We now have our four essays available in RapidMiner. Reading the papers is not enough
however. Gillian's goal is to analyze the papers. For this, we will use a Process
Documents operator. It is located just above the Read Document operator in the Text
Processing menu tree. Drag this operator into your process and drop it into the Paper 5
stream. There will be an empty
doc
port on the bottom left hand side of the Process
Documents operator. Disconnect your Paper 14's
out
port from its
res
port and connect it
to the open
doc
port instead. Remember that you can rearrange port connections by
clicking on the first, then clicking on the second. You will get a warning message asking
you to confirm the disconnect/reconnect action each time you do this. Repeat this process
until all four documents are feeding into the Process Documents operator, as is the case in
Figure 12-8.

Next, double click on the Process Documents operator. This will take us into a sub-
process window.
