【摘要】 知识规则库的准确度是影响BBS舆情分析系统能否准确高效地对BBS舆情进行监控的一个重要因素.Apriori算法作为关联规则挖掘的经典算法,是发现关联规则的一种准确有效的方法.通过利用Apriori算法来动态更新知识规则库内容,实验结果表明,系统使用该算法后对BBS舆情监视的准确度有明显的提高.更多还原

【Abstract】 The accuracy of knowledge rule base is an important factor to affect BBS public opinion analysis system whether it can monitor BBS public opinion accurately and efficiently or not.As a classical association rule mining algorithm,Apriori algorithm is an accurate and effective way to discover association rules.In this paper,Apriori algorithm is used to dynamically update the contents of knowledge rule base.Experimental results show that the system obviously improves the accuracy of monitoring BBS public opinion by means of this algorithm.更多还原
