基于索引属性改进的OPIC算法

Improvement of OPIC Algorithm Based on Indexed Properties

搜索结果的可靠性是影响广大网民使用搜索引擎的一项重要指标.在开源OPIC算法的基础上,提出了TS算法,该算法通过基于索引属性的改进,加入网页的创建时间和网页深度两个属性,使得网页的评分不仅仅局限于网页的链接,实现了网页评分因素的多元化.而网页最后的排序分值在原有OPIC算法的基础上与网页创建时间成正比,与网页深度成反比,有效改善了OPIC算法偏重历史网页的缺点,使搜索结果更加合理.最后,对TS算法进行效果演化,经过与传统搜索结果的分析对比,显示本算法返回的结果具有更高的可靠性.

The reliability of search results is an important index affecting the majority of Internet users use search engines. TS algorithm is proposed based on the open source OPIC algorithm. The algorithm is based on improved indexing attribute and to create two properties includes Webpage creation time and Webpage depth added to TS algorithm to realize the diversification Webpage score. This can improve the disadvantages of the OPIC algorithm emphasis on the history of the page, to make the search results more reasonable. Finally, it is proved by experiments that the result of TS algorithm is more reliable.
