I was researching about folksonomy lately and I thought to collect the thoughts in a concise form I’d write something here.
So what is folksonomy? Literally, it’s a combination between “folk” and “taxonomy”. “Folk” references to the lay, casual people (it is plural). “Taxonomy” refers to a system or convention to classify information. So together, they mean system or convention to classify information that is done by lay people. It’s a term coined by Thomas Vander Wal. Ofcourse that is a rough definition of it. But to my own words, instead of using a professionally or predetermined convention of classification system, we let the masses to classify the streams of information. Sounds difficult? Think tagging on Flickr and Delicious, or Wordpress. Instead of having a systematic hierarchy where users could not influence, tagging allows free flows of characters, words or vocabulary to label an information, thus making it possible for one information to have more than one way to classify it.
One easy comparation is how Yahoo! has always organised information in traditional, systemised, predefined hierarchy. Remember the good old Yahoo! homepage where you had the option to seek for information by the search box or by browsing one of the major categories and narrow down? Compare that to the way Delicious or Flickr organise their own information. Delicious and Flickr do not ask you to follow a fixed trail down the road to find an information. It is still a trail, but is more serendipitous. Surely a different way of finding information than if we were in a public library where we hunt down to the exact fixed place. Information is not stored in a fixed place in folksonomy.

Delicious and Flickr have always been hallmark examples of folksonomy. However, they were not the first. A desktop software from Lotus has apparently used it back in the nineties. A software called Bitzi helped classify digital documents on the Web. In the offline world, we also sometimes tag/label things in our homes randomly. “Clothes” can be tagged “pants” and “shirts” too.
What are the benefits and drawbacks of folksonomy versus taxonomy? Here is a summary:
Benefits
- democracy/freedom to put relevance, primarily personal relevance
- allows for serendipity in information-seeking, providing more possibilities
- bottom-up classification allows for more details
- financially inexpensive to deploy
- cognitively also inexpensive, does not need rocket science
- useful where types and scale of information are grand and random, information organises themselves
- individual and community benefit
Drawbacks
- ambiguity: synonyms, homonyms, plysemies, depth of classification
- can pose threat to efforts in creating a semantic web
- can be very detailed and specific, but is very noisy
- can take a long time to have an established labelling
- possibly hamper search speed in circumstances where speed is important
So that’s all I have for now folks. It’s been a productive read today. I have not implemented tagging myself for this blog, I should start somewhere soon. ;)
