2) the interval of alternative's attribute value
属性值区间
3) interval-valued attributes
区间值属性
1.
Besides null-valued and layered-valued attributes, interval-valued attributes are also attributed to incomplete information.
除空值和层次型概念外 ,区间值属性的处理是典型的不完全信息问题。
2.
A improved learning algorithm of decision tree generation for interval-valued attributes is presented,and after improving, the efficiency of the algorithm is strongly improved by defining new no-stable cut points.
通过引进新的非平稳割点定义，提出了改进的区间值属性决策树学习算法，改进后学习算法的效率有很大程度的提高。
4) positive ideal point
区间多属性
1.
The method makes full use of the information about the weight,and calculates every alternatives\' positive ideal point and negative ideal point accoding to the single purpose line programming models.
针对属性权重信息不完全的区间多属性问题,将满意度的概念引入区间多属性决策,考虑决策者给出的权重信息,结合客观数据建立优化模型,得出权重,再根据综合属性值对方案进行排序。
5) multiple-attribute range query
多属性区间搜索
6) disturbing attrubute interval set
扰动属性区间集
补充资料：区间
表示实变量x的取值范围。设a、b是两个实数，且a＜b，满足a＜x＜b的实数x的集合记为(a，b)或］a，b［，称为开区间；满足a≤x≤b的实数x的集合记为［a，b］，称为闭区间。满足a≤x＜b或a＜x≤b的实数x的集合，分别记为［a，b)、［a，b［或(a，b］、］a，b］，称为半开半闭区间。
