Search Web 2.0

According to the French search website, YouVox: SearchTheWeb2 searches are "based on our collective intelligence ... exploits the interrogations of the Net surfers to accelerate a search: when a search is made, one finds on the screen the Google results plus a list of relevant search queries. The list was generated by other Net surfers and dynamically extracted from Google database. The intend of this list, according to the originators of this product, is to improve the performances of search (with the difference with other engines, they are not satisfied only to supply us the most popular, but also give us the rarest). If one takes again the example of Barney Pell, one finds well in the list of the proposals: "books on children" and "books for children" with a classification different from the answers."

The company itself explains that "The queries that people use daily to search online are called as people search language. Vocabulary use in people search language is simple and governed by power law with Zipf distributions. If a query is of two or three word long, it produces a series of relevant keywords with a head and a "the long tail". The head contains several popular terms while the long tail consists of many obscure keywords or longer phrases." [resource]
