Todays WWW consists of more than just information. The WWW provides a large number of services, which often require identification of it's users. This has lead to the fact that today users have to maintain a large number of different credentials for different websitesdistributed or shared identification system are not widely deployed. Furthermore current authorisation systems requires strict centralisation of the authorisation procedure-users themselves are usually not enabled to authorise their trusted friends to access services, although often this would be beneficial for services and businesses on the Web. In this article we present D-FOAF, a distributed identity management system which deploys social networks. We show how information inherent in social networks can be utilised to provide community driven access rights delegation and we analyse algorithms for managing distributed identity, authorisation and access rights checking. Finally we show how the social networking information can be protected in a distributed environment.
Abstract. In recent years more and more information has been made available on the Web. High quality information is often stored in dedicated databases of digital libraries, which are on their way to become expanding islands of well organized information. However, managing this information still poses challenges. The Semantic Web provides technologies that are about help to meet these challenges.In this article we present JeromeDL, a full fledged open-source digital library system. We exemplify how digital library content management can benefit from the Semantic Web. We define and evaluate browsing and searching features. We describe how the semantic descriptions of resources and users profiles improve the usability of a digital library. We present how digital libraries can be interconnected into one heterogeneous database with use of semantic technologies.
In this paper, we present a distributed Web service discovery architecture that is designed to be reliable, flexible and scalable. The architecture is based on the concept of distributed shared space and intelligent search among a subset of spaces. It allows the publishing of Web service descriptions as well as to submit requests to discover the Web service of user's interests. The Web service capabilities and the user requests (goal) are described using a Resource Description Framework (RDF) data model. The architecture supports integration of applications running on different resource specific devices. An application scenario is presented to illustrate the functionality of the proposed architecture.
a b s t r a c tMassive Open Online Courses (MOOCs) are becoming an essential source of information for both students and teachers. Noticeably, MOOCs have to adapt to the fast development of new technologies; they also have to satisfy the current generation of online students. The current MOOCs' Management Systems, such as Coursera, Udacity, edX, etc., use content management platforms where content are organized in a hierarchical structure. We envision a new generation of MOOCs that support interpretability with formal semantics by using the SemanticWeb and the online social networks. Semantic technologies support more flexible information management than that offered by the current MOOCs' platforms. Annotated information about courses, video lectures, assignments, students, teachers, etc., can be composed from heterogeneous sources, including contributions from the communities in the forum space. These annotations, combined with legacy data, build foundations for more efficient information discovery in MOOCs' platforms. In this article we review various Collaborative Semantic Filtering technologies for building Semantic MOOCs' management system, then, we present a prototype of a semantic middle-sized platform implemented at Western Kentucky University that answers these aforementioned requirements.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
