基于Xcluster的XML数据库模糊查询方法
Fuzzy Query Base on Xcluster of XML Database
为了减少在Web上进行精确的XML检索代价，提出查询表达式松弛策略并定义信息损率计算公式。在此基础上给出基于Xcluster的XML模糊查询小枝TFIDF评分方法并实现其算法。实验结果表明该方法的有效性并具有常数查全率和较高的查准率。
In order to reduce cost of precise XML retrieval on Web,the query expression relaxation strategy is proposed and the computing formular for information lost rate is defined. According to this , the twig scoring method of XML fuzzy retrival based on Xcluster is proposed and the algorithm has been implemented.The expriment results show the method is effective and has the characteristic of constant recall and high precision.
