The Web Science Observatory
No full textTo understand and enable the evolution of the Web and to help address grand societal challenges, the Web must be observable at scale across space and time. That requires a globally distributed and collaborative Web Observatory
Web evolution and Web Science
No full textThis paper examines the evolution of the World Wide Web as a network of networks and discusses the emergence of Web Science as an interdisciplinary area that can provide us with insights on how the Web developed, and how it has affected and is affected by society. Through its different stages of evolution, the Web has gradually changed from a technological network of documents to a network where documents, data, people and organisations are interlinked in various and often unexpected ways. It has developed from a technological artefact separate from people to an integral part of human activity that is having an increasingly significant impact on the world. This paper outlines the lessons from this retrospective examination of the evolution of the Web, presents the main outcomes of Web Science activities and discusses directions along which future developments could be anticipated
A generic component for managing service roles
No full textThere are a number of architectures that describe how service providers can provide telecommunications services to their customers. Architectures like TINA address service control and service management issues for communication exchanges among human service users. n this paper we point out the importance of role-based exchanges in a telecommunications environment and we present a generic component that provides role management. We describe how this component was implemented and integrated in a TINA-like environment. We also describe why a role can be modelled as a mobile entity and how role mobility relates to role management. Finally, some conclusions are drawn
A service engineering approach to inter-domain TMN system development
No full textThe deployment of service management systems in a multi-service environment opens a whole area of issues. Requirements for openness and reusability can be satisfied by following a service engineering approach where the service management functionality is decomposed to reusable service components. Such an approach that was based on TMN technology is presented in this paper and conclusions are drawn about the potential of other available technologies with regard to service management
Offering Role Mobility in a TINA Environment
No full textThis paper presents the concept of role mobility and the value of role mobility in an open service environment. We outline the aspects of role management and role mobility and we describe an open, reusable component for role management. Then, we show how this component can be deployed in a TINA environment with a minimum number of changes to the TINA service architecture
Integrating TINA into an Internet-Based Services Market
No full textThe deregulation of the telecommunication industry is providing the basis for a competitive, open market in telecommunications services. The TINA Consortium is developing a software architecture that aims to support both communication and information services in an open services market. This paper examines the suitability of TINA for use in an open services market based on Internet technology. An implementation of a composite, IP-based service that uses features of the TINA Service Architecture is presented, and the implications for the wider integration of TINA and the Internet in the delivery of open services are discussed
The role of institutional repositories in addressing higher education challenges
No full textOver the last decade, Higher Education around the world is facing a number of challenges. Challenges such as adopting new technologies, improving the quality of learning and teaching, widening participation, student retention, curriculum design/alignment, student employability, funding and the necessity to improve governance are considered particularly in many literature. To effectively operate and to survive in this globalization era, Higher Education institutions need to respond those challenges in an efficient way. This paper proposes ways in which institutional data repositories can be utilized to address the challenges found in different literature. Also we discuss which repositories can be shared across the institutions and which need not to be shared in order to address those challenges. Finally the paper discusses the barriers to sharing Higher Education repositories and how those barriers can be addressed
Evaluating a Web-Based Information System for Managing Master of Science Summer Projects
No full textWe describe the design of a web-based information system for monitoring MSc summer projects in the School of Electronics and Computer Science at the University of Southampton, and a mixed method quasi-experimental study involving 290 MSc project students, 19 monitors, and 69 supervisors in electronics and computer science, using the system over a period of 17 weeks. Statistically significant results presented here are: Students making heavy use of the system achieved higher marks on their project dissertation, while no such correlation was found with marks for other parts of their MSc. Likewise, student's monitor activity is significantly correlated with their own activity and dissertation mark. These results suggest that educational information and project management systems positively affect student achievement and academic staff involvement is crucial for these systems to be successful. Future work includes a more detailed analysis of success factors and their impact on student performance
Taking the relationship to the next level: a comparison of how supporters converse with charities on Facebook and Twitter
No full textSocial media provide a unique opportunity for charities to reach a large audience with whom they can engage in productive two-way conversations. This abstract reports findings from a study that seeks to determine the extent to which these conversations occur, and whether they differ between Facebook and Twitter. Differences arise showing that Facebook receives more conversations in response to the charities' own posts. However, on Twitter more comments are made per each engaged supporter, which could represent more unsolicited discussion that provides an alternative type of value
