The paper “Semantic Copyright Management of Media Fragments” will be presented at the DATA 2013 conference next July 30th. The paper, authored by Roberto García, David Castellà and Rosa Gil from MediaMixer partner Universitat de Lleida, describes the proposal of the European project MediaMixer for media reuse. Media fragments and the management of their rights, beyond simple access control, are the centrepieces of this proposal. The paper focuses on the latter, for which it is necessary to provide highly expressive rights representations that can be connected to media fragments. Ontologies provide enough expressive power and facilitate the implementation of copyright management solutions that can scale in such a scenario. The proposed Copyright Ontology is based on Semantic Web technologies, which facilitate implementations at the Web scale, can reuse existing recommendations for media fragments identifiers and interoperate with existing standards. To illustrate these benefits, the papers presents a use case where the ontology is used to enable copyright reasoning on top of DDEX data, the industry standard for information exchange along media value chains. Attend DATA2013 and learn more, and get the background information and MediaMixer tutorial via our community.



One of the challenges faced by the MediaMixer consortium is that there is no pre-existing industry “buzzword” or well-defined market segment for “semantic multimedia”, or combining “the web” (the application of fragment URIs and linked data in particular) across the broadcast and media value chain. MediaMixer’s community represents part of the solution, by providing a focal point where these techniques may be brought together, drawing together common strands from more established segments.

IBC is the foremost media conference for the broadcast-related industry. The “Booster” was the first event of its type for IBC, promoting interactive formats designed to address the need for delegates from all areas of the media value chain associated with broadcast, to better share insights and information regarding their innovations and future predictions. MediaMixer is predicated on the assumption that semantic multimedia and specific W3C web standards being important in the future, so it was beneficial to the project and industry attendees that MediaMixer was visible at the event. Most presentations required audience participation. The two themes, “Cloud” and “Connecting Content”, are both umbrella themes that broadly encompass the touch points the industry has with MediaMixer’s topics.

MediaMixer is pleased to have been Silver Sponsor at this event and our colleague Martin Dow had the pleasure to engage with attendees on the MediaMixer offer and benefits of community membership. Martin will speak again about MediaMixer at a FOCAL Metadata conference in London on July 10, 2013.


This month, June 2013, MediaMixer partner Acuity Unlimited will be present at two media events, the Sheffield Doc/Fest on June 12 and the IBC London Technology Booster on June 25-26. Meet our representative Martin Dow to learn more about MediaMixer’s offer to community members:

  • the Crossover Interactive Summit focuses on Transformers, people who want to change the world and have moved from one platform to another to do so: filmmakers creating apps, doc producers moving to social platforms, app designers making hardware and video game developers making physical objects. Acuity can explain web standards-oriented media technologies to enable diverse possibilities for media access and reuse across multi-platform production contexts.
  • IBC’s inaugural London based conference will cover today’s two hottest technology topics – Connected Content and The Cloud. Such “new technologies for connecting content to consumers” include what MediaMixer promotes, and Acuity can explain MediaMixer’s semantic and web standards-oriented approach to fine-grained Connected Content, and the significant role played by linked data on the web to media management, rights management and metadata enrichment in the Cloud.

With the title “Advanced Methods and Tools for Web-based Education”, this event at the OCWC Global conference brought together students, researchers and other professionals from diverse technological, social and educational backgrounds to understand the ways in which new technologies are shaping the future of education. Organised by FP7 projects such as transLectures, Xlike and Mediamixer,  this one-day event was held immediately prior to the main conference in Bali, Indonesia and was by all means very successful.

The lecture room was completely full hosting 27 attendees from 1) APTIKOM, an association of colleges and universities in Indonesia that offer educational programs in computing, information systems and technology – out of 2,750 higher education institutions in the country, approximately 750 of them are the members of APTIKOM, with a collective student body of 600,000 people – 2) the OpenCourseWare Consortium, 3) the Ministry of Communication and Informatics of Indonesia, and 4) the Ministry of Education and Culture of Indonesia. The speakers were Marko Grobelnik (JSI), Mitja Jermol (JSI) and Colin de la Higuera (Uni. Nantes).

