摘要
针对基于短信的移动搜索软件平台中的中间软件模块,提出一种能够适应多种搜索引擎的二次排序算法ISEH。该算法考虑移动终端屏幕小、存储及处理能力弱等特点,对搜索引擎第1次查询返回的结果集从内部相似度和外部热度进行综合评估,得出最终的排序结果。基于Linux平台的算法仿真实验表明,该算法能克服传统搜索引擎海量信息返回、准确度低等缺陷,将查询满意度因子提升到63.57%,并提高了移动搜索效率。
A new secondary ordering algorithm is proposed in the middle software module of mobile search platform based on short message, which can cater for various kinds of search engines. According to the characteristics of mobile terminal such as smaller screen, weaker storing and processing ability, based on the internal similarity and external linkage degree, this algorithm totally evaluates the inquired results from search engine, and acquires the final ordering results. Experimental results based on Linux system show that this algorithm overcomes the defects of vast number of returned information and low accuracy of traditional searching engines, increases the search satisfactory factor to 63.57%, and improves the efficiency of mobile search.
