While at Yahoo! Research I was involved in various projects on analyzing, extending and utilizing tagging of Flickr photos. We analyzed what type of tags users applied to their photos and devised a method for classifying those tags into semantic categories. We developed two prototypes, one for tag recommendation and and one for tag based browsing of photos. We started our tag analysis by mapping tags to WordNet broad categories and found out that while users annotations are sparse, they…
Fannr – Flickr Annotator – was a prototype application for assisting users in annotating their Flickr photos. Two types of annotation support is provided when annotating a single photo: tag recommendation and location recommendation.

The TagExplorer was prototype that I made while at Yahoo! Research in Barcelona. The TagExplorer enabled browsing Flickr photos using semantically organized tag clouds. The prototype combined two research projects that I was working on at the time, tag recommendation and tag classification (see references below). For example, if the user typed in London, they would be presented with photos from London (obviously), together with semantically categorized refinement suggestions, such as the locations England and Southwark or the landmarks Big…
