最近已经开发了通过交互性质疑专家来构建知识空间的抽象程序。知识空间是适合评估学生知识的结构。知识空间被定义为特定的考试问题亚集集集合。知识空间的基础是可以重建知识空间的知识空间的最小子集合。在构建知识空间的过程中，要求专家接受或拒绝有关考试问题集的某些断言。通过省略可以从以前的判断中推断出的那些判断来减少可能的判断数量。本文的结果可用于从专家的判断中构建知识空间的基础。以这种方式，可以改善先前建议的询问专家的程序。首先，确定是否可以从先前判断中推断出判决所需的迭代次数大大减少，其次，新程序不需要对提出主张提出判决的顺序的假设，第三，最糟糕的是可以避免专家必须做出所有可能的判断的情况。
Abstract Procedures for constructing a knowledge space by interactively questioning an expert have been recently developed. Knowledge spaces are structures appropriate for the assessment of student's knowledge. A knowledge space is defined as a specific collection of subsets of examination questions from a given field. The basis of a knowledge space is the smallest sub-collection of a knowledge space from which the knowledge space can be reconstructed. During the procedures for constructing a knowledge space, the expert is asked to accept or reject certain assertions on the set of examination questions. The number of possible judgments is reduced by omitting those judgments which can be inferred from previous judgments. The results of this paper can be applied to construct the basis of a knowledge space from the judgments of an expert. In this manner, previously suggested procedures for questioning experts can be improved. First, the number of iterations required to decide whether or not a judgment can be inferred from previous judgments is reduced considerably, and second, the new procedure does not require assumptions on the sequence in which the assertions are presented for judgment, Third, the worst case, in which the expert has to make all possible judgments, can be avoided.
