Are you going to have the taggers pick from a controlled vocabulary or simply make up their own tags? It would be interesting to do both, and perhaps try two different vocabularies: one which has been created socially via something like del.icio.us, and one that might not offer as many alternatives, like dmoz.org. It would be interesting to see if virtual peer pressure is a factor. I also agree that the searchers should not be the taggers if you want a good experimentation.

That could definitely skew. My other comment is that I'd like to see the hierarchical system be a professionally prepared system (so terms are orthogonal, scope notes to describe where things go...) -- otherwise, it's pretty much the same thing as tagging, right? Find classification system for pictures and have your subjects classify pictures according to that scheme...

Some thoughts were that tagging involves more engagement with the material
(higher levels of processing) than sorting in folders. Additionally, the
act of creating a tag may lead to a more durable memory trace (generation
effect). And probably the weakest support for tagging is that it mirrors
the semantica organization or LTM. This is your area, do these reasons

“Is the task of tagging something that creates more of an episodic
memory and the category task more semantic. How do both systems
contribute to the process. How does procedural memory contribute to
the process(experts/automated)”

What a great question…i hadn’t thought about the episodic/semantic
distinction.

Two potential IV manipulations are a sorting task (bookmarks into categories) and tags. What will the directions be like? What are the classic sorting directions? What will be the tagging directions? (Flickr directions / del.icio.us directions / directions controlled or matched to the sorting directions) We are all obviously thinking that tagging will lead to better recall/faster retrieval time/fewer errors, but why? I think I know. Ask your student? What additional directions could be added to the sorting task to make it a tagging task? Don't forget to measure and see if any participants are expert taggers. This could easily be a paper and pencil task. Are you going to write your own program/environment or use some standard(s)? So is this really a sorting task in the classic sense or are you going to have everyone create folders and sort like they bookmark (no super-ordinate or subordinate folders). Is the task of tagging something that creates more of an episodic memory and the category task more semantic. How do both systems contribute to the process. How does procedural memory contribute to the process(experts/automated) Feel free to contact me or have your student contact me to bounce ideas around.
