海洋台站不确定性数据表示方法的研究

摘要

针对当前海洋台站数据存在不确定性的现状,在分析Trio和MayBMS两种不确定数据表示方法的基础上,结合海洋台站数据属性不确定的特点,提出一种适合于海洋台站不确定性数据的表示方法.实验结果表明,该方法能够消除现有表示方法可能产生的冗余信息并有效减少生成的关系表的数量,为今后海洋台站不确定性数据高效查询方法的研究奠定了基础.%Aiming at current status quo of the uncertainty of marine station data, in this paper we analyse two typical expressions of uncertain data, ihe Trio and the MayBMS. Based on that and according to the characteristics of uncertain data of marine stations, we introduce an expression method fitting the uncertain data of the marine stations. Experiment shows that this method can eliminate the redundant information that existing expression means may has and reduce the total number of relation tables formed effectively. It lays a foundation for the study of efficient query method for uncertain data of the marine stations.
