How this entity was disambiguated
This entity first appeared as the object of triple T4979789 — 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.

Entity disambiguation (via context triple)
gpt-5-mini-2025-08-07
Target entity: TLS 1.2 Context triple: [RFC 7465, appliesTo, TLS 1.2]
-
A.
TLS 1.1
TLS 1.1 is an older version of the Transport Layer Security protocol that improved upon earlier SSL standards but has since been deprecated in favor of more secure versions like TLS 1.2 and 1.3.
-
B.
TLS 1.0
TLS 1.0 is an early version of the Transport Layer Security protocol used to secure communications over computer networks, now largely deprecated in favor of more secure later versions.
-
C.
SSL 2.0
SSL 2.0 is an early, now-obsolete version of the Secure Sockets Layer protocol that provided encrypted communication over networks before being replaced by more secure successors like TLS.
-
D.
TLS
TLS (Transport Layer Security) is a cryptographic protocol that secures data transmitted over networks by providing encryption, authentication, and integrity between communicating applications.
-
E.
TLS
TLS is the IATA airport code for Toulouse-Blagnac Airport, the main international airport serving Toulouse in southwestern France.
- 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: TLS 1.2 Description of subject: TLS 1.2 is a widely deployed version of the Transport Layer Security protocol that provides encrypted and authenticated communication over computer networks.
