Image Recognition Problem Finally Solved: Let's Pay People To Tag Photos
Michael Arrington
Mar 29, 2008

Most people have thousands of digital photos sitting on their hard drive. And the vast majority of those photos aren’t tagged or searchable. Want to find the 300 pictures of your youngest son amongst 10,000 others? It’s not going to happen. Unless you’ve been diligently tagging and categorizing those photos over the years, and who does that?

The problem is obvious. The solution, not so much. A trail of failed startups have tried to tackle the problem with a fairly serious application of technology, including: Riya (now focused on ecommerce via Like.com), Ookles (never launched), and Polar Rose (in private beta for nearly a year), among others.

And now suddenly TagCow appears, which allows users to upload photos and have them tagged within a few minutes. The technology appears to be “magic,” meaning there’s no explanation of it.

If there’s a mountain in the photo, it’s tagged. A dog? yep. A yellow cup? Absolutely. It does people, too. Upload an image of a person and say who it is, and all other images you upload will be tagged with that person, too. The service also integrates with Flickr and will auto tag the photos you have on the service.

Thomas Hawk, the CEO of photo site Zooomr, tried the service and declared it “really, really cool,” although he wonders how it works.

The answer is, humans do it. I note that the TagCow site is careful not to say anything about the tagging process, and never use the word “automated” or anything else that would suggests computers are doing the work. Munjal Shah, the founder of Riya/Like, agreed, noting that it recognized a witch in Thomas’ photo – he says this just isn’t something a computer can do today.

I haven’t confirmed this yet. I’ve emailed the company for a description of how the service works but have yet to hear back. Until we do, I’m betting that humans are the taggers. Note that Google has effectively thrown in the towel and uses humans for this kind of work, too.

TagCow appears to be offering the service for free, so the cost side of the business may be a problem for them down the road. And the business is definitely a little sketchy. Worried about the privacy of your data? Just don’t click on their Privacy Policy or Terms of Use: “Privacy policy is TBD.” and “Legal stuff TBD.” Not exactly a way to build confidence.

  • Blowski

    Besides the obvious interest, who cares whether it’s automated or done by humans? If it is done by people, then it’s basically the mechanical turk, a business model that has had a modicum of success elsewhere.

    For the average snapper, tagging is something you have to do yourself. If you get somebody/something else to tag your photos how will it know when/where/why a photo was taken, or who is in the photo? It might recognise famous faces and places, but what about a generic flower, or my baby nephew?

    Professional photographers might pay since more tags leads to more leads. I have no idea whether photographers currently do this themselves for sites like iStockPhoto, but if not, there is a potential business model in there.

  • http://ideeinc.com Leila Boujnane

    Michael: I work in the image recognition and processing field (have been for a decade) and your answer is correct: the tagging is definitely not an automated process; it is manual. Total BS given the tag line “automatically tag thousands of photos”; perhaps “automatically” to them means “tagged by somebody else while you are not looking”.

  • http://www.crunchnotes.com Michael Arrington

    Blowski – it’s only an important distinction if you see a difference between, say, a secretary taking dictation v. a word processor on a computer.

  • http://michaelkimsal.com/blog Michael Kimsal

    what I don’t get is how they can tell who ‘dad’ or ‘emma’ are in the pictures I’d upload for tagging. For generic stuff (car, mountain, people, sunset, etc) this seems pretty straightforward, and yeah, they’re likely using mechanical turk or something like it.

  • Susan Beebe

    The *automagical* tagging technology ‘behind’ the http://www.Tagcow.com site is definitely not clear. Ok, so you think “humans do it.” Now, I am picturing this… there’s like this room of terribly sweaty, overworked ‘interns’ cranking out tags to match photos?! are you serious?

    If that’s the case, then wow, that’s definitely a ridiculous business plan; not viable.

    Don’t even get me started on the privacy policy “TBD” bit.

  • http://chris24.ca Chris Thomson

    “tagged by somebody else while you are not looking” -#9

    That’s probably exactly why they don’t have a privacy policy up yet.

  • Blowski

    @Michael: I would have compared it to a secretary taking dictation and voice-recognition software. You go with whichever gives you the best letter.

    This is interesting. The complexities of solving this problem from a technical standpoint are computationally difficult to say the least.

    I think the better question here is, “Who Cares”? If its done by a human, its going to be more accurate….

    So if it works, and they’ll tag your photos for free, and it’s accurate — who cares?

    Why can’t it be a combination?
    80% automatic 20% human validation. The better it gets the more automatic it gets. Unlike riya it’s a progresive approach that learns from training.

    Its not the business model that is the problem. Its viable as they can get it done at low cost destinations and the work can be done with little or no educational qualifications. Its the privacy issues that come to the fore.

    Sounds like a good idea in theory, but other than the obvious question marks around revenue model, operation, and everything else, there’s one more teensy weensy issue. How many people tag their photos by ‘mountain’, ‘yellow’ cup, ie. random description? I rarely tag my photos due to sheer laziness, but am I the only crazy person who does it by name of the people in the picture, event, date, location, ie. relevant details? How can any system, automated or monkey-operated do that?

