摘　　要：链接分析技术在信息检索中起着核心作用,是当前Web搜索引擎的核心技术。由于其具有的广泛适用性,已经被应用于社会科学领域。知识发现在公共决策中也有其相当重要性。在当前互联网信息呈指数级增长,伴随大量信息产生的背景下,文章主要研究针对公共决策的一种恰当的改进的链接结构分析算法,为公共决策应用提供了一种方法上的探索。通过对Web挖掘技术的相关链接结构方法引入权重值对其进行改进,结果表明,改进后的算法明显提高了算法的精准度,更加适宜在公共决策过程中,从庞大复杂信息系统中进行知识发现,促进公共决策更具科学性。Link analysis technology plays a central role in information retrieval.It is a core technology of the current Web search engine.Because of its broad applicability,it has been used in the social sciences.Knowledge Discovery is also very important in public decision-making.At present,It Shows exponential growth in information of internet,along with large amounts of information generated by the context,the article main research improved link structure analysis appropriate for public decisionmaking algorithms,provides a way for public decision-making.To improve the Web link structure mining method through introducing the relevant weights to it,the results show that the improved algorithm improved the accuracy of the algorithm,it is more suitable for public decision-making,discovery knowledge from the vast information,so that public decision making can be more scientific.
