Semantic Network Analysis of Ontologies

A key argument for modeling knowledge in ontologies is the easy re-use and re-engineering of the knowledge. However, current ontology engineering tools provide only basic functionalities for analyzing ontologies. Since ontologies can be considered as graphs, graph analysis techniques are a suitable answer for this need. Graph analysis has been performed by sociologists for over 60 years, and resulted in the vivid research area of Social Network Analysis (SNA). While social network structures currently receive high attention in the Semantic Web community, there are only very few SNA applications, and virtually none for analyzing the structure of ontologies. We illustrate the benefits of applying SNA to ontologies and the Semantic Web, and discuss which research topics arise on the edge between the two areas. In particular, we discuss how different notions of centrality describe the core content and structure of an ontology. From the rather simple notion of degree centrality over betweenness centrality to the more complex eigenvector centrality, we illustrate the insights these measures provide on two ontologies, which are different in purpose, scope, and size

Issues of Application Design for Social Studies

The given paper presents the relevant problem of software design for social welfare researches oriented towards the life satisfaction and other psychology studies which are important for social development. The aim of this paper is to show most important issues which can complicate application of algorithms and software for social studies e.g. testing and interviewing results analysis. It summarizes the elements of the Data Mining concepts which are vital for processing big amount of complex data characterized with weak mathematical formalization (as results of sociological studies). This article also includes description of requirements for software systems meant to be implemented in social studies and names existing software decisions in order to show their limitations. This allows us to conclude that this software implementations can be expanded and coordinated by means of new information system, created especially for solving this problem. And also includes short description of "MultiTest" web-portal designed to solve a number of problems associated with the social studies

Neutron diffraction studies of nanoparticle DyMnO_{3} compound

The neutron powder diffraction (NPD) measurements of the nano-size DyMnO3 manganite have been performed. The obtained results indicate that this compound crystallizes in the orthorhombic crystal structure described by the space group Pnma. The Mn and Dy moments order antiferromagnetically at different temperatures and form modulated magnetic structure described by the propagation vector k = (kx; 0; 0) with the different values of kx component for the Mn and Dy sublattices. The values of kx component for Mn sublattice increase with decreasing of the temperature and are smaller that in bulk compound. The wide Bragg peaks related to the Dy sublattice suggest that the magnetic order in this sublattice has the cluster-like character

Neutron diffraction studies of NdNi_{5}Sn compound

The neutron powder diffraction measurements of the NdNi5Sn compound have been performed. The obtained results indicate that this compound crystallizes in a hexagonal CeNi_{5}Sn-type crystal structure described by the space group P63/mmc. The parameters of the crystal structure at 1.55 and 14.8 K are determined. In contradiction to the magnetic data the long-range magnetic ordering was not detected up to 1.55 K

Well-being of Pensioners. A Subjective Assessment of the Life's Quality (By the Example of China and Russia)

The well-being of pensioners depends on not only objective factors, but also subjective. Subjective assessment of the life's quality occupies an irreplaceable position in the welfare of pensioners. This study is limited by the following restrictions: results of the survey (80 profiles in Russia, 154 questionnaires in China): 18 questions for both objective and subjective assessments; deviation of the quality of life of pensioners in Russia and China; recommendations for improving pension policy (from the standpoint of the interests of the person and the state).We proved hypothesis that, despite the significant differences assessment of the life's quality and welfare of older persons in China and Russia, subjective assessment is important. A key way of the well-being of older persons is a union of state support, personal and corporate resources
