Anatomy of a Large-Scale Social Search Engine

Aardvark Q&A engine going to WWW10
  • Users can ask questions in natural language, not keywords
  • Content is generated “on-demand”, tapping the huge amount of information in peoples’ heads
  • The system is fueled by the goodwill of its users
  • 87.7% of questions sent to Aardvark got answered (very high answer rate!)
  • 75.0% of users who asked Aardvark a question also answered a question for someone else (very high participation rate!)
  • 70.4% of answer feedback had a rating of ‘good’ as opposed to ‘ok’ or ‘bad’ (high quality!)
