ABSTRACT: This paper describes a system developed to help people explore local communities by providing navigation services in social spaces created by the community members via communication and knowledge sharing. The proposed system utilizes data of a community's social network to reconstruct the social space, which is otherwise not physically perceptible but imaginary, experiential, yet learnable. The social space is modeled with an agent network, where each agent stands for a member of the community and has knowledge about expertise and personal characteristics of some other members. An agent can gather information, using its social "connections", to find community members most suitable to communicate to in a specific situation defined by the system's user. The system then deploys its multimodal interface, which "maps" the social space onto a representation of the relevant physical space, to locate the potential interlocutors and advise the user on an efficient communication strategy for the given community. Comment: 16 pages, 3 figures, 5 tables.

ABSTRACT: This paper deals with the statistical analysis of social networks, and it consists of two parts. First, a survey of the existing,
power-law -inspired approaches to the modeling of degree distributions of social networks is conducted. It is argued, with
the support of a simple experiment, that these approaches can hardly accommodate and comprehensively explain the range of
phenomena observed in empirical social networks. Second, an alternative modeling framework is presented. The observed, macro-level
behavior of social networks is described in terms of the individual, “hidden” dynamics, and the necessary equations are given.
It is demonstrated, via experiments, that a Laplace-Stieltjes hypertransform of the distribution function of human decision-making
or reaction time often provides for an adequate model in statistical analysis of social systems. The study results are briefly
discussed, and conclusions are drawn.

ABSTRACT: Building on ideas from linguistics, psychology, and social sciences about the possible mechanisms of human decision-making, we propose a novel theoretical framework for the citation analysis. Given the existing trend to investigate citation statistics in the context of various forms of power and Zipfian laws, we show that the popular models of citation have poor predictive ability and can hardly provide for an adequate explanation of the observed behavior of the empirical data. An alternative model is then derived, using the apparatus of statistical mechanics. The model is applied to approximate the citation frequencies of scientific articles from two large collections, and it demonstrates a predictive potential much superior to the one of any of the citation models known to the authors from the literature. Some analytical properties of the developed model are discussed, and conclusions are drawn. Directions for future work are also given at the paper's end.

ABSTRACT: Modeling human dynamics responsible for the formation and evolution of the so-called social networks - structures comprised of individuals or organizations and indicating connectivities existing in a community - is a topic recently attracting a significant research interest. It has been claimed that these dynamics are scale-free in many practically important cases, such as impersonal and personal communication, auctioning in a market, accessing sites on the WWW, etc., and that human response times thus conform to the power law. While a certain amount of progress has recently been achieved in predicting the general response rate of a human population, existing formal theories of human behavior can hardly be found satisfactory to accommodate and comprehensively explain the scaling observed in social networks. In the presented study, a novel system-theoretic modeling approach is proposed and successfully applied to determine important characteristics of a communication network and to analyze consumer behavior on the WWW.

ABSTRACT: This paper investigates the concept of digital city. First, a functional analysis of a digital city is made in the light of
the modern study of urbanism; similarities between the virtual and urban constructions are pointed out. Next, a semiotic perspective
on the subject matter is elaborated, and a terminological basis is introduced to treat a digital city as a self-organizing
meaning-producing system intended to support social or spatial navigation. An explicit definition of a digital city is formulated.
Finally, the proposed approach is discussed, conclusions are given, and future work is outlined.
