Explicit visual representations of domain knowledge have the potential to support students engaged in scientific inquiry learning activities on an epistemic level. This can be facilitated using computational methods for the extraction of concepts from student generated knowledge artefacts such as hypotheses, concept maps, or wiki articles. We propose an application of this approach in the conte...

One of the main problems in FCA (especially in fuzzy setting) is to reduce a concept lattice to appropriate size to make it graspable and understandable. We generalize known results on the correspondence of block relations of formal contexts and complete tolerances on concept lattices to fuzzy setting. Using an illustrative example we show that the results can be used for reduction of fuzzy con...

The most general algebraic structure of truth-values considered in the theory of fuzzy concept analysis to evaluate the attributes and objects has been a lattice. However, in some examples arises the necessity of a more general structure. In this paper we investigate the use of multilattices as underlying set of truth-values for these attributes and objects.

Following suggestions by anthropologists, (Tylor, Malinowski, Benedict, and White), social psychologists (G.H. Mead), sociologists (Goffman and Berger and Luckmann), and philosophers (Ricoeur and Cassirer), I propose a characterization of the anthropological concept of culture using the institution as the fundamental unit of cultural analysis and show how this characterization can address a num...

Research on terminology services has resulted in development of applications and definition of standards, but has not yet led to widespread use of (standardized) terminology services in practice. Current terminology services offer functionality both for concept representation and lexical knowledge representation, hampering the possibility of combining the strengths of dedicated (concept and lex...

The concept mapping and the Vee diagram are important tools for improving the level of conceptual learning of mathematics in all educational levels that can play an important role in the learner's achievement. The purpose of this study is to use a concept mapping and Vee diagram, to calculate the volume of an object by the integral, includes the reaction of what a teacher really knows, the way ...

The paper provides an exploratory empirical survey of Application Service Providers (ASPs) and their clients. The research question is: what do Small and Medium-sized Enterprises (SMEs) base their decision on when adopting the ASP concept? The concept, ASP, consists of software vendors, and an ASP enterprise, which act as a third part firm in a business model. For its clients it forms a strateg...

Personalized study planning framework consists four graphs for personalized study planning: a graph representing a conceptual structure of study program; a graph representing study course; a graph visualizing each topic of study course using concept map; a graph representing learning objects. This paper describes third graph – a graph for study course topic structure displaying and knowledge as...

Modern web sites commonly interact with thirdparty domains to integrate advertisements and generate revenue from them. To improve the relevance of advertisements, online advertisers track user activities online with third-party cookies. However, excessive online tracking might cause unreasonable access to users’ browsing information. Users are thus in need of a simple way to control the sharing...
