We have been playing with our new image search service and doing all kinds of interesting searches. The questions in my mind is: when you do a Google image search, you typically find images that are tagged with your subject matter tag: say I am looking for “Uncle Sam” images, I find images that are tagged “Uncle Sam” or in a page with “Uncle Sam” text in close proximity to the image. Now how different would my image search results be if I used an image as the input. No tags, just an image of “Uncle Sam” and ask an image search engine to retrieve all of “Uncle Sam” images. How different would the results be?
I am betting they will be quite different. So we are continuing to play with our image search engine!
