摘要 事物的有效时间由于各种原因具有不确定性,如何表示和度量这种时态不确定性是时态数据库研究的重点。提出使用分段方式近似地存储概率分布函数,并在此存储结构上研究了时态序关系BeforeI操作,最终给出了高效的线性算法。 Because of some constraints,valid time is uncertain.It is very important to understand how to model and compute temporal indeterminacy.We try to use the method of segment to store the probability function,and study and analyze the BeforeI operation deeply basing on this data structure.Finally,a very efficient linear algorithm will be given.
