  1. Slovak University of Technology in Bratislava, Faculty of Informatics and Information Technologies, Institute of Informatics and Software Engineering Human computation JakubŠimko 22.9.2010 jsimko@fiit.stuba.sk

  2. Human computation • Humans can easily solve problems impossible or hard for computers • Our interest • Resource annotation (images, audio…) • Ontology building • General purpose • Virtually anypozriem, vidím problem

  3. But human cycles are precious… • How much do you evaluate your manhour of tagging images (8 h/day)? • At least 10 € netto for me  Dog Food Bench Backyard

  4. …really that precious? • 9 billion human-hours of Solitaire in 2003 • Excluding entertainment, games are complete waste of human cycles

  5. Game with a purpose (GWAP) • Gaming combined with problem solving • Problem definition mapped to game task • Successful game strategies and solutions generated by players are collected as problem solutions

  6. ESP Game (Google Image Labeller) • A game of image tagging • 2 anonymous players • Players need to guess the same word describing the picture Player 1 Player2 Puppy Cute Dog Dog Food Bench Backyard

  7. Verbosity • Game of collecting common facts (smelling an ontology here  ) • Asymetric game for 2 players • Player A is given a word: “milk” • Using predefined sentence templates, player A describes the word: • “It is a liquid” • “It is usually found in the fridge” • Player B has to guess the original word

  8. Manhattan Story Mashup • Multi-player tagged image creation and story mashup event • Online players and urban players distributed in teams • Online team members write stories • Nouns are extracted and sent to the urban players • Urban team members take photos that best fit the nouns • Accuracy of photos is cross-validated by other players • Stories (enriched by photos) compete

  9. Interesting sources • http://video.google.com/videoplay?docid=-8246463980976635143# • Ahn, L.v. and Dabbish, L. Designing games with a purpose.

  10. What can we do? • Play Games with a Purpose (GWAP) instead of normal games • Create a GWAP • Create a methodology for creating GWAPs
