When you set up GATE for the first time to annotate, then
once you have started GATE, use the menu to go to File->Manage CREOLE
plugins. If the mpqa-annotation schema (the exact name may vary) is already present in the list of "Known
CREOLE directories", select it and check the radio button for Load now.
If you want GATE to be set up automatically for future annotation
sessions, too, then select Load always as well. Click the OK button and
the schema is loaded.
At the moment, the correct creole repository to use is:
http://www.cs.pitt.edu//mpqa/opinion-annotations/gate-annotation-new/
If you didn't find an mpqa CREOLE directory in the list, then use the button at the bottom of the popped up window to
"Add a new CREOLE repository" and type in the above address.
If this still doesn't work for you,
there might be a problem with the web-server. If you're a local, you can ask somebody in the
lab for help.
