Abstract

The papers collected in this issue present a wide range of research that can be connected to the three main topics: the Web, Knowledge and Social Networks. Each and every of the papers touches at least two of these areas to a certain extent.

The evolution of Web infrastructure, methods of representing information published on, and functionalities available is discussed in World Wide Web on the Move and gives a good overview of different aspects of today's Web on the move. A number of these aspects are further investigated.

In particular weblogs, Wikipedia, Deep Web and Rich Internet Applications are discussed in subsequent articles. They are the phenomena that attract a lot (if not most of) interest of contemporary research in the area that was recently named by the Web originator – Tim Berners-Lee – the Web Science. Our Authors follow the trend by investigating: weblogs influence on Small and Medium Enterprises as means of conveying knowledge about management and the enterprise (paper by Alexander Stocker, Markus Strohmaier, and Klaus Tochtermann), Wikipedia as a knowledge-rich resource which might be used to annotate multimedia content (article by Angela Fogarolli and Marco Ronchetti), Deep Web as potentially ground-breaking information source, yet largely unexplored due to theoretical and practical limitations (contribution of Yang Wang and Thomas Hornung) and RIA as a new paradigm of exposing functionality on the Web combining state-of-the-art engineering paradigms and knowledge about an enterprise (for Kay-Uwe Schmidt, Roland Stuehmer and Ljiljana Stojanovic this knowledge comes in a form of business rules).

Social aspect of the Web Science was also studied in this issue. The work of Celine Van Damme, Tanguy Coenen and Eddy Vandijck describes the method of using socially created folksonomies to formalize enterprise knowledge into an ontology. Raf Guns exercises well known (although not entirely standard) social network analysis tools on social Semantic Web. Paolo Massa, Kasper Souren, Martino Salvetti and Danilo Tomasoni propose an open platform to exchange trust metrics and algorithms to compute them, which are crucial for social network adoption and prosperity.

Finally, the works that focus on knowledge subject include the paper by Dimitris Bibikas and his colleagues, that builds on a case study to propose novel approach to knowledge management within enterprise using Web paradigms, as well as the article by Alsayed Algergawy, Eike Schallehn and Gunter Saake describing fuzzy approach to solve a well known (and hard) knowledge representation matching problem in the context of Deep Web sources.

Following the traditional division into theoretical and applied approaches, in this issue there are papers that present theoretical developments and new methods (as in Fuzzy Constraint-Based Schema Matching Formulation, Discovering Semantics In Multimedia Content Using Wikipedia, Deep Web Navigation By Example) or applied research in the form of blueprints for systems design and architectures (like From Business Rules To Application Rules In Rich Internet Applications), as well as empirical evidences (Unevenness In Network Properties On The Social Semantic Web, Studying Knowledge Transfer With Weblogs in Small and Medium Enterprises: An Exploratory Case Study and A Sociotechnical Approach To Knowledge Management In The Era Of Enterprise 2.0: The Case Of Organik). As usual there are border cases, like Deriving A Lightweight Corporate Ontology Form A Folksonomy: A Methodology And Its Possible Applications and Trustlet, Open Research On Trust Metrics, where Authors discuss both the method and its possible application scenarios.

Overall, the wide coverage of paper topics shows clearly, that the contemporary Web is both a field to apply old and well tested techniques to new problems, and a fertile environment for innovation. We sincerely hope that our Readers find among the work gathered in this issue an inspiration for new inventions and theories.
