研究在给定的形式背景下,通过逐步添加属性建造概念格的方法.一般地,初始概念格可由部分属性生成.当添加属性时,得到了新节点与它在原概念格中的直接父节点是一一对应的结论.证明了所有新节点在原概念格中的直接父节点,只可能在某个节点和它的子节点中.基于上述性质,给出了添加属性情况下的重建概念格算法.此算法的优点是生成新节点的范围小,构建概念格的速度快.  相似文献

The concept of ‘goal-seeking’ has had a powerful influence on thinking about organizations. Whilst the concept is undeniably useful it is argued that it is also a very narrow concept of organization which can limit the way in which we think about human decision making and action. Vickers’ idea of relationship-maintenance is reviewed as a richer concept to help us think about human activity systems such as organizations. The differences between goal-seeking and relationship-maintenance are explored and explained by reference to the different way in which the concept of ‘control,’ or ‘regulation,’ is incorporated within each.  相似文献

Rough communication of crisp concept in fuzzy approximation spaces   总被引:1,自引:0,他引:1       下载免费PDF全文
To study the problem of knowledge translation in fuzzy approximation spaces, the concept of rough communication of crisp set in fuzzy approximation spaces is proposed. In a rough communication of crisp set in fuzzy approximation spares, the problem of uncertainty exists, for each agent has a different language and cannot provide precise communication to each other. By means of some concepts, such as CF rough communication cut, which is a bridge between fuzzy concept and crisp concept, cut analysis of CF rough communication is made, and the relation theorem between CF rough communication and rough communication of crisp concept is obtained. Finally, in order to give an intuitive analysis of the relation between CF rough communication and rough communication of crisp concept, an example is given.  相似文献

In a previous paper the author introduced a concept called qualifying function as a conceptual tool for modeling and design. The concept was incorporated into the modeling phase of soft systems methodology (SSM), with the purpose of addressing some of the criticism directed toward the methodology, such as its tendency to result in regulatory, rather than radical, agendas for change. It was argued that the concept had the potential to help people in a particular problem situation to view the situation from new and different perspectives and that it could enrich the conceptual models by giving the transformation process a direction. The aim of this paper is to apply the concept, embedded in SSM, to a case study involving two projects, focused on creating new work opportunities, to explore the practical applicability and usefulness of the concept, both in general and as a part of the modeling phase of SSM.  相似文献

The concept of quasi-coincidence of a fuzzy interval value in an interval valued fuzzy set is considered. In fact, this concept is a generalized concept of the quasi-coincidence of a fuzzy point in a fuzzy set. By using this new concept, the authors define the notion of interval valued (∈, ∈ Vq)fuzzy h-ideals of hemirings and study their related properties. In addition, the authors also extend the concept of a fuzzy subgroup with thresholds to the concept of an interval valued fuzzy h-ideal with thresholds in hemirings.  相似文献

In order to address the study of complex systems, the detection of patterns in their dynamics could play a key role in understanding their evolution. In particular, global patterns are required to detect emergent concepts and trends, some of them of a qualitative nature. Formal concept analysis (FCA) is a theory whose goal is to discover and extract knowledge from qualitative data (organized in concept lattices). In complex environments, such as sport competitions, the large amount of information currently available turns concept lattices into complex networks. The authors analyze how to apply FCA reasoning in order to increase confidence in sports predictions by means of detecting regularities from data through the management of intuitive and natural attributes extracted from publicly available information. The complexity of concept lattices -considered as networks with complex topological structure- is analyzed. It is applied to building a knowledge based system for confidence-based reasoning, which simulates how humans tend to avoid the complexity of concept networks by means of bounded reasoning skills.  相似文献
