5. Audio-Visual Explosion
• EU alone hosts 500+ online video platforms
• 42.7m hrs of footage in online archives of broadcasters
and producers (61% of archive footage is online)
• UGC on the advance:
– YouTube receives 100 hrs of video/minute
– Vine and Instagram video
• Internet video is now 40 percent of consumer Internet
traffic, and will reach 62 percent by the end of 2015, 75%
in 2017

6. Search
• Efficient and Effective Search techniques for
Textual Information (i.e. Google Page Rank)
• What about Multimedia Documents?
Audio-Visual and Beyond
– Much work on Audio (Fingerprint/ASR)
– Two decades of work on Content-Based Image
Search
– Little work on MMuullttiimedia

9. Hyperlinking in practice
• Linking multimedia documents with related
content
• Automatic Hyperlink Creation
– Different from Search (no user query)
– Query automatically crafted from source document
content
• Outreach
– Recommendation system
– Second screen applications
