## Procedure

1. Start Talend Studio.
2. From the top menu bar, select Window > Preferences to open the Preferences window.
3. From the Preferences window, select Talend > Profiling > Semantic-aware analysis.
4. If you modified the port or the cluster name, edit the parameters in the corresponding fields.
5. Click Check Connection to test if you can connect to the repository stored on the Elasticsearch server, and click OK.
6. Create and run a Semantic-aware analysis from the Profiling perspective of Talend Studio to index and enrich the ontology repository on the Elasticsearch server.
