  5. (Retired) text document tracks � Ad-hoc text retrieval � Text categorization � Snippet generation � QA and fact extraction � News clustering � Search by sample document 20.09.2012 ROMIP 5

  6. Image collections � Photo collection: 20,000 images from Flickr � Dups collection: 15 hrs video � 37 800 frames � Panoramic series: 55,000 images (data recycled from Internet Math 2011) 20.09.2012 ROMIP 6

  7. Image tracks � Content based image retrieval � Near-duplicate detection � Image annotation � Finding panoramic series 20.09.2012 ROMIP 7

  8. ROMIP by 2011 • Low participation from academia • Fatigue of classical IR tasks available relevance tables – no need to participate • • overfitting on available datasets; • hard to model realistic settings and data; • well-studied tasks – new results are hard to expect. • Limited resources • ML challenges (e.g. www.kaggle.com) 20.09.2012 ROMIP 8

  9. ROMIP light 2011 • Sentiment analysis • Search by query image (low participation � ) • Schedule shifted to fall 20.09.2012 ROMIP 9
