蕴含语义的不确定时态的表示及处理是不确定时态信息和自然语言处理领域中的重要问题，不确定时态跨度是不确定时态中的重要组成部分，而不确定的语义是造成时态跨度不确定性的根源。提出对不确定语义进行转换的思想，将其转换为邻域或区间的形式，成为可计算问题；进而从粒度层面对不确定时态跨度进行了有效刻画，给出了元组化的模型，使其可以参与运算；提出了时态粗糙集将时态跨度元素在离散状态下进行划分，采用下近似和上近似的思想划分了不确定时态跨度中的确定元素和不确定元素；并提出了不确定时态跨度的近似精确度计算方法。

Presentation and processing of uncertain temporal which contains semantics are important is-sues in uncertain temporal information processing and natural language processing.Uncertain temporal span is an important part of uncertain temporal, however, the uncertain semantics is the root of uncertain-ty.This paper proposes the idea of converting the uncertain semantics to the forms existing in neighbor-hoods or intervals that could be calculated and described on the granularity level.At the same time, a tu-ple model was given to render uncertain temporal span to join the calculation.Then a temporal rough set is suggested to divide the certain or uncertain elements of temporal span according to lower approximation and upper approximation.Finally, the approximate accuracy calculation of uncertain temporal span is presented.
