"基于Nutch的搜索引擎系统设计与实现研究"

f information, network search engines are attracting more and more attention. This paper conducts an in-depth analysis of search engine technology, specifically focusing on the Nutch software package's working mechanism. Taking into account the requirements of Chinese information processing, the Nutch software package is improved, and a search engine system with good scalability is designed and implemented. Firstly, Chinese word segmentation technology is introduced in this system, improving the query accuracy of the original search engine system. Secondly, this paper designs a ranking strategy based on the PageRank algorithm and webpage relevance. Lastly, a user interface module is designed to enhance the overall performance of the search engine system. Overall, the study in this paper presents a comprehensive analysis of search engine technology, with a focus on the Nutch software package. The improvements made to the Nutch software package have resulted in the development of a search engine system that is more accurate in query processing, has a better ranking strategy, and an enhanced user interface module. These enhancements ultimately contribute to the system's overall performance and usability.
