 ## Entity Linking
 
 Create an array of strings containing the document you want to analyze. Call the client's `recognizeLinkedEntities()` method and get the `RecognizeLinkedEntitiesResult` object. Iterate through the list of results, and print the entity name, ID, data source, url, and matches. Every object in `matches` array will contain offset, length, and score for that match.