  • http://binaryday.com/ Binaryday

    It is practically impossible to get the tagging done by humans. I mean how many people can they employ? Hence my sense is it must be a combination of technology and human tagging. I mean the technology can tag 80% of the images and the humans can correct the rest 20%.

    I believe that is a good way strategy to enter this market. Enter the market, create a presence, then keep investing in the technology to a point where it becomes 95% or so correct. I think the human intervention shall be required for quite sometime to come.

    End of the day, as an end user I do not care how they do it. I just want to get my images tagged properly.

    In corner A: letting TagCow hire random people to tag my *public* Flickr photos.

    In corner B: AOL, MSN, and Yahoo hand over their logs to the U.S. federal government when requested, and not even as part of a criminal investigation, and without telling their users.

    And I’m supposed to be concerned about TagCow? WTF?

  • annonymous

    #36, u have a point. i guess most ppl willnot be worried abt privacy. just look at how they put everything public in flickr,social n/w etc atleast they have some market.

  • http://blogallalong.com Bashar

    We’ve seen loads of ridiculous ideas turn into serious business on the WWW, but I would not bet on this one. Google Image Labeler is using human labeling based on Luis Von Ahn research and project, which is based on making use of people fun time. Paying for labeling is a nasty costly business you can’t afford it. All the time and money it takes to keep up with people uploading their some junk photos.

  • GeMe

    This human-tagging process reminds me of Yahoo whose directory of URL is maintained manually by human. User suggests interesting links to Yahoo which they then add it to portfolio.

    However, human-tagging may not be efficient if the system gain critical mass. It will have to hire more human to tag the content, and that some content may just be missed due to human’s oversight. Moreover, it might be scalable.

    Also what are the privacy implications of this type of service?

    At least in my case I wasn’t really worried about their privacy policy. 100% of my Flickr photos are already public photos. Anyone and everyone in the whole world already has access to these photos by my choice to make them public images. Certainly someone with *private* photos might not want to turn them over to tagcow unless they felt comfortable with their privacy policy.

    Personally I was pretty impressed with the job that they did tagging my photos. They added thousands of highly descriptive tags. This means that more of my photos will likely show up in image searches both on Flickr as well as on Yahoo by extension as the photos are indexed for theses new tags.

    Personally I think that tagcow uses a combination of AI and human resources. I noticed what felt like text recognition on a lot of my photos that had text in them. But they also tagged many of my photos using highly complex conceptual tags that I don’t believe a machine could come up with.

    I believe that there possibly could be clustering of sorts going on as well but am not sure on this. For instance. If a photo is tagged witch, might you not automatically tag a photo with this tag also with “wicked.” Similarly, if a photo was tagged sunrise, might you also autotag the photo morning, etc.

    Certainly human tagging might not be economically feasible. Certainly it might not also scale. But, at least for the time being, it was pretty cool to have someone/somehow spend hours and hours making my photos on Flickr more descriptive at no cost to me. And whatever the case, one of the cooler things I’ve ever seen done on a personal level with the Flickr API.

    A good way to keep your photos organized (aside from human tagging) is with 2pad, an email based photo sharing application. Users send their photos and/or videos to 2pad@pad.com and store their media in their own private online galleries.

    Since 2pad stores the content of their emails with their photos. Users are able to search with keywords to find their media.

    It is done through amazon mechanical turk.

    Workers get 5 photos and are paid $.04 to label all the text in the photo and to “Describe, using simple, generic terms, what you see in the image. (Examples: family, beach, drawing, child, child eating spaghetti, letter, disneyland, envelope, greeting card, etc.)”

    Tagcow’s response to the increased load has been an offer of a $10 bonus to every 200 hits completed (that’s 1000 photos as each hit has 5 photos).

    Be aware since anyone can sign up to mechanical turk, all your photos you want tagged are viewable by the public.

    “I was a guinea pig for TagCow We figured if this was going to do what it says it’d do, that save us a lot of time tagging our pictures.
    In order to use TagCow, you have to register with their site, and upload the pictures to them. You can sign up for their flickr service, which I did, and they are supposed to tag your photo and then upload it to flickr. In order to tag people, you have to upload a picture of that person and assign their name to that picture. I uploaded a picture of me and Clint. Then I uploaded one picture. Several days later, the picture still wasn’t tagged.

    One day after I signed up and uploaded my one test picture, it was confirmed that it is actual humans tagging the pictures. I reported to Clint that my picture still wasn’t tagged. A week later, it still wasn’t tagged.

    Guess what.. I forgot about it.

    Until today. After realizing what the mystery was (”Hey, TagCow finally tagged my picture!”), we realized that it is still not perfect. First of all, why did they change the spaces to underscores in the title? That makes the title stretch all the way across the screen, and I have to actually use the horizontal scroll-bar! Secondly, it tagged Clint in the picture, but Clint isn’t in that picture. Maybe the human thinks Justin looks like the picture of Clint I uploaded? Who knows.

    Anyway, I will not be using TagCow in the future. It’s a neat idea, but in practice, they have a long way to go.”
