Semantically supported media services with user participation: Report on the RISE-project
2006 (English)Report (Refereed)
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.
