Our technique can be also used for quality control in UMTS environments, exploiting the tracing watermarking recently introduced in literature. In this work, we use the transmitted video-sequences to monitor the QoS in a videoconference call. The video-sequence of every active user travels on the communication link, one time as video (transparent mode), one time as watermark (hidden mode) describing a boomerang trajectory. The results obtained through our simulation trials confirm the validity of such approach. In fact, the advantages of distributing the management process are (i) an easier and more precise localization of the cause of QoS problems, (ii) a better knowledge of local situations, (iii) a lower complexity for a single QoS agent and (iv) an increase in possible actions. http://www.mdpi.com/1999-5903/2/1/60 Sun, 07 Mar 2010 23:00:01 GMT Future Internet 2010-03-08 2 1 Article 60 73 1999-5903 Dynamic QoS Evaluation of Multimedia Contents in Wireless Networks by “Double-Boomerang” Watermarking 2010-03-08 doi:10.3390/fi2010060 Francesco Benedetto Alberto Curcio Gaetano Giunta http://www.mdpi.com/1999-5903/2/1/41 Currently, there is much talk of Web 2.0 and Social Software. A common understanding of these notions is not yet in existence. The question of what makes Social Software social has thus far also remained unacknowledged. In this paper we provide a theoretical understanding of these notions by outlining a model of the Web as a techno-social system that enhances human cognition towards communication and co-operation. According to this understanding, we identify three qualities of the Web, namely Web 1.0 as a Web of cognition, Web 2.0 as a Web of human communication, and Web 3.0 as a Web of co-operation. We use the terms Web 1.0, Web 2.0, Web 3.0 not in a technical sense, but for describing and characterizing the social dynamics and information processes that are part of the Internet. http://www.mdpi.com/1999-5903/2/1/41 Thu, 18 Feb 2010 23:00:01 GMT Future Internet 2010-02-19 2 1 Article 41 59 1999-5903 Theoretical Foundations of the Web: Cognition, Communication, and Co-Operation.

However, files in widespread use, such as HTML documents, usually exhibit high redundancy levels, caused by code-generation programs. Such redundancy may be removed by means of optimization software. Redundancy removal, if applied selectively, enables information hiding. This work introduces Selective Redundancy Removal (SRR) as a framework for hiding data. An example application of the framework is given in terms of hiding information in HTML documents. Non-uniformity across documents may raise alarms. Nevertheless, selective application of optimization techniques might be due to the legitimate use of optimization software not supporting all the optimization methods, or configured to not use all of them. http://www.mdpi.com/1999-5903/2/1/30 Sun, 14 Feb 2010 23:00:01 GMT Future Internet 2010-02-15 2 1 Communication 30 40 1999-5903 Selective Redundancy Removal: A Framework for Data Hiding 2010-02-15 doi:10.3390/fi2010030 Ugo Fiore http://www.mdpi.com/1999-5903/2/1/16 This paper deals with an autonomous cognitive network management architecture which aims at achieving inter-network (horizontal) and inter-layer (vertical) cross-optimization. The proposed architecture is based on the so-called Cognitive Managers transparently embedded in properly selected network nodes. The core of each Cognitive Manager are the so-called thinking modules, which are in charge of taking consistent and coordinated decisions according to a fully cognitive approach. The thinking modules potentially avail of information coming from both the transport and the service/content layers of all networks and, based on all this inter-layer and inter-network information, take consistent and coordinated decisions impacting the different layers, aiming at the overall inter-layer, inter-network optimization. http://www.mdpi.com/1999-5903/2/1/16 Thu, 21 Jan 2010 23:00:01 GMT Future Internet 2010-01-22 2 1 Article 16 29 1999-5903 A Fully Cognitive Approach for Future Internet 2010-01-22 doi:10.3390/fi2010016 Francesco Delli Priscoli http://www.mdpi.com/1999-5903/2/1/1 Searching names of persons, families, and organizations is often difficult in online databases because different persons or organizations frequently share the same name and because a single person’s or organization’s name may appear in different forms in various online documents. Databases and search engines can use metadata as a tool to solve the problem of name ambiguity and name variation in online databases. This article describes the challenges names pose in information retrieval and some emerging name metadata databases that can help ameliorate the problems. Effective name disambiguation and collocation increase search precision and recall and can improve assessment of scholarly work. http://www.mdpi.com/1999-5903/2/1/1 Mon, 04 Jan 2010 23:00:01 GMT Future Internet 2010-01-05 2 1 Article 1 15 1999-5903 Metadata for Name Disambiguation and Collocation 2010-01-05 doi:10.3390/fi2010001 Jeffrey Beall http://www.mdpi.com/1999-5903/1/1/59 The evolution of the Web over the past few years has fostered the growth of a handful of new technologies (e.g. Blogs, Wiki’s, Web Services). Recently web mashups have emerged as the newest Web technology and have gained lots of momentum and attention from both academic and industry communities. Current mashup literature focuses on a wide array of issues, which can be partially explained by how new the topic is. However, to date, mashup literature lacks an articulation of the different subtopics of web mashup research. This study presents a broad review of mashup literature to help frame the 1subtopics in mashup research. http://www.mdpi.com/1999-5903/1/1/59 Mon, 21 Dec 2009 23:00:01 GMT Future Internet 2009-12-22 1 1 Review 59 87 1999-5903 Mashups: A Literature Review and Classification Framework 2009-12-22 doi:10.3390/fi1010059 Brandon Beemer Dawn Gregg http://www.mdpi.com/1999-5903/1/1/47 This paper describes a follow-up Web 2.0 approach to a technology enhanced master course for students of Graz University of Technology. The lecture “Social Aspects of Information Technology” has a long tradition for using new didactical scenarios as well as modern e-Learning