Purpose – The purpose of this paper is to analyse institutional and functional development of a library with the help of communication theories. The library as a social institution should have a quite strong position in today’s information society, but new ways of information search have made its position unstable. Thus, a library needs theoretical and cultural-political comprehension and reassessment. The paper tries to answer the questions as to how a library can satisfy the needs of modern society and which strategy of library communication will be in demand tomorrow. Design/methodology/approach – The theoretical background is represented by communication theories of Marshal McLuhan, Denis McQuail and Yuri Lotman, as well as Michel Foucault’s concepts of disciplinary power and governmentality. Findings – The analysis revealed that library–user communication is based primarily on power relations, where “access” is the main keyword. The article brought out differences in library communicative processes in the “Gutenberg Galaxy” and today’s global network society, “Zuckerberg Era”. The analysis showed that library–user relationship is shifting from disciplinary power and monologue to the governmentality and new communicative forms, dialogue and participation. Research limitations/implications – The study demonstrates the possibility of implication of communication theories for library functional analysis. The new studies investigating which methods and forms of communication do libraries use today, how are the elements of power relations transforming would be very useful for the understanding of the topic. Practical implications – The study proposes to libraries some ideas that may be useful for developing the library communication strategy. Originality/value – This study, based on the communicative approach, corresponds well to library phenomenon and nature, as well as allows for reflection on the role of libraries in the society of today and future.

Background/Objectives: It is still a challenging issue to represent the reification effectively since the reification representation of RDF standard has been revealed some drawbacks.Methods/Statistical analysis: Currently, there are two main graph data models: RDF and LPG. LPG is a popular graph data model that is usually applied to NoSQL graph databases.This paper derives three types of the reification structures in terms of the structural and semantic relationships of the reification statements. The detailed representation of each type of the reification is presented with the extended LPG model.Findings: This paper proposes a novel approach to represent the reification structure of RDF from the perspective of LPG. The paper explores the formal, conceptual properties of the conventional LPG models and proposes their extension to capture more complex knowledge structures efficiently. These augmentations of LPG can achieve more efficient and flexible resource modeling. This paper derives three types of the reification structures in terms of the structural and semantic relationships of the reification statements: assertion, quantification, and entailment.The proposed approach not only preserves the structure and semantics of the reification but also enables LPG modeling of the complex structural statements to be easy and intuitive.This can contribute to transfer RDF graphs into LPGs.Improvements/Applications: The implementation of the extended LPG and the query processing of the reification remain future work.

A social network defines the structure of a social community like an organization or institution, covering its members and their inter-relationships. Social relationships among the members of a community can be of different types like friendship, kinship, professional, academic, and so forth. Traditionally, a social network is represented by a directed graph. Analysis of graph structure representing a social network is done by the sociologists to study a community. Hardly any effort has been made to design a data model to store and retrieve social-network-related data. In this paper, an object-relational graph data model has been proposed for modeling a social network. The objective is to illustrate the power of this generic model to represent the common structural and node-based properties of different social network applications. A novel, multi-paradigm architecture has been proposed to efficiently manage the system. New structural operators have been defined in the paper and the application of these operators has been illustrated through query examples. The completeness and the minimality of the operators have also been shown.
