This position paper on expert finding presents a conceptual framework for the reuse and interlinking of existing, well-established vocabularies in the Semantic Web. Such a framework can be used to connect people with people, based on joint or complementing interests (e.g. the need to develop specific new or existing skills for upcoming projects). Driven by a requirement to find experts using th...

Data portability has become an important requirement on the Social Web. This paper describes how data and social network portability can be achieved by building upon existing Semantic Web developments such as SIOC and FOAF. The SIOC project provides a common format for expressing user-generated content in a machine-readable form and tools for import/export of this information, while the FOAF vo...

community is the main pillar of the urban body; and balance of social life in cities depends on preserving communities. during the twentieth century, the idea of residential-centered community has been offered in many modern theories and has been widely accepted for solving urban various problems such as management, social and human relations, health and welfare issues and aspects of meaning an...

E-Learning grows on the fertile soil of the Internet technologies; it fails, however, to reach their full potential. With new, emerging technologies of the second generation Internet there is even more to be captured and adopted: knowledge sharing with blogs, wikis, and social bookmarking services. In this article we argue that those technologies can be adapted to improve user experience in e-L...

This paper presents a framework for the reuse and extension of existing, established vocabularies in the Semantic Web. Driven by the primary application of expert finding, we will explore the reuse of vocabularies that have attracted a considerable user community already (FOAF, SIOC, etc.) or are derived from de facto standards used in tools or industrial practice (such as vCard, iCal and Dubli...

Since online Semantic Web applications are based on existing Web infrastructure, developing these applications could leverage experiences with and infrastructure of existing frameworks. These frameworks need to be extended to deal with the different nature of Semantic Web data. We introduce several extensions to the Ruby on Rails Web development framework to support Semantic Web application dev...

At present, there are many communities of blogs that are connected to each other in a formal or informal manner, through blogroll links, casual references from posts or via sites set up as aggregators for communities of interest. However, there is much information in such communities that could be formalised for use in searching, browsing and viewing of blog posts either locally or using third-...

While free-tagging classification is widely used in social software implementations and especially in weblogs, it raises various issues regarding information retrieval. In this paper, we describe an approach that mixes folksonomies and semantic web technologies in order to solve some of these problems, and to enrich information retrieval capabilities among blog posts. We first introduce the cor...

Despite negative perspectives on their consequences, gated communities continue to spread in cities due to structural reasons such as globalization and economic neo-liberalism. Hence, there is a need to seek for a way of achieving a balance and make these communities livable. Due to agreement with economic market perspectives, livability principles might offer a solution for mediating the socia...
