My first 2 talks available online: Tags & 21st Century Democracy

The two talks I gave at the: International Workshop on Challenges and Visions in the Social Sciences, this summer, are now available at videolectures.net.
Not the best talks of my career, and hopefully not the last either. But the guys at VL did a great job in recording them.

One of the talk was about Tags, and the second about Democracy of the 21st Century.

In the one about Continue reading My first 2 talks available online: Tags & 21st Century Democracy

The new project: TagBay. Tagging e-Bay

It is now the time to present the next project we have been working to: TagBay. And I say ‘we’, because is this project I am not alone. I did it with a friend of mine, Derek, who accepted, very patiently to code, some of the idea I have been tinkering around in the last year or so. I am speaking about how tags, and tag clouds, and distance between tags, and so on.
So, in brief we made a web site to tag material that is being sold on e-Bay. Anybody can tag any object that is being sold. Not only can any object be tagged but you can tag sellers, too (oh, we are not responsible for offensive tags, eh!).
Tags on objects can be made private or public, and you can also search among your tags, among everybody else tags, and eventually (when we code it) it will be possible to search among the tags of another user, like in del.icio.us.

Now that the summary for the people who have no time has been done, let’s try to explain the idea in the details for those who have a bit more time.

Tag Bay: Tagging e-Bay

Pages:
On TagBay, right now, there are 3 type of pages: e-Bay Search Pages, TagBay Tag Search Page, TagBayUser Tag Search Page, Item Page, and Seller Page.

  • Search Page: It is possible from inside Tag Bay to make searches on e-Bay on specific keywords. The user can then add tags to each object that came out, store the tags added all at once, or store the tags of a single object. The same thing can be done in the Tag Search Page
  • TagBay Tag Search Page: In this page the user gets all the results for a single tag that someone have used. Nothing fancy (for now). Items where the tag only appears as a private tag will not appear here.
  • TagBayUser Tag Search Page: In this page the user gets all the results for a single tag that he have used. If the user is logged in and is looking at his own tags, also the items tagged in a private way will appear.
  • Item Page: Each object has its specific page. From such page any user can see what are the public tags that other users have used for that page. Also they can define their personal tags for that object, if their tags are going to be private, and the tags of the seller.
  • Seller Page: And then there is the seller page, and in the seller page any user can tag any seller. The use of tag for sellers is still limited, but will be increased in the future.

The natural use of the site

  • For a seller or for a shop A seller might want to use the site to tag all the objects that he is selling, giving for each object all the tags related. Thus increasing the possibility for it to be found. We suggest to list the tag in the order of importance, as soon we are going to use the order consider the importance in the search page.
    Also, if a person wants to make a cool list of objects, they can tag exactly those objects, with a tag they never used, and then link to the page in their directory of this tag. Thus creating on the spot, their lists. Also sellers will want to tag their objects, and people making searches will tag objects to make lists of objects they want to follow, before jumping on a transaction. We think there is more than enough material to generate interesting behaviour. It doesn’t have to be exactly the same emergent behaviour that we are used to see. After all we are just exploring the possibilities of social folksonomy.
  • A shop To the possibilities before, a shop who is selling on ebay might be interested to make sure that the shop itself (remember that you can tag sellers, and not only shops) have all the tags related to the merchandise that they are selling
  • Someone buying Our suggestion for someone who wishes to buy, on e-Bay, would be to first look under the tag search, to see if there is anybody who has already tagged any object that they are interested in. This does not necessarily be someone else who is buying, but also someone who is selling. Then tag the objects they are interested themselves, to have it in their own list of objects. Then they could go to the search e-Bay page with the necessary keywords, and add the chosen tag to all the objects interesting. At that point a first selection have been made, and all the possible objects have been tagged. At this point, he could choose one or those objects, change the tags to private, and start betting on it.
  • Someone suggesting And finally if someone is just trying to suggest some possible objects, he could search e-Bay for those objects, tag them with a unique tag and present the url of the list to whoever is interested.

