Execute SPARQL queries against the DBpedia knowledge graph via the root endpoint. This is the primary way to extract structured data from Wikipedia articles. The endpoint supports SELECT queries for tabular data, ASK for boolean results, DESCRIBE for resource descriptions, and CONSTRUCT for building new RDF graphs. Results are returned in SPARQL JSON format by default. Use this when you need to find specific facts across DBpedia's millions of entities - for example, finding all scientists born in a particular city, or retrieving labels and abstracts for a specific resource. The query parameter is URL-encoded and required.
