LinkedTV presented improved results at the 2014 NIST #TRECVID Workshop for Multimedia Event Detection, Multimedia Event Recounting and Semantic Indexing

LinkedTV partner CERTH participated this year to the Semantic Indexing (SIN), Multimedia Event Detection (MED) and Multimedia Event Recounting (MER) tasks of the TRECVID International Benchmarking Activity. Significantly improved results were attained, compared to last year’s participation to the same tasks, verifying the significance of the work carried out in LinkedTV for solving hard video analysis problems.

One of the highlights of LinkedTV’s participation was the new, very fast machine learning method for big data problems that CERTH developed. Tested in large-scale multimedia event detection problems, this new method produces better results than both Kernel- and Linear-SVMs, while its training is one or two orders of magnitude faster than Linear-SVMs (and even more so compared to Kernel-SVMs). The use of this new approach in the Multimedia Event Detection problem was highlighted with an oral presentation at the TRECVID Workshop (check out our slides on this: http://www.iti.gr/~bmezaris/downloads/CERTH_TRECVID14_MED_Presentation.pdf ).

LinkedNews application @bid_dimad after winning Design Prize; will be exhibited in Madrid and then Latin America.

At the Ibero American Biennial of Design (BID) in Madrid, researchers Lilia Perez and Michiel Hildebrand from the Centrum Wiskunde & Informatica (CWI) in Amsterdam, have been awarded a honorary mention in the category Digital Design for the concept and interaction design of Linked TV News. Linked TV News is a second screen companion for watching the news based on semantic web technologies.  

The project was selected out of six hundred submissions and reached the top 5 in its category. As a consequence Linked TV News will be featured in the international exhibition of the Biennial that will be shown from 25 November 2014 to 28 February 2015 in Madrid. Following that, the collection will tour throughout Spain and several Latin American countries to be shown in design and art museums and venues.

@CERTH releases new version (V1.4) of their video temporal segmentation software for #videoanalysis

LinkedTV partner CERTH (Thessaloniki, Greece) just publicly released version 1.4 of its software for the automatic temporal segmentation of videos into shots and scenes. This release uses exclusively CPU-based processing and the analysis is accelerated by invoking multi-threading / multi-processing operations of the Intel OpenMP runtime library, making the whole video analysis process about 7 times faster than real-time processing on an i7 PC.

The development and release of this software was supported by EU research projects LinkedTV and MediaMixer (http://www.mediamixer.eu/). Read more about research on hypervideo analysis in LinkedTV as well as check out several video analysis demonstrators.

The software is available for download at http://mklab.iti.gr/project/video-shot-segm

Report from #MediaEval2014 – LinkedTV in Search & Hyperlinking of Multimedia Content

LinkedTV took part for the second time in the MediaEval Search and Hyperlinking task. The methodology developed by project partners produced interesting results which confirmed that LinkedTV Hyperlinking technologies are strong performers. More details on the LinkedTV approach are available here.

In MediaEval 2014, LinkedTV in collaboration with other research projects also supported the organization of the “Social Event Detection in Web Multimedia” (SED) task, and participated to the “Synchronization of Multi-user Event Media” (SEM) task, confirming in practice the project’s commitment to the evaluation of multimedia analysis and organization technologies through open benchmarking initiatives.

LinkedTV does #icip2014 tutorial on Video Hyperlinking, papers on video analysis and concept detection for cross modal multimedia search

LinkedTV is being well represented at the International Conference on Image Processing held in Paris this year (27-30th Oct 2014). ICIP is the premier conference on Image Processing attracting this year over 1500 attendees.

LinkedTV presented its tutorial on Video Hyperlinking on the opening day of the conference. The 3 hour tutorial was well attended and generated many interesting discussions. It covered the topics of Video Analysis and HyperLink generation, building on the work carried out in LinkedTV’s workpackages on those topics led by partners CERTH and EURECOM as well as on results obtained through the participation to various international benchmarking activities (MediaEval 2014 report coming soon).

Two LinkedTV research papers on “LINKING TEXT AND VISUAL CONCEPTS SEMANTICALLY FOR CROSS MODAL MULTIMEDIA SEARCH” and “NO-REFERENCE BLUR ASSESSMENT IN NATURAL IMAGES USING FOURIER TRANSFORM AND SPATIAL PYRAMIDS” were also presented during the main conference.

LinkedTV brings hypernym discovery to German #DBPedia! @DBpedia_De #lod #lhd #thd #ner

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.

#HyperTED a LinkedTV prototype in the top 10 finalists for the #VICI challenge of @linkedupproject at @iswc2014

“HyperTED: Exploring TED talks at the fragment level” offers a unique and innovative way for exploring over 1681 TED talks at the media fragment level, opening a window to a more effective and efficient dissemination of the knowledge present in those inspirational conferences. Anyone can play with this app at http://linkedtv.eurecom.fr/mediafragmentplayer.

HyperTED has been developed using key LinkedTV technologies such as video chaptering, hot spots detection based on the NERD framework for extracting and disambiguating named entities, and hyperlinking technologies that enable to recommend fragments of other TED talks as well as educational resources such as MOOCs based on what you’re viewing!

Vote for us at http://linkedup-project.eu/vici-peoples-choice/. We are competing for the People’s Choice Vote.

LinkedNews: Web and #HbbTV application for enriched news viewing developed with @rbb_inno. Video demo now available!

The LinkedNews scenario, driven by LinkedTV partner Rundfunk Berlin Brandenburg (RBB), has been released for the project’s third year with two updated approaches to viewer access and interaction with LinkedTV annotations and enrichments:


(1) A mobile application: starting with a connected device such as a laptop and tablet, the viewer can choose a news programme and begin to watch as well as browse the annotations and enrichments on the same screen. They also have the option to send the news programme video to an available other screen (e.g. their TV set) and continue to browse the LinkedTV enrichment content on their mobile device synchronized to the news programme. This is an adaptation of last years’ LinkedNews tablet interface for use with RBB content and enrichments. In particular, the available navigation for browsing enrichments has been aligned to the dimensions of enrichment supported for the RBB scenario which are related news items from RBB and related news items from other sources;


(2) An HbbTV application: starting with a SmartTV or set top box (STB) with HbbTV functionality, the “red button” mode allows the viewer to access the LinkedTV application and begin to explore video chapters and their annotations. For annotated concepts, also relevant information for each concept can be displayed on the main screen. Again, if the viewer wishes to explore further the LinkedTV enrichments they may connect a second screen to the LinkedTV application which will mirror the list of video chapters and their annotations but offer a more complete browsing of available enrichment links from the LinkedTV system using the LinkedNews interface described above.

See the HbbTV application in our video below, made during the IFA 2014 in Berlin this month:
