Locals and Tourists heat map for Flick’r uploads http://bit.ly/9ipzzn
As well as being just darn cool and showing off what we can do when we have large amounts of data and the ability to analyze it, I really like this use of Inferred Metadata. Inferred Metadata is not explicit. In this case the inference is that people who upload photos about the target city during a limited period (a month) are tourists, particularly if they usually upload to Flick’r from another city.
There’s a lot that can be done with Inferred Metadata. Check out my article The Mundane and Magic Future of Metadata in Supermeet Magazine number 4 (it’s free).
