What are the most popular photo subjects in each location of your city? Is there any easy way of finding out? Those are questions UC Berkeley researcher Alexander Dunkel is trying to answer, and he has his sights set on Flickr as a possible solution. By combining the location geotags and context tags attached to many (or most) of the service’s photos, Dunkel is able to create tag cloud-style maps of any location that reveals the tags that dominate each location.
Tag clouds are a neat way of visualizing what content is about, and Tagerator is a simple program that generates them for your Flickr photo tags. Created by Jeremy Brooks (the guy behind SuperSetr), the simple Java app will run on any computer that has Java 1.6 installed. Besides its ability to generate the tag clouds for you, it stores the tag information gleaned from your account to disk, allowing you to use the tag/count information however you’d like.
