Chapter
When we read a printed paper, document or book we sometimes come to points that we do not understand or where we feel important information is missing, or plain wrong, as we can show by examining a particularly reliable collection of data. Yet we can just shrug our shoulders, since contacting the source of the information is at least very cumbersom...

The Journal of Universal Computer Science is a monthly peer-reviewed open-access scientific journal covering all aspects of computer science, launched in 1994, so becoming twenty-five years old in 2019. In order to celebrate its anniversary, this study presents a bibliometric overview of the leading publication and citation trends occurring in the...
Article
Full-text available
We try to argue in this paper that the WWW is full of large collections of information, yet the reliability is always in doubt, independent if the information comes from a company server, an institution that was usually founded for some specific reason, or even a system like Wikipedia: certain aspects are often omitted, distorted or not dealt with...
Article
Full-text available
In this paper we describe lessons we have learnt from building up a webserver with reliable information over a period of ten years. We show how we have tried to overcome often encountered weaknesses and thus encourage the community to follow our suggestions. We also point out that much research and development work remains to be carried out.

“Enlightenment is man's release from his self-incurred tutelage“, says Kant. And continues: „Tutelage is man's inability to make use of his understanding without direction from another.“ The question of enlightenment is not only relevant in Kant's time, but also today. Might the enlightened, responsible and autonomous subject be endangered? Where a...

The increase in digitization of conventional books and other forms of print media suggests that digital or e-books are not a passing phenomenon. Present day digital library systems may have transformed the conventional processes into digital environment, however little development work has been done for the progression of traditional library busine...
Chapter
In this paper we discuss briefly a few aspects of some of the exciting new developments in information technology. We argue that most of ongoing activities and visions (if they become reality) are quite ambivalent: with positive and negative effects, with nobody really able to make credible forecasts. In Sect. 1, we first mention five issues. Three...

When studying a web page, the common problem is that users notice a mistake, or feel that some vital information is missing, or do not understand some explanation or wording. The possibly supplied list of frequently asked questions and answers is often not helpful, and trying to contact the web administration can be quite frustrating. In this note,...
Conference Paper
In this paper we argue that by using software that allows to add all kinds of interactions and media to digital books we can create what we will call interactive books (IBs for short) that are attractive to use for many purposes of information communication, be it as guide-book, handbook, manual or instructional material like in e-Learning systems....

Article
When we look up information in the WWW we hope to find information that is correct, fitting in quantity for our purposes and written at a level that we can understand. Unfortunately, very often one of the above criteria will not be met. A young person looking for information on some aspect of physics may well be frustrated when finding a complex fo...
Conference Paper
In this talk we will argue that developments in science will continue with increasing speed, opening completely new vistas. Why this is so is not just due to the usual trivial observations such as "developments are happening very fast and it seems even at accelerating speed". Rather, we will show a number of much deeper reasons, why nw developments...
Conference Paper
Digitized fact books are valuable sources of knowledge. Full-text search is a powerful tool to access such knowledge. However, it often delivers too many results for general queries. Therefore we propose an approach to find relevant data by extracting metadata relevant for each page and allow to search for pages on the basis of their metadata as al...
