  1. Research 2.0Harnessing Collective Intelligence Yung-Yu Chuang 莊永裕 Communication & Multimedia Laboratory National Taiwan University

  2. Research 2.0 • Research 2.0 = Research based on the concept of Web 2.0 • Similar idea/term was proposed by Harry Shum of MSRA • Observations from vision and multimedia research

  3. Web 2.0 Web2.0的精神在於”肯定網路上不特定多數人並非被動的服務享受者，而是主動的創作者，並積極地開發技術或服務，鼓勵這些人參與。” 梅田望夫

  4. The long tail 80-20 rule Law of the vital few Books, media, software… Web 2.0 involves all people and shifts the authority.

  5. Web 2.0 (Tim O’Reilly) • The web as platform • Data is the next Intel Inside • Harnessing collective intelligence • …

  6. Research 2.0 • Data, paper and code are on the web • Benchmark becomes more and more important. Sharing your data and code is likely to make your research more influential.

  7. Stereo problem

  8. Middlebury stereo page

  9. Middlebury stereo page Performance for over 40 methods were reported; 36 of them were submitted by other researchers.

  10. Middlebury stereo page • A review paper along with a benchmark was published in IJCV 2002. • 541 citations since then according to Google scholar.

  11. LIBSVM (C.J.Lin at NTU) • 873 citations since 2001 according to Google scholar. • SVM is not necessarily the best tool for classification. • Its popularity could gain from some robust and easy-to-use tools.

  12. Research 2.0 • Data, paper and code are on the web • Benchmark becomes more and more important. Sharing your data and code is likely to make your research more influential.

  13. Research 2.0 • Data, paper and code are on the web • Benchmark becomes more and more important. Sharing your data and code is likely to make your research more influential. • Explore vast amount of (noisy) data • Statistical approaches (machine learning, data mining, information retrieval)

  14. Landmark project • What are the text keywords for landmarks? • What are the visual keywords associated with landmarks?

  15. Research 2.0 • Data, paper and code are on the web • Benchmark becomes more and more important. Sharing your data and code is likely to make your research more influential. • Explore vast amount of (noisy) data • Statistical approaches (machine learning, data mining, information retrieval) • Utilize collective intelligence • Good designs and motivations encourage people to make contributions

  16. What can users contributes? • YouTube/flickr: media and tags • Wikipedia: knowledge • Amazon: reviews/comments • Connextions: courses • MIT’s openmid: common sense • Human computation cycles

  17. Application to ROI • We have applied this idea to ROI research. • There is no benchmark • There is no evaluation • There is no example-based approach

  18. What is ROI?

  19. How to detect? • Heuristics • Contrast • Face • Text • Shape …

  20. How to detect? • Heuristics • Contrast • Face • Text • Shape … • User labeling • Manual • Eye tracker …

  21. Our approach • Collect large amount of ground truth • Evaluate existing algorithms • A learning-based algorithm

  22. Conclusions Because of Internet’s paradigm shift, what are new research possibilities? The answers are left to you.