Since the workshop was directed towards showing the participants an overview of the European state-of-the-art on new-media solutions, the workshop presented 1) short introduction to machine learning, machine translation language technologies, 2) an introduction to advanced large scale data analytics (big data), 3) language-agnostic cross-lingual services, and 4) technologies to monitor and aggregate knowledge that is currently spread across different domain collections, and granular level media fragment re-purposing and re-mixing that may be pertinent to setting up an e-learning or open education project.

Mediamixer fits into this workshop scenario by providing a community that can help these practitioners that are opening up to online educational videos, thereby expanding the consumer base of any given video for sharing and re-purposing. One of the main facilitator being the exponential growth of Internet access in Indonesia with 25% penetration and 80 million users – all high consumers of digital online content,mostly via smart devices. This uptake is also present and visible in the audio-visual market.

The videos, presentations and follow up news to the workshop will be posted on the Knowledge 4 All Foundation Ltd. website (http://www.k4all.org/?q=node/1093) for further consumption.


MediaMixer will be presented at the Metadata Developer Network Workshop 2013 (http://tech.ebu.ch/MDN2013), organised by the European Broadcasters Union. June 5-6 2013, Geneva, Switzerland. The talk “MediaMixer: facilitating media fragments mixing and its rights management using semantic technologies” to be given by Roberto García of the University of Lleida will focus on how Media Fragments will be also linked to rights information based on a copyright ontology, which integrates licenses, policies and rights expressions based on existing standards like DDEX, ODRL or MPEG-21.


MediaMixer has co-supported the first worldwide workshop on Linked Media (LiME) together with the EU project LinkedTV at the World Wide Web Conference (WWW2013). The workshop has promoted for the first time to the international Web community the vision and goals of “Linked Media”. MediaMixer promotes technology for eased publication and re-use of fragments of audiovisual media across the Web, which can be part of the Linked Media vision. Project co-ordinator Lyndon Nixon held a keynote talk at the workshop outlining his goals for making Linked Media a reality – the keynote slides can be seen at http://de.slideshare.net/linkedtv/www-linked-media-keynote

MediaMixer partner JSI is pleased to announce a special workshop on “Advanced Methods and Tools for Web-based Education” one day before the main OCWC Global Conference 2013. OCWC – the Open CourseWare Consortium – is a collaboration of more than 200 higher education institutions and associated organizations from around the world creating a broad and deep body of open educational content using a shared model. The mission of the OpenCourseWare Consortium is to advance education and empower people worldwide. The workshop will permit conference attendees to learn about, among others, technologies for granular level media fragment re-purposing and re-mixing that may be pertinent to setting up an e-learning or open education project.

 


VideoLectures.Net and the MediaMixer project have launched a challenge at the 21st ACM International Conference on Multimedia. This requires participants to develop tools for automatic segmentation of videos that could then be implemented in the video library. For more information and submission guidelines visit the official website. The finalists will be published in the proceedings and presented in a special event during the conference in Barcelona.

Call for participation now published

VideoLectures.NET mostly hosts lectures 1 to 1.5h long linked with slides and enriched with metadata and additional textual contents. With automatic temporal segmentation and annotation of the video we would gain on efficiency of our video search engine and be able to provide users with the ability to search for sections within a video, as well as recommend similar content. This would mean that the challenge participants develop tools for automatic segmentation of videos that could then be implemented in VideoLectures.NET.

Evaluation

There will be 3 criteria for evaluation:

1. The quality of segmentation and annotation. The key criteria for evaluation will be the quality of the segmentations and annotations* that are extracted from a particular video. Goal: most clearly separated and detailed automatic description of why a segment is a new segment. For the annotations of the segments we do not have a specified vocabulary. Participants should annotate the segments with descriptive labels that allow us to differentiate between various segments and retrieve subsets of them, e.g. using labels of actions (presentation, Q&A, etc.) or also labels based on presentation (sub-)topics.

2. Service effectiveness. How to increase the searchability of the content (when searching for specific content using a search engine, or while browsing)? Goal: quality of annotations used for searching; duration of the processing in time; amount of processed data.

3. Efficiency of the underlying algorithm. Goal: ease of integration, processing speed.

Dataset

Videos will be provided. Participants are also free to use additional datasets for testing their approaches, in addition to the videos provided by the Challenge organizers.
