The goal of this step is to teach Advanced Designer how to determine the class of a document. We need to upload a document set for training, assign reference classes to the uploaded documents, and train the classification activity.
  1. Download the documents that will be used in the skill and unzip the archive.
  2. Double-click the Classify By Text and Image activity to open the Activity Editor.
  3. Click the Upload button on the toolbar and select Upload Documents…
  4. Select the documents you downloaded earlier and click OK. All these documents will be uploaded to the No Class list.
  5. Now we need to create classes and assign them to uploaded documents. In this tutorial we will use two classes - one called “DE” (for German documents) and one called “BE” (for Belgian and Dutch documents). a. Select all German documents in the list. b. Click Create Class in the toolbar. c. Enter the class name “DE” and click Create and Assign. d. Select the rest of the documents in the No Class list. e. Click Create Class again. f. Enter the class name “BE” and click Create and Assign.
  6. Once classes have been assigned to documents, train your activity using the Train Activity button. After training has finished, statistics regarding the classification results will be displayed on the Results tab. Analyzing these statistics helps identify problem classes and evaluate the overall quality of the classifier. The metrics and methods for fixing classification errors are described here.
Note: There are many ways to upload documents and assign classes. If your documents are organized into subfolders by class, you can select the Upload Folder Like Classes… option in the Upload menu. Advanced Designer will automatically create a class for each subfolder and assign it to all documents uploaded from this subfolder.
  1. Click the name of the skill to exit the Activity Editor and go back to the Activities tab.
