As the best thinkers are discussing the future of AI at the
Singularity Summit, perhaps we shouldn't just be looking at ways to create better computer artificial intelligence, but at ways to more efficiently make use of human intelligence that's available all the time. For example, take a look at the technologies being used to harness human cognitive abilities
to help in the
search for Steve Fossett's plane in the vast desert of
Nevada. Searchers are leveraging Amazon's Mechanical Turk community to
quickly scan through Google Earth satellite imagery to flag areas
where the plane might have crashed or eliminate barren areas where
rescue pilots shouldn't focus on. At the time of this post, there are
still
over 100,000 blocks to be looked over with each block representing a 278x278 sq ft. area. At what appears to be a
scanning rate of about 10-20 square grids/sec by the Turk community, the entire area of interest
could theoretically be searched in less than 5 hours -- assuming that the system isn't showing the same photo to multiple people (as appears to be the case). Contrast that to the
(super)computing resources required to process an equivalent image of
more than 8 billion pixels (img dimension(256x256) x (numOfImgs)100k),
on top of the difficult task of defining the object-of-interest to a
computer (what does a plane wreck look like to a computer?).
In this instance, using simple coordination mechanisms, human
intelligence becomes an economic way to solve a hard problem -- which is exactly the
rationale behind Amazon's Mechanical Turk. We have
seen projects using other hooks and mechanisms to leverage human
intelligence, like
Recaptcha for OCRing books, and
the ESP game for
tagging images -- and even the
Techdirt Insight Community, which is bringing you this post. On a grander scale, Amazon's Mechanical Turk is trying to be a platform for "artificial artificial intelligence", though so far the success stories for MTurk have been minor. Even in this case, it's not entirely clear how useful it is (or how they got the latest satellite imagery ready to go for this task). In fact, while there are fairly stunning reports that, in searching for Fossett, the remains of
eight other plane crashes have been discovered -- it doesn't sound like any of them were found via Mechanical Turk and Google Earth. Still, with all this talk about mashing up web services and better artificial intelligence, perhaps it's time we start thinking about more effective and efficient ways of leveraging human intelligence?
