Writing for El Universo, one of the largest daily newspapers in Ecuador, Francis Pisani, the highly-respected independent journalist who authors a technology blog for Le Monde, reviewed a number of search technologies in a column entitled “Improving Your Search” and had this to say (translated from Spanish):
The most useful is Surf Canyon, which offers a “real-time personalized search” that uses an artificial intelligence formula to adapt to the specific demands of the user. The idea is simple: only a small percentage of responses offered by any search engine correspond to what really interests us. Surf Canyon interprets each click as an indication of what may concern them and then finds similar information in the results offered by Google on the following pages (2, 5, 10, etc.) which are then deployed immediately below the newly activated link. The selection improves with every click, saving the user time.
