The next generation of search engines should not simply retrieve URLs, but should aim at retrieving information. We designed a system that leads into this next generation, leveraging information from across the Internet to grow an authoritative list on almost any topic. Our method starts from a small seed of examples, and intelligently grows a list of items relevant to the seed.
This method takes advantage of the wisdom of the crowd, in the sense that there are many experts who post lists of things on the Internet. We use a collection of simple machine learning components to find these experts and aggregate their lists to produce a single complete and meaningful list.
Growing a List. Data Mining and Knowledge Discovery.
