Current affordances in educational and workplace settings have much to do with managing and making use of complex knowledge and a diversity of information resources. Knowledge and information visualizations are used to make structures of knowledge and information apparent, as well as to help users coping with complex tasks and ill-structured subject matter. Knowledge visualization aims at assisting the users in learning and problem solving. Information visualization aims at helping users to explore large amounts of data by making use of the human cognitive ability to see patterns and by using interactive filtering techniques. Both approaches suffer from shortcomings resulting from the limitations of their conceptual rationale, as well as those of the representational techniques and methods used for visualization. These shortcomings may not easily be overcome with means provided by the individual approaches alone. It is suggested that synergies may be revealed when ideas and technologies from both fields are brought together. Along these lines, the Special Issue draws attention to digital concept mapping as a bridging technology to overcome shortcomings in visualizing knowledge and information. This introductory paper serves the purpose of outlining the rationale and goals of the special issue. It provides a preview of the relevance of each paper's contributions to the central theme of this issue.

First Time

Over the past decade, the issue of uncontrolled growth of unsystematic information in Internet has remained acute for the scientific community. The problem of finding relevant information related to the distribution and autonomy of scientific information resources remains. A priority in the field of centralized access to the key scientifically significant sources of information is the creation of a united information space (UIS). The study aims to identify the main models to form systems integrating distributed information resources, and as a result to determine the structure of UIS formation in a research library. Two models were considered and analyzed in the study: a meta-aggregator and an integrated electronic library. During the analysis, elements, structure and a set of functions for users and employees of a research library are revealed for each model. The study allowed the drawing of the following conclusions:• The choice of a model for the UIS formation depends mostly on the formulation of tasks, the solution of which is the purpose of creating a system, as well as on the technological potential of the organizations involved in the process.•Multifunctionality of the system allows simultaneous use of the above-mentioned formation models.• Adding the element of interactivity to the structure of UIS of the research library will allow timely monitoring of changes in the information needs of scientists, reduction of time, labor and financial costs of both the library and a user. The article presents the criteria for choosing a model. For the first time the optimal effective structure of the UIS in the research library is described.

The Speckled Computing project is a large multisite research project based in Scotland, UK. The aim of the project is to investigate, prototype, and produce tiny (1mm3) computational devices, called Specks, that can be configured into wireless sensor networks, called SpeckNets. Our particular interest is in how people might interact in such environments, what interaction tools they require, and what characteristics are required to be provided by the operating system of the Specks. Interaction in these environments places the human physically inside an information space. At one time, the human may be interacting with one Speck, at another with a hundred, and at another with several thousand. Moreover, the Specks themselves have no input method, apart from their sensors, and no output display. We explore these issues through taking some theories of distributed information spaces, some design principles from information visualization, and report on some empirical studies of prototypes and simulations that have been developed.

The Web

- We examined the consequences of a visualization pattern often chosen by web sites which show textual information within the web pages and the related iconic information within pop-up windows. The information visualization in pop-up windows aims to integrate text and pictures but makes difficult the analysis of both information resources. We conducted an experiment in which 80 participants read on a computer screen a text with embedded graphs either near (to the related textual information) or far (from it), plus graphs were integrated in the text or within pop-up windows. The reading behaviour of participants was observed to establish who, among them, examined the graphs and who did not. The recall for textual and iconic information was measured using a recall questionnaire. Our pattern of data shows a student's tendency to ignore graphs, in particular when they are visualized in pop-up windows. These results are confirmed by interviews to undergraduate students who analyzed the same materials using thinking aloud method.
