In Tutorial 2, you used a
command-line tool to build a model. In this step, we'll use the UI to
process documents using, among other things, the
model you built. We're going to use the same simple named entity task
with MAT, and we're going to assume that your task is installed.
Like Tutorial 2, we're going to do this
tutorial in file mode.
In this tutorial, we're going to make use of the models we build in
See the documentation on starting the Web
server and starting the UI. If you
failed to shut down your Web server at the end of Tutorial 1, shut it
down and restart it now; any models you built in Tutorial 2 won't be
visible to the server until you restart it.
Back in Tutorial 1,
we used the UI to prepare a document for hand tagging. Please repeat
steps 3 and 4 from Tutorial 1, except you should use the "Demo"
workflow instead of the "Hand annotation" workflow. Once you complete
those steps, you should see a window like this:
Note that the zone and tokenize steps are grayed out, indicating
that they've been completed, and that the word units in the document
are delimited by gray boxes.
You may recall from Tutorial 2 that
we built a default model for
the Named Entity task. The UI knows about this default model, and we
can use it now.
Press the forward button again. The "tag" label in the Status line
should blink momentarily while the Web server loads the model, and then
you should see a window like this:
In the UI, you can undo an operation.
Press the backward button. The UI will warn you that it's about to
undo unsaved changes:
Press "Yes", and the document will return to the state it was in at
the end of Step 2. Press the forward button again, and the document
will return to the state it was in at the end of Step 3.
At this point, you can hand-correct annotations in the same way you
added and edited annotations in Tutorial 1.
also save the document.
If you're not planning on doing any other tutorials, and you don't
want the "Named Entity" task hanging around, remove it as shown in the
final step of Tutorial 1.
