Rich Semantic Media for Private and Professional Users
- 2005
-
Rapport (refereegranskat)abstract
- This report presents the current state and future development potential oftechnologies that are relevant in developing new media products and servicesbased on content that is described with semantically rich metadata. It has beenwritten within the project "Rich semantic media for private and professionalusers". The project addresses two important trends and opportunities: utilisingsemantics in media products and combining commercial media content withuser created material.The report starts with a presentation of the framework for the project anddescribes three key demonstration ideas. The demonstrations explorecombining professional and private content and how this process benefitsfrom semantic support. The main focus of the project and this report is onsemantically supported media applications but the report briefly looks at theSemantic Web status in general and what kind of semantically supportedapplications there are already currently available.The big challenge in creating semantically supported media applications iscreating the necessary infrastructure, i.e. ontologies and content withmetadata. A formal language is needed for specifying the ontology, and therethe recently approved the Web Ontology Language (OWL) is an importantstep. However, there are still only few practical applications, so it is stillunclear how well this language can meet the requirements. Query language isanother important component, and there, SPARQL Query Language for RDF,is currently being defined.Creating metadata is very laborious, if made manually. Therefore, differentway of creating metadata must be utilised: metadata may be captured as a byproduct during the production and consumption processes, it may be createdexplicitly, or may be inferenced based on the content itself. Metadata creationis not in the focus of the project, but the main principles are briefly explained.Several existing media related vocabularies are presented in the report as wellas some publicly available ontologies. There is lack of publicly availablevocabularies and ontologies, and those that exist, such as IPTC, are oftenutilised only to limited extent. The report also lists several project that dealwith related issues.

Semantically supported media services with user participation : Report on the RISE-project
- 2006
-
Rapport (refereegranskat)abstract
- This publication presents the main results of the project "Rich Semantic Media for Private and Professional Users" (RISE). The background to the launch of the project was the identification of two important developments: the emergence of user-generated content and Semantic Web technologies. The goal was to study what kind of new opportunities semantic metadata and combining commercial media content with user-created material give to media companies and their suppliers for product and service development. The publication gives an overview on recent developments relating to utilising user-generated content and metadata in public Web applications, and an update on development on Semantic Web technologies related issues on their relevance to the application development made in the project. The project chose to explore research issues by building prototypes. Each of the prototypes is presented including a user scenario, implementation, results, discussion and future work. The StorySlotMachine is travelling related application, which allows users to make their own guidebooks to be used during the trip. After the trip users can make presentations combining their own photos and commercial content. Ontologies are used for automatic aggregation and to offer content that deals with the topic. The Remix Engine prototype is a Web-based video editing and compilation application that lets the user combine his or her own media with commercialmedia with the help of pre-made templates. The end product, a video, is composed of professional material that includes team logos, TV brands, advertisements, and so on. DiMaS is a Digital Content Distribution Management System for multimedia producers to publish their work on P2P file sharing networks. The system enables producers to insert content metadata, to manage intellectual property and usage rights, and to charge for the consumption. Applications like StorySlotMachine and RemixEngine could be built in connection to media archives, like news archives, or in connection to encyclopaedia, where the material is already modular. If and when users do the final aggregating and editing work themselves, the costs for offering content this way are not high after the initial investment in the tools and metadata have been made. Commercial media must be able to offer more value to the users than free services and utilising ontologies in makingservices more intelligent is one opportunity. There are still challenges for building this kind of services: A big issue in utilising semantic metadata and Semantic Web technologies is developing and maintaining ontologies. Another issue is adding semantic metadata to the content. Also legal issues like commercialisation of the content creation activity, intellectual property rights within the creators, the brand image of the content or the group, and managing the liability risks in content production need to be solved. If mediacompanies turn their content into more modular format and add semantic metadata to support reusability and active exploration of content they have more opportunities to create new consumer applications with rich user experience.

A Consumer-Device-Supported IPTV Network
- 2010
-
Ingår i: 2010 7TH IEEE CONSUMER COMMUNICATIONS AND NETWORKING CONFERENCE-CCNC 2010. ; , s. 896-900
-
Konferensbidrag (refereegranskat)abstract
- This paper concentrates on consumer devices and digital content consumption at home. We approach the topic from the perspective of our network operator partner and we ask how this operator can improve its content distribution from the current IPTV service. We propose a consumer device grid that is an integral part of the operator's IP network. Our proposal results in savings in the operator's data centers and in the home whilst offering more business opportunities for the operator and third party content providers.

Digital Content Networks : The Past, the Present and Decentralizing
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis presents a solution-oriented analysis of current issues in digital content distribution management and content networks. The findings support the view that the recent development in the area has created a few congestion points, both in content distribution and content business, that gather increasing technical, social, financial, and political influence in the world. As pointed out in the work, this is against the ideas of information democracy, network neutrality, and the original visions of the Internet and the World Wide Web. Furthermore, leading content companies are answering to the demands of the exponential content and traffic growth by continuously adding rather similar technological solutions, which increases the environmental problems, i.e., energy consumption and e-Waste, at the rate of this growth. The research time period of this dissertation matches with the emergence and rise of P2P file sharing networks that have introduced a new challenging way of distributing content. In this thesis, they are presented as the main comparison points and controversy to the centralized client-server architecture that dominates the content business. The essential question of this work is simply: How to build a better content network? To understand the meaning of "better" in this context and to state what is a better digital content network, it is necessary to understand existing solutions and their shortcomings. The thesis contributes an analytical framework of concepts and principles for the development of future content networks. How do we change the threat of P2P file sharing into an opportunity for professional content publishers? Actually, all the listed objectives in this work – under performance, privacy, network neutrality, e-commerce, and green computing – are societal in nature. Thus, the objective of this dissertation is to improve societal issues through understanding information technology and its closely related context. Through active participation in the file sharing scene, this work presents the development of content networks from computer networks capable of messaging between machines and systems to user networks where people share digital content. Easy copying to friends with rapidly changing user behavior have created a content platform where culture is evolving at an accelerated speed. Drawing from ten research projects and a score of technical prototypes, this thesis concludes that the P2P content sharing applications with their modern protocols effectively create a more advanced network as overlay than the underlying Internet can offer. The operators, who are excited about Internet technology for their networks, are actually limiting their possibilities right from the beginning. It is essential to distinguish between the development of the Internet and the development of large-scale content distribution network.

Konferensbidrag (refereegranskat)abstract
- Even if communication networks have become increasingly ubiquitous in nature offering connections from anywhere, often most both wireless connections and especially the fixed connection at home reach a data center at an operator facility. Operators struggle to facilitate the Internet growth. We approach the topic from the perspective of our network operator partner and we ask how this operator can improve its content distribution from the current IPTV service. We propose a consumer device grid that is an integral part of the operator's IP network. Our proposal results in savings in the operator's data centers and in the home whilst offering more business opportunities for the operator and third party content providers.
