According to the W3C Semantic Web Activity [1]: The Semantic Web provides a common framework that allows data to be shared and reused across appli- tion, enterprise, and community boundaries. This statement clearly explains that the Semantic Web is about data sharing. Currently, the Web uses hyperlinks to connect Web pages. The Semantic Web goes beyond that and focuses on data and envisions the creation of the web of data. On the Semantic Web, anyone can say anything about any resource on the Web. This is fully based on the concept of semantic - notations, where each resource on the Web can have an assigned meaning. This is done through the use of ontologies as a formal and explicit representation of domain concepts and their relationships [2]. Ontologies are formally based on description logics. This enables agents and applications to reason over the data when searching the Web, which has not previously been possible. Web 2. 0 has gradually evolved from letting the Web users play a more active role. Unlike the initial version of the Web, where the users mainly consumed content, users are now offered easy-to-use services for content production and publication. Mashups, blogs, wikis, feeds, interface remixes, and social networking/tagging s- tems are examples of these well-known services. The success and wide adoption of Web 2. 0 was in its reliance on social interactions as an inevitable characteristic of the use and life of the Web. In particular, Web 2.

Klappentext
Web 2.0 describes the trend in Web technology and design that aims to enhance creativity, information sharing, and, especially, collaboration among users. Semantic Web refers to the intelligent interaction among systems and applications on the Web by deploying ontologies, semantic annotation of Web content, and reasoning. Its ultimate goal is to make data understandable to computers, and thus open to far greater utility and manipulation. This special issue of AoIS presents cutting-edge research on both of these often opposed trends in computing and will support discussion on both the synergies and controversies inherent in the two technologies, while also considering what other technologies can contribute to both. Dramatic advances in service-oriented architectures, model-driven engineering, and Web mining technologies are but a few of the developments that might have a considerable impact on both Web 2.0 and Semantic Web, and they will all be covered in this volume.
