LinkedTV is pleased to contribute to the German DBPedia effort through the addition of hypernym discovery within Wikipedia article text. The “Linked Hypernyms Dataset” identifies the types of a resource through statistical type inference co-occurrence.
With this, a key problem for the German DBPedia dataset is being addressed: the sparsity of RDF type properties on DBPedia resources which makes SPARQL querying more difficult.
The new German DBPedia dataset now contains between 43 and 53% more rdf:type triples.
The same dataset is applied in the LinkedTV project to classify extracted entities from TV programming by type. This functionality is encapsulated in the service Targeted Hypernym Discovery (THD), developed and provided by our partner University of Economics Prague.
This was originally announced following the 2nd DBPedia Community meeting at http://de.dbpedia.org/node/30.
LinkedTV has been active this week in Berlin in the context of the Internationale Funk Ausstellung (IFA) – Europe’s answer to CES – and the parallel International Conference on Consumer Electronics (ICCE).
European households who purchase a new SmartTV will most likely have HbbTV capability, the European standard for hybrid broadcast-broadband content delivery. HbbTV has established itself today as a replacement for the old Teletext/Videotext that was once delivered within analog TV. It also provides access to online Mediatheken, the broadcasters TV archives. However, LinkedTV considers this only the beginning of what HbbTV is capable of offering viewers. HbbTV lets TV viewers access additional applications via the red button, however programme-specific applications are still limited. Combined with LinkedTV technology, a HbbTV capable SmartTV or Set Top Box could offer LinkedTV enrichments during supported TV programmes, accessed via the red button and then either displayed as overlays on the TV screen or pushed to a companion device such as the viewers tablet or laptop.

Meanwhile, our scientific coordinator Dr Lyndon Nixon of MODUL University presented the Linked Television vision, implementation and HbbTV prototype at the ICCE conference.
Finally, LinkedTV reiterated its commitment to the HbbTV 2.0 specification which is not yet launched in Consumer Electronics devices. Several key functionalities such as the ability to discover and connect to another screen or synchronize Internet content to broadcast TV are currently missing in HbbTV for LinkedTV to become a living room reality. Our prototype demonstrates the feasibility of the approach and we look forward to the next generation HbbTV devices that can support it!
A position paper on HbbTV 2.0 and LinkedTV considers this in more detail:
LinkedTV is pleased to be giving public demos of the Linked Television experience this month at both IFA Berlin and IBC Amsterdam!
During IFA, visit our partner Rundfunk Berlin Brandenburg (RBB) which is part of the German public broadcasters area in Hall 2.2. From the 5 to 10 September in the “Digitales Wohnzimmer” (digital living room) LinkedTV provides the demo of Interactive News – discover background information to the news you watch direct and interactive on your smart TV using LinkedTV innovation built on top of HbbTV technology!
Shortly after, the leading broadcasters exhibition IBC (12-16 September) will feature a dedicated LinkedTV living room set up in the FutureZone, Hall 8 Stand F42. Relax on the sofa with a tablet and discover watching TV while getting background and complementary information on your local screen providing you with a deeper understanding of both news and cultural heritage programmes, even across linguistic barriers!
LinkedTV can invite you with a free entry code for the IBC exhibition, just contact us with your name and company!
See you in September!
In the LinkedTV project, researchers are connecting TV content with the internet, so audiences can benefit from an more informative and personalised viewing experience.
Visitors to IBC’s Future Zone can see for themselves in a living room simulation. While watching a TV programme they can explore more information and content about concepts and topics via a companion app. The technology that makes this programme enhancement possible is targeted at broadcasters and OTT content providers.
“We will show this for two genres where further information exploration is a typical interest of viewers: a newscast by Rundfunk Berlin-Brandenburg and a documentary series of the Dutch TV station AVRO,” explained scientific co-ordinator Lyndon Nixon. “We think that viewer interest is sometimes lost or frustrated because it is not possible to easily find everything we see on TV: how do I Google for the painting I just saw on the wall behind the presenter when I don’t know the name of the artwork nor the artist?”
The institute is working with eleven partners from seven countries on LinkedTV. Software scans the contents of a show prior to its broadcast via speech analysis and image processing for topic-related content from the web.
“We want to seamlessly combine TV and the internet so that viewers can directly access background information about the current programme during the show, without having to spend a lot of time and effort themselves in searching for it,” said project manager Heike Horstmann.
Since the software provides a great number of unfiltered hits and semantic links, the researchers have developed methods to narrow down the results according to certain criteria.
“For example, content will be displayed only if it complies with laws for the protection of minors and for which the copyright is no problem,” Horstmann added. The editorial team adds the final touches, checking suggested content for relevance and eliminating any duplication from the hit list.
Parallel to the broadcast, the viewer then finds information sorted according to topic for each chapter of a TV programme. If desired, they can specify filter criteria that determine which content is displayed – defining topics of particular interest or hiding results for specific content. The software is also capable of learning and adjusts the offer of information to the user’s behaviour.
“If the viewer repeatedly accesses the weather report or information on a particular topic, for instance, this content will be displayed in a prioritised fashion,” said Horstmann. The viewer can view both broadcast and additional content directly on the screen of a connected TV or on another device with web access, such as a tablet or laptop.
The best approach would be to use two screens that are synchronised with each other in parallel. Generally, the show then runs on the television, while further content is displayed on the second screen.
