# tagHypothesesAtIndex:unit:scheme:maximumCount:tokenRange: Finds multiple possible tags for a given linguistic unit, for a single scheme, at the specified character position. ``` - (NSDictionary *) tagHypothesesAtIndex:(NSUInteger) characterIndex unit:(NLTokenUnit) unit scheme:(NLTagScheme) scheme maximumCount:(NSUInteger) maximumCount tokenRange:(NSRangePointer) tokenRange; ``` ## Parameters `characterIndex` The character index to begin examination. `unit` The linguistic unit. See [`NLTokenUnit`](/documentation/NaturalLanguage/NLTokenUnit) for possible values. `scheme` The tag scheme. See [`NLTagScheme`](/documentation/NaturalLanguage/NLTagScheme) for possible values. Not all tag schemes produce more than one prediction. `maximumCount` The maximum number of tag predictions to return. `tokenRange` The range of the token for which the tags were produced. ## Return Value A tuple containing a dictionary and a range. ## Discussion Each dictionary entry is a predicted tag with its associated probability score. These tags are the top candidates proposed as possible tags for the token. The dictionary contains up to `maximumCount` entries. The range contains the range of the individual token for which these tags were produced. --- Copyright © 2026 Apple Inc.
