Uncertainty is lack of believable knowledge or information about (1) all relevant antecedent conditions;(2) all possible outcomes; and (3a) either universal laws (governing deterministic outcomes as the only physically possible ones) or (3b) probability laws (governing indeterministic/stochastic sets of outcomes).

不确定性的意思就是缺乏可信赖的知识或资讯，这些知识或资讯是关於：(1)所有相关的先决条件；(2)所有可能的结果；(3a)可能是通则(支配确定的结果以作为唯一可能的结果)；(3b)机率法则(支配非确定的/随机的一组可能产出)。

At the early 1980s, is an effective mathematic tool to deal with the uncertain or fuzzy knowledge. Rough rule theory has been widely used in information retrieval, digital library, software engineering and knowledge discovery. Its main idea includes acquisition of rough decision rules by reduction of data under the condition of keeping an invariability of classification capacity. And it basically represents a concept by a pair of approximation sets according to the partition on the given data based on the indiscernibility relation. Rough sets theory is well suited to deal with inconsistency of the rough approximations. So it is a new mathematical tool dealing with vagueness and uncertainty, and has found its applications in many areas such as AI, KDD, pattern recognition and classification and fault diagnosis.
