How this entity was disambiguated
This entity first appeared as the object of triple T9761817 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: NSKeyedUnarchiver Context triple: [NSCoder, superclassOf, NSKeyedUnarchiver]
-
A.
NSCoder
NSCoder is an abstract class in Apple’s Foundation framework that provides an interface for encoding and decoding objects and values for archiving and serialization.
-
B.
NSData
NSData is a fundamental Objective-C class in Apple’s Foundation framework that represents immutable raw binary data.
-
C.
NSObject
NSObject is the root base class in Objective-C from which most classes in Cocoa and Cocoa Touch inherit, providing fundamental object behavior such as memory management and message sending.
-
D.
Key-Value Observing
Key-Value Observing is an Objective-C and Swift mechanism that lets objects be notified and react when specific properties of other objects change.
-
E.
NSArray
NSArray is an Objective-C class in Apple’s Foundation framework that represents an ordered, immutable collection of objects.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: NSKeyedUnarchiver Description of subject: NSKeyedUnarchiver is a Foundation framework class in Apple’s platforms used to decode and reconstruct objects from archives created by NSKeyedArchiver.