There are many other ways to use TagBay. In a sense TagBay is a toy, and not a game. And as every good toy it can be used for many different games. We suggest here only some of them. Also TagBay itself is rapidly evolving. We have tons of stuff we are interested in including, and if you have been reading my blog, you know how my problem is always to find people to code my ideas, more than to find them. And this is why I am so happy for Derek work!

Difficulties that we found:
There were a number of issues that came out when we started developing this program.

  1. Public vs private tags:
    Why would someone tag an object if they are interested to buy it? After all aren’t they making it easier to others to find it, by adding those tags?
    This was a serious doubt that we had, and finally we decided to give the possibility to users to tag objects privately. Yet there have to be a balance between private tags and public tags, as public tags are necessary to generate the emerging folksonomy that we wish to use. So we decided for a compromise: public tags can be done from the search page, but private tags requite you to go to the specific object page. In our view (but we are ready to be proven wrong) someone would go to the search page, tag all the entries where he might be interested. Then chose one, and tag that one in a private way.
  2. Limitations due to the temporary nature of the objects
    Considering that most object exist on ebay only for few weeks before being sold, wouldn’t this be not enough time to make a tag cloud and let all cool emergent properties that folksonomy induces, appear?
    Maybe, but sellers also can tag the objects they are selling, thus giving a fresh start to all the objects. Also side by side to tagging object we are giving the possibility to tag sellers. Which eventually should survive each transaction and build up an interesting tag cloud.
  3. I spoke about sellers tagging their own objects, but wouldn’t this invite people to spam your site? After all, wouldn’t it be much better for a seller to add many tags to be present in many searches?
    Ah ha! You think tag clouds can be spammed. This is false. Tag clouds cannot be spammed, and no one understand this. And we shall use this site to prove it. We have nothing against spammers, they are absolutely welcome in our site and spam it as much as they feel. Add all the tags they want to each object they sell. It will make ABSOLUTELY NO DIFFERENCE in the search page. Tag clouds are unspammable. And our engine will use tag clouds as its base. Everybody else uses tag sets. And this makes them easily spammable. So, no we don’t fear spammers. In fact we hope that spammers will come to our TagBay site. They are just people trying to sell their stuff, we are trying to make sellers meet with buyers. Wouldn’t be bad to single out spammers just because they are spammers.

TagBay is obviously still in beta, and there are many things that need to be coded. If you have any idea on how to make it better please do not hesitate to contact me. If you want to make a difference on what the final product will be now is the time to do it. Also all new suggestion implemented should be listed in a special page with links to the original suggester home page.

Review: Smarking

Some of you might remember my rant, once del.icio.us was bought. And some others, who where with me from before might remember the entries I wrote on tag clouds. Some time later I was contacted from an Italian developer, Fabio Vescarelli, who asked me some help in developing some algorithms to find the distance between users in a del.icio.us like program. We had an exchange of email first , and we met in chat some other time. He was building a del.icio.us clone, Smarking. But with some interesting differences. Continue reading Review: Smarking

Tag Clouds are hard to Spam

I think the time have come to write my third, and hopefully last contribution to the topic of tagclouds.

I have been hearing a lot of talk on how users should not use too many tags in linking to url. I also am the maintainer of the mindmap maker, and I often look at some of the maps generated (available to everybody). There is a number of people who tend to use an average of between one and two tags per URL. Their maps are often very ordered. No clustering, no hierarchy. (Forgive me if I don’t put a link to such a map, but since I am going to bash this way of using delicious, I’d rather bash a method than a specific human being. Just go to the list of maps and open a couple, odds are one of them will be of the type I am describing). This way of using delicious uses tags as folders, just with the modification that every now and then you can put an URL in more than one folder at the same time. A bit like big bookstore might carry several copies of the same book, and store them in more than one place (and the Tao Te Ching, ends up in New Age -God knows why- and in Religion).

Of course tags tend not to fit exactly. My Tag Clouds and Cultural Change will be under Tags or Folksonomy or Sociology… Whatever you chose you probably will not put it under Ajax. And yet most of the analysis was done studying the spreading of the term Ajax.

Let’s make a few simple calculations. Continue reading Tag Clouds are hard to Spam
