The GiveALink.org project invites you to participate in two online
user studies related to tag recommendation and tag-based ranking.
Below are details of each study. We would greatly appreciate it if you
would participate in both studies, or in either one of them. Each
study will take around 20 minutes of your time --- but you can help a
lot even in a few minutes.

Recommending Tags in Social Tagging Systems (IRB study #0910000746)

We invite volunteers to participate in a research study testing
techniques for selecting recommended tags in social
bookmarking systems. Participants will be asked to assess the
relevance and usefulness of tags suggested for urls in the
GiveALink.org system.

To participate, users need to have an account with GiveALink.org.
If you do not have an account you will need to first create one, and then
import bookmarks to the new account from your browser or an existing

study, the data collected is anonymized.
