# Running the Classification To start the classification, press the *Classify Ontology* button in the main toolbar. The reasoner now evaluates the defining relationships between the concepts to infer new connections and identify unnecessary or redundant ones. Afterward, an ontology-comparison process calculates the changes that the reasoner found between the old and the new ontology.

Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.b2ihealthcare.com/snow-owl-authoring-platform/description-logic/running-the-classification.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
