CLARIN/CLARIAH Collaboration on Automatic Transcription Chain for Digital Humanities

In the CLARIAH project, we are developing the Media Suite, an application that supports scholarly research using audiovisual media collections. In 2017 we will also be integrating tools that support Oral History research in the Media Suite. From 10 to 12 May 2017,  scholars and technology experts discussed the development of an automatic transcription chain for spoken word collections in the context of CLARIN, the European counterpart of CLARIAH, at a CLARIN-PLUS workshop in Arezzo. We observed that CLARIAH and CLARIN use a different but interesting complementary approach to the development of such a transcription chain that encourages further collaboration.

On developing benchmark evaluations

The Multimedia COMMONS 2016 workshop (October 16 2016) –that will run as part of the ACM Multimedia conference in Amsterdam– will provide a forum for the community of current and potential users of the Multimedia Commons. This is a multi-institution collaboration initiative, that was launched last year to compute features, generate annotations, and develop analysis tools, principally focusing on the Yahoo Flickr Creative Commons 100 Million dataset (YFCC100M), which contains around 99.2 million images and nearly 800,000 videos from Flickr. The workshop aims to share novel research using the YFCC100M dataset, emphasizing approaches that were not possible with smaller or more restricted multimedia collections; ask new questions about the scalability, generalizability, and reproducibility of algorithms and methods; re-examine how we use data challenges and benchmarking tasks to catalyze research advances; and discuss priorities, methods, and plans for continuously expanding annotation efforts.

At the MMCommons workshop I will discuss the development of benchmark evaluations in the context of  a series of tasks focusing on audiovisual search emphasizing its ‘multimodal’ aspects, starting in 2006 with the workshop on ‘Searching Spontaneous Conversational Speech’ that led to tasks in CLEF and MediaEval (“Search and Hyperlinking”), and recently also TRECVid (“Video Hyperlinking”). The value and importance of Benchmark Evaluations is widely acknowledged. Benchmarks play a key role in many research projects. It takes time, a well-balanced team of domain specialists preferably with links to the user community and industry, and a strong involvement of the research community itself to establish a sound evaluation framework that includes (annotated) data sets, well-defined tasks that reflect the needs in the ‘real world’, a proper evaluation methodology, ground-truth, including a strategy for repetitive assessments, and last but not least, funding. Although the benefits of an evaluation framework are typically reviewed from a perspective of ‘research output’ –e.g., a scientific publication demonstrating an advance of a certain methodology– it is important to be aware of the value of the process of creating a benchmark itself: it increases significantly the understanding of the problem we want to address and as a consequence also the impact of the evaluation outcomes.

The focus of my talk will be on the process rather than on the results of these evaluations themselves, and will address cross-benchmark connections, and new benchmark paradigms, specifically the integration of benchmarking in industrial ‘living labs’ or Evaluation-as-a-Service (EaaS) initiatives that are becoming popular in some domains.

Video Hyperlinking Explained in 7 minutes (in Dutch)

On the 2nd of February I was invited to have a short introduction on video hyperlinking at iMMovator‘s Cross Media Café.  Here are the slides and there is also a video:

Topic models and diversity in video hyperlinking

Video Hyperlinking

The use of hierarchical topic models to find anchor-target pairs could potentially improve diversity in video hyperlinking, and the evaluation of video hyperlinking should focus more on assessing serendipity in the links. These are two important findings of the work of Anca-Roxanna Simon who defended successfully her PhD thesis on “Semantic Structuring of Video Collections from Speech: Segmentation and Hyperlinking”, Wednesday 2nd of December at the University of Rennes, France.

Video Hyperlinking @ TRECVid-2015

Video Hyperlinking

After running a video hyperlinking benchmark evaluation for a number of years at MediaEval, we are excited to have now an evaluation running on video hyperlinking at TRECVid as well. On the 17th of November 2015, we discussed the results of the evaluation and the plans for next year at the TRECVid workshop in Gaithersburg, US.

Benchmarking the concept of video hyperlinking already started in 2009 with the Linking Task in VideoCLEF that involved linking video to wikipedia material on the same subject in a different language. In 2012, we started a ‘brave new task’ in MediaEval, where we explored approaches to benchmark the concept of linking videos to other videos using internet video from blip.tv.  In 2013-2014, ‘search and hyperlinking’ ran as a regular MediaEval task, this time with a collection of about 2500 hours of broadcast video from BBC instead of internet video.

Thanks to MediaEval we could improve our understanding of the concept of…

Video Hyperlinking @ ACM Multimedia 2015

Video Hyperlinking

IMG_3739The SLAM Workshop on Speech, Language and Audio in Multimedia, connected to the ACM Multimedia conference and located in Brisbane, Australia this year, had a special session on Video Hyperlinking on Friday the 30th of November 2015. It was a good opportunity to discuss in more detail the results of the MediaEval benchmark evaluation on ‘Searching and Anchoring in Video Archives (SAVA)’ and to look forward to the upcoming 2015 TRECVid benchmark evaluation workshop. Video Hyperlinking became one of the TRECVid tasks this year. More on Video Hyperlinking and TRECVid after the workshop 16-18 November.

IMG_3754At SLAM, there was a session with four presentations on Video Hyperlinking. Benoît Huet (Eurecom) introduced the session with an overview on the topic. The rationale behind video hyperlinking is that it can help to improve access to archived video, a topic that was central to recently finished EU projects AXES and LinkedTV. Benoît provided…

Pop-up archiefvideo

axes-randomvisualHet efficiënter beschikbaar en doorzoekbaar maken van grote videoarchieven is al jaren onderwerp van intensief onderzoek in diverse nationale en internationale projecten.  Het AXES project dat eind maart 2015 werd afgerond, leverde een belangrijke bijdrage aan dit onderzoek door de technologie voor het analyseren en doorzoeken van video’s een forse stap verder vooruit te brengen en tegelijkertijd goed te kijken naar de gebruikerswensen van diverse gebruikersgroepen die geïnteresseerd zijn in videoarchieven. Denk aan producenten en journalisten die videomateriaal willen hergebruiken voor nieuwe producties, onderzoekers die kennis willen opdoen door (grote hoeveelheden) video te analyseren, of ‘de thuisgebruiker’ die uit is op ‘infotainmenten op een toegankelijke en speelse manier informatie wil opdoen of gewoon een leuk filmpje wil kijken. Met name voor deze laatste groep, die niet altijd meer achter een PC zit, maar op de bank, in de tuin of in de trein met een tablet op schoot, heeft AXES nieuwe concepten ontwikkeld om interessante video’s uit het archief naar boven te halen en naar de gebruiker toe te brengen. Hieronder een kort verslag van deze nieuwe concepten.
