The HydroTagger is a system for mapping variables in academic investigator databases to concepts. This concept mapping allows us to search for a given concept, such as Nitrogen, and find related variables in various databases no matter what those variables are called in those databases. HydroSeek is an example application that uses this concept mapping.

The HydroTagger is located at http://www.hydrotagger.org/.

Each week, a sniffer goes around to registered ODM web services and identifies variables which haven't been tagged (i.e., haven't been mapped to a concept). If you have a registered ODM database, you can see if any variables are waiting to be tagged from your database. If so, you can tag them through the following procedure.

Note: HydroTagger works best with Internet Explorer.

To use the HydroTagger:
  1. In Internet Explorer, navigate to http://www.hydrotagger.org/.
  2. In the "Private" section, click Tagging Application.
  3. You'll see a list of variables that need to be tagged on the left. Choose one by clicking Select. The variable will appear in the Variable text box.
  4. Using the concept tree, browse until you find the concept that matches your variable. This concept MUST be a leaf node (i.e., a node with no children) in the tree.
  5. Double click the leaf node to add it to the Mapping text box.
  6. Click Map, and you should see the variable mapped on the right.
  7. Repeat until you have mapped all of your variables.

History

HydroTagger was developed by Bora Beran as part of his PhD dissertation.
