networks with genetic algorithm to filter and sort the results of meta-search.
