On reusing other people’s experiences

The Web is a vibrant environment for innovation in computer science, AI, and social interaction; these innovations come in such great number and speed that it is almost impossible to follow them. This paper will focus on some emerging aspects on the web that are a great opportunity and challenge for AI, specifically the large amount of records of experiences about the world that individual people share in the Web. I discuss a new approach that, instead of focusing on improving information access in the web, aims at supporting people to reuse other people's experiences, recorded in the web, in order to take more informed actions in the world.
