Semantic network is an information model of knowledge domain. Objects and their relations are specified with an attributed graph. Multistripe layout is suitable for visualization of relations incident to the selected set of objects. The method provides a compact drawing that is guaranteed to avoid link crossings and label overlaps for objects and relations of corresponding subnetwork. In this paper we describe a common scheme of the multistripe layout approach and propose the way of visualization of semantic network fragments. These fragments may contain additional relations and objects in comparison with subnetworks considered earlier.
The availability of large urban social media data creates new opportunities for studying cities. In our paper we propose a new direction for this research: a joint analysis of geolocations of shared images and their content as determined by computer vision. To test our ideas, we use a dataset of 47,410 Instagram images shared in the city of St.Petersburg over one year. We show how a combination of semantic clustering, image recognition and geospatial analysis can detect important patterns related to both how people use a city and how they represent in social media.
A visibility representation of graphs in which each vertex is mapped to a horizontal segment, was originally proposed in 80s in the context of VLSI layout construction problem. In this paper we present the up-to-date survey on this representation and propose the way of its usage in visualization of semantic networks.
A general model of socio-semantic network is presented in terms of state-transitions systems. We provide some examples and indicate research directions, which seem to us the most important from the application point of view.
In this paper we consider formal model of an online community as a combination of social and semantic networks. An approach is suggested to measurement of maturity level of a professional community based on two groups of parameters, which characterize competency level and density of contacts correspondingly. We present preliminary results of the pilot testing of the proposed approach for evaluating several city IT-communities in Central Russia. The paper is based on the authors’ experience and achievements obtained in their work to develop Virtual Skolkovo online community.
This article is talking about state management and cultural policy, their nature and content in term of the new tendency - development of postindustrial society. It mentioned here, that at the moment cultural policy is the base of regional political activity and that regions can get strong competitive advantage if they are able to implement cultural policy successfully. All these trends can produce elements of new economic development.
