Hypothesis

• Lexical resources acquisition with games
• Free
• (sometimes people are even willing to pay for

• Fast
• Rather good quality
• (precision and recall)

Game principle

• Properties
• Randomized words
• The other player is not know during the game
• Until its completion and the display of the
  results
• Asynchronous play
• Either creation of a new game or completion of a
  pending game
• Points
• if the relation has a low weight
• - if the relation has a high weight
• Taboo words
• When for t1--Rw-gtt2 if we have w gt threshold
  then t2 is taboo
