Why you might want to start using ED in addition to your normal tags

The images in the picture are from the first page of results for a Google image search for "hippocampus", which, to the best of my knowledge, relies exclusively on automatically extracted tags from text surrounding the image or from the tags collected by the Google image labeling game. The yellow box in the middle represents the normal tag "hippocampus" and the blue boxes represent the equivalent ED tags.

Things to notice:



  • With ED tags, the three different senses of the word are captured through reference to the appropriate ontology.
  • The context and the meaning of these 'semantic' tags are created through the links between the terms.
  • Using the structure found in the ontologies, the ED tagged images can be found in a number of ways aside from querying by the exact tag. E.g. queries for "Mythical Creatures", "Brain", and "Chordata" can all be answered effectively by the ED system.

    Seems pretty cool doesn't it? Why not give it a try and let me know what you think? Thanks for any thoughts...
