A Teacher’s Tour Guide into the New Read/Write Web2.0 - 10 Part Series
OBJECTIVE: Define folksonomy and get you started with tagging
Schools need to stop teaching the Dewey Decimal System and start empowering our students with folksonomy. After RSS and subscribing, folksonomy and tagging is the next essential philosophy and skill one must adopt in order to adapt and survive in “New Read/Write Web2.0″. The folksonomy revolution is pushing this current “Social Web2.0″ into the “Semantic Web3.0.” This new classifying phenomenon has reformed the way users organize, share, search, and label their digital pictures ( flickr), bookmarks (delicious), and videos (youtube) collections.
WHAT
Folksonomy, folk + taxonomy, is a new way to organize and label information using tags. Tags are keywords that give meta data, data about the data, which enable classification. Furthermore, folksonomies are social and collaborative because they use “cooperative classification and communication” that builds a collective intelligence for users to contribute and tap into. A better way to define folksonomy is to explain what is not.
*Non-binary: With folksonomy, you can apply multiple tags to data rather than choosing just one category to file under.
*Non-hierarchical: Instead of top down folders and sub folders, tags are organized in tag clouds where the more popular a tag the bigger the size. The following picture is an example tag cloud surrounding the concept of Web2.0.

WHY
Four reasons why you need to start tagging:
1. Tagging is easier than categorizing. Rashmi Sinha’s post “A Cognitive Analysis of Tagging provides two brilliant diagrams that represent the frustration behind the paralysis by analysis effect when we tried to find the “right” or “best” category to file. Then she illustrates the tagging process which shows you how it cuts off the last step making it easier and more enjoyable to label.


2. Tagging makes it easier to remember and find. Since you can apply multiple tags, you can sort, search, and file under multiple contexts.
3. Folksonomy allows you to tap into the wisdom of the crowds and jump on the long tail of the collective intelligence and emerging trends. Exploring and browsing through tag clouds allows you to discover trends and interests that you may otherwise never have been able to think of to type in google or stumble on.
4. Folksonomy is social and leads to sharing. You have the ability to find like-minded individuals and tap their brains, tastes, interests, and favorite sites.
HOW
Although their is no set standard and controlled vocabulary here are some general guidelines to get you tag clouds started on the right foot.
1) Use keywords.
2) Use multiple tags.
3) If you are going to use multiple words with in one tag use an underscore. Example “professional_development”
4) Be conscious of nouns and verbs when tagging. If I find links that are resources about how to blog, I will tag it them under “blogging.” If I find some interesting blogs I tag them with “blogs.”
DISCUSSION:
1) Do you think we as educators should take a role in setting up standards for some sort of common lingo with tags?
2) What tags do you use to organize and label your educational digital links and videos?