technologies. After using a blogosphere one year ago, this year microblog channels helped to expand the traditional lecture. Students choose (on a voluntary basis) whether they want to participate in a blogging/microblogging group instead of using conventional methods called Scientific Writer/Scientific Reviewer. This study addresses the question whether this method can change the learning outcome into a more reflective one. Furthermore, peer-reviewing groups judge the quality of essays and blog contributions. In this paper we examine if microblogging can be an appropriate technology for assisting the process. This publication comes to the conclusion that an amazing potential and a new way to work with information is opened when using microblogging. Students seem to be more engaged, reflective and critical in as much as they presented much more personal statements and opinions than years before. http://www.mdpi.com/1999-5903/1/1/47 Tue, 17 Nov 2009 23:00:01 GMT Future Internet 2009-11-18 1 1 Article 47 58 1999-5903 Can Weblogs and Microblogs Change Traditional Scientific Writing? 2009-11-18 doi:10.3390/fi1010047 Martin Ebner Hermann Maurer http://www.mdpi.com/1999-5903/1/1/28 Metadata have long been recognised as crucial to geospatial asset management and discovery, and yet undertaking their creation remains an unenviable task often to be avoided. This paper proposes a practical approach designed to address such concerns, decomposing various data creation, management, update and documentation process steps that are subsequently leveraged to contribute towards metadata record completion. Using a customised utility embedded within a common GIS application, metadata elements are computationally derived from an imposed feature metadata standard, dataset geometry, an integrated storage protocol and pre-prepared content, and instantiated within a common geospatial discovery convention. Yielding 27 out of a 32 total metadata elements (or 15 out of 17 mandatory elements) the approach demonstrably lessens the burden of metadata authorship. It also encourages improved geospatial asset management whilst outlining core requisites for developing a more open metadata strategy not bound to any particular application domain. http://www.mdpi.com/1999-5903/1/1/28 Mon, 09 Nov 2009 23:00:01 GMT Future Internet 2009-11-10 1 1 Article 28 46 1999-5903 A Method for Automating Geospatial Dataset Metadata 2009-11-10 doi:10.3390/fi1010028 James K. Batcheller Bruce M. Gittings Robert I. Dunfey http://www.mdpi.com/1999-5903/1/1/14 The common understanding of e-learning has shifted over the last decade from the traditional learning objects portals to learning paradigms that enforces constructivism, discovery learning and social collaboration. Such type of learning takes place outside the formal academic settings (e.g., seminars or lectures) where a learning environment is created by using some kind of web application mashup tools. The use of these mashup tools moves the learning environment further away from being a monolithic platform towards providing an open set of learning tools, an unrestricted number of actors, and an open corpus of artifacts, either pre-existing or created by the learning process – freely combinable and utilizable by learners within their learning activities. However, collaboration, mashup and contextualization can only be supported through services, which can be created and modified dynamically based on middlewares to suit the current needs and situations of learners. This article identifies middlewares suitable for creating effective personal learning environment based on Web 2.0 mashup tools. This article also proposed a general framework for constructing such personal learning environments based on Ambient Learning realized by learning agents and the use of Enterprise Mashup servers. http://www.mdpi.com/1999-5903/1/1/14 Tue, 04 Aug 2009 22:00:01 GMT Future Internet 2009-08-05 1 1 Article 14 27 1999-5903 Identifying Middlewares for Mashup Personal Learning Environments 2009-08-05 doi:10.3390/fi1010014 Jinan Fiaidhi Sabah Mohammed Lyle Chamarette David Thomas http://www.mdpi.com/1999-5903/1/1/1 In 1995 technology analyst Gartner [1] developed a hype cycle model for the adoption of technology. The cycle comprises five stages from the initial technology trigger through to a final plateau of productivity along a with a peak of inflated expectations, a tough of disillusionment and the slope of enlightenment. The hype cycle is notable technique for plotting and identifying waves of innovation and hype in technology and digital communications. Yet, from where we stand, we can see the waves of innovation becoming increasingly shorter, the troughs less deep and the peaks of expectations higher. The read-write revolution, that is arguably known as Web 2.0, has transformed our experience of using the Internet from a source of information to a means of communication and participation. It has introduced mirror worlds, the cloud, wikitecture, social shaping, connected places, folksonomies and many other terms that I am sure many of us have used in recent grant applications and papers. This is the here and now, all of these technologies are past the technology trigger point and rising up the peak of inflated expectations with a few already heading towards the trough before becoming mainstream and approaching mass adoption.

Two case studies of recent initial teacher training programmes are reviewed where blogs and wikis were blended to create new virtual learning spaces. In two separate studies, students offer their views about using these tools, and reflect on the strengths and weaknesses of this approach. There is also discussion about aggregation of content and a theorization of how community and personal spaces can create tension and conflict. A new ‘learning spaces’ model will be presented which aids visualization of the processes, domains and territories that are brought into play when content and Web 2.0 tools are mashed up within the same space. http://www.mdpi.com/1999-5903/1/1/3 Sun, 12 Jul 2009 22:00:01 GMT Future Internet 2009-07-13 1 1 Article 3 13 1999-5903 Learning Space Mashups: Combining Web 2.0 Tools to Create Collaborative and Reflective Learning Spaces 2009-07-13 doi:10.3390/fi1010003 Steve Wheeler
