摘要
现代搜索引擎中的搜索算法已经成为影响搜索引擎效率的一个关键,通过对现有搜索引擎中搜索算法的研究分析,提出了一种面向搜索引擎的基于集合模型的搜索算法,该方法利用集合运算方便并、交运算的特点,把检索问题转化为集合运算问题,这使得建立索引的过程和检索的过程简单化。实验表明,该方法能够有效的提高搜索引擎的搜索效率。
Presently, the search algorithm of modern search engine is a key to the efficiency of search engines. This paper presents a search algorithm based on the collection model oriented search engine through research and analysis of existing search algorithms. This method transforms the indexing problem to set computing problem and uses the useful characteristics of union and intersection for set operation, which makes the simplification of indexing process and retrieval process. Experiments show that the method can improve the search efficiency of search engine.
