个性化PageRank算法在图书馆智能搜索引擎中的实现

Personalized PageRank Algorithm and Its Implementation in Library Intelligent Search Engines

智能搜索引擎的提出引发了新一轮搜索引擎革命,然而其实现还有一定的困难。以目前非常成熟的PageRank技术为基础进行改进,构建基于个人需要的PageRank算法,可以实现智能搜索引擎所需要的多种个性化功能。目前在大型广域搜索引擎上建立个性化的智能搜索引擎还比较困难,而高校图书馆在信息规模、用户基础和运行条件上都有建立智能搜索引擎的优势。对目前的高校图书馆检索系统进行一定的改进,可以实现智能搜索引擎的个性化功能。

The concept of intelligent search engines has initiated a new round of revolution in the corresponding field.However,its implementation has met with some difficulties.The construction of a PageRank algorithm based on individual needs,supported by today＇s mature PageRank technology,will enable the realisation of the multiple personalised functions required by intelligent search engines.At present it is comparatively difficult to build personalised intelligent search engines on the large-scale macrozonality scope,but it can partly be achieved in college libraries,which enjoy an advantage with regard to the information scale,client base and management environment.Therefore the improvement to the existing college library index system in this respect can realise the personalised functions of intelligent search engines.
