CNET reports that computer scientists and a growing collection of start-up companies are finding new ways to mine human intelligence in the goal of adding a layer of meaning on top of the existing structure of the web, which would make it less of a catalogue, and more like a guide. In addition, this research would provide the foundation for systems that can reason in a human fashion, with machines thinking for themselves instead of simply following human commands. This breakthrough has eluded scientists and researchers for more than half a century. Described as “Web 3.0,” the effort is still nascent, and the idea has given ammunition to skeptics who think it is an unrealistic vision. However, the underlying technology is quickly gaining supporters, both from large companies and smaller firms. The projects aimed at creating Web 3.0 all depend on the increasingly powerful computers that can quickly and efficiently surf and examine the web…
