XML 中基于聚类的相似度改进算法磁

摘要

On XML query ,the keyword query is usually used which is often not accurate due to the ambiguous of the key ‐word .In view of these reasons ,the key word clustering analysis is put forward in this paper ,and based on the diversification of the similarity of the weighted clustering to improve the accuracy of clustering ,so as to improve the accuracy of the query .%在进行 XML 查询时，通常使用关键字查询，关键字查询往往由于关键字的模糊不清造成查询结果不准确，鉴于此类原因，论文提出对关键字进行聚类分析，并通过对聚类的相似度进行多元化加权来提高聚类的准确性，从而提高查询的精确度。
