Create document sets for Extraction Rules activities > Create separate document sets for the German and Belgian-Dutch Extraction Rules activities so each trains on the right class. Each Extraction Rules activity should train only on documents of its own class for better accuracy. By default, every activity uses **All Documents** — separate the documents into two activity-specific sets so each Extraction Rules activity trains only on the documents that match its class. 1. Open the "Sick Note DE" activity in the **Activity Editor**. 2. Click **All Documents**. 3. Select **Sick Note DE Document Set** from the drop-down list. 4. Repeat the same three actions for the "Sick Note BE-NL" activity. Click the name of the skill and then go to the **Documents** tab. The two document sets named after the Extraction Rules activities appear in the list on the left. 1. Select all German documents from the **All Documents** set and click **Add to Set**. 2. Select "Sick Note DE" from the drop-down list. Repeat the previous step for the remaining documents, selecting "Sick Note BE-NL" from the drop-down list. ## What's next Configure the Extraction Rules activity for German sick notes using search elements.
