人工命题的缺陷分析与改革探索

通过对传统人工命题活动的分析和研究,指出了人工命题中普遍存在的各种固有缺陷及其给考试质量带来的不良影响,在此基础上提出机器命题的概念和用机器命题代替人工命题的改革设想,并对机器命题的过程和应用意义作了初步的论述.

纵邻非补10阶拉丁方在珠算上的应用

设有几个记号构成的集合 A={a1,a2,……an} 若把每个记号各取n回,共取得n2个,排列成n行n列的正方形,满足在各行各列上A的每个记号各出现一次,则称此正方形为A上的拉丁方或n阶拉丁方。 容易证明,对于任意自然数n,n阶拉丁方总是存在的。事实上,第一行取a1,a2,……an,第二行取an,a1,a2……an-1。

Implementing Semantic Deduction of Propositional Knowledge in an Extension Multi-layer Perceptron

The paper presents an extension multi-laye r p erceptron model that is capable of representing and reasoning propositional know ledge base. An extended version of propositional calculus is developed, and its some properties is discussed. Formulas of the extended calculus can be expressed in the extension multi-layer perceptron. Naturally, semantic deduction of prop ositional knowledge base can be implement by the extension multi-layer perceptr on, and by learning, an unknown formula set can be found.

Analysis——Phenomenology——Morphology：Some Remarks on Ludwig Wittgenstein＇s Philosophical Method

The article discusses the problem of the unity of Ludwig Wittgenstein＇s philosophy. It is demonstrated that Wittgenstein applied two methods of study. Changes in his philosophy are correlated with modifications in his method of thinking and investigation. In his Tractatus Logico-Philosophicus, the only correct method is logical proposition analysis. In the early 1930s, he transformed his philosophy into a phenomenological description of experience, defining its aim as the development of phenomenological language. After 1933, Wittgenstein recognised the grammatical dimension of language and created tools of grammatical analysis. He introduced the notions of language-games and life forms. His philosophy turned into morphology and a description of human language practice.

机器命题模式的研究

提出了在对命题题材进行恰当地描述的基础上计算机自动命题的思想;并给出了一种具体的题材描述模型,以及在该模型上基于集合和逻辑运算的机器命题规则,试用结果表明:机器命题是可行的且具有很好的开放性、多样性和实时性。
