Science Visualization and Discursive Knowledge

  title={Science Visualization and Discursive Knowledge},
  author={Loet Leydesdorff},
Positional and relational perspectives on network data have led to two different research traditions in textual analysis and social network analysis, respectively. Latent Semantic Analysis (LSA) focuses on the latent dimensions in textual data; social network analysis (SNA) on the observable networks. The two coupled topographies of information-processing in the network space and meaning-processing in the vector space operate with different (nonlinear) dynamics. The historical dynamics of…

In search of a network theory of innovations: Relations, positions, and perspectives

A sociological perspective on innovation networks can be elaborated using Luhmann's social systems theory and Latour's “sociology of translations,” because of a common focus on communication, to drive innovation cycles.

Information, Meaning, and Intellectual Organization in Networks of Inter-Human Communication

The Shannon-Weaver model of linear information transmission is extended with two loops potentially generating redundancies: (i) meaning is provided locally to the information from the perspective of

Journal maps, interactive overlays, and the measurement of interdisciplinarity on the basis of Scopus data (1996–2012)

A global map of science based on aggregated journal–journal citations from 1996–2012 is constructed using Scopus data and can be compared with mappings based on the Journal Citation Reports at the Web of Science.

Mapping patent classifications: portfolio and statistical analysis, and the comparison of strengths and weaknesses

The Cooperative Patent Classifications recently developed cooperatively by the European and US Patent Offices provide a new basis for mapping patents and portfolio analysis, and routines previously based on IPC for CPC are updated and used for rethinking various parameter choices.

Locating visual communication across disciplines: How visual instruction in composition textbooks differs from that in science-writing textbooks

This article shares results from a qualitative research project that examines the similarities and differences in how composition textbooks and science-writing textbooks address visual communication



Exploratory Social Network Analysis with Pajek

This second edition of the successful textbook on social network analysis integrating theory, applications, and network analysis using Pajek has a new chapter on random network models, for example, scale-free and small-world networks and Monte Carlo simulation.

Dynamic animations of journal maps: Indicators of structural changes and interdisciplinary developments

Using this indicator, the dynamics of the citation impact environments of the journals Cognitive Science, Social Networks, and Nanotechnology are animated and assessed in terms of interdisciplinarity among the disciplines involved.

Structural equivalence in a journal network

Concepts and techniques used in contemporary social network analysis are applied to a network of journals based on citation, supporting the idea of treating the journals of a discipline as a status‐role relational system.

Theories of citation?

The specific contexts represented in the modern citation can be deconstructed from the perspective of the cultural evolution of scientific communication.

“ Structuration ” by Intellectual Organization : The Configuration of Knowledge in Relations among Scientific Texts

Using aggregated journal-journal citation networks, the measurement of anticipation in empirical systems is examined in two cases of interdisciplinary developments during the period 1995-2005: (i)

Analysis of social networks is suggested as a tool for linking micro and macro levels of sociological theory. The procedure is illustrated by elaboration of the macro implications of one aspect of

Mental Models, Visual Reasoning and Interaction in Information Visualization: A Top-down Perspective

A top-down perspective of reasoning as model construction and simulation is presented, and the role of visualization in model based reasoning is discussed, and interaction can be understood as active modeling for three primary purposes: external anchoring, information foraging, and cognitive offloading.

‘Meaning’ as a sociological concept: A review of the modeling, mapping and simulation of the communication of knowledge and meaning

Analytical techniques such as semantic maps and the simulation of anticipatory systems enable us to operationalize the distinctions which Luhmann proposed as relevant to the elaboration of Husserl’s ‘horizons of meaning’ in empirical research.
