In this paper, we propose an approach to constructing the user interface to be based on the ontological description. Its advantages are pondered. The main value using the ontology is the reduced complexity and development time as well as the increased quality of resulting implementation. The requirements to a system...
The paper discusses the problems of the development and maintenance of information systems on the basis of ontology and Wiki-technology. In particular, an approach including the method of constructing information systems using Wikitechnology and ontology of subject domain and the method of ontology extraction from the already existing Wiki-systems is...
The process of development of an ontology-based knowledge portal and creation of its content is time-consuming and labor-intensive. It is very desirable to have special analysis facilities for maintenance and development of such a portal. The subject of our paper is a tool for visual analysis of content and ontology...
The process of development of an ontology-based knowledge portal and creation of its content is time-consuming and laborious. The lifetime of such portals is sufficiently long and they collect a great volume of valuable information. This information can be analyzed from various points of view. This paper describes an extension...
We examine a number of methods for probing and understanding a large-scale structure of networks that evolve over time. In particular, we focus on citation networks, networks of references between documents such as research papers. We describe three different methods of visualization: the first is based on a hierarchical edge...
The paper discusses an experience of using the methodology for the development of knowledge portals which provide systematization and integration of scientific and engineering knowledge and information resources as well as the content-based access to them. To provide a sufficiently complete and consistent representation of knowledge and information resources, their...
