How this entity was disambiguated
This entity first appeared as the object of triple T9931444 — 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.

Shamir secret sharing scheme
The Shamir secret sharing scheme is a cryptographic method that divides a secret into multiple parts so that only a specified threshold of parts can reconstruct the original secret, while fewer parts reveal nothing.

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: Encoding Method for Signature with Appendix – Probabilistic Signature Scheme Description of subject: Encoding Method for Signature with Appendix – Probabilistic Signature Scheme (EMSA-PSS) is a cryptographic message encoding method used with RSA-PSS digital signatures to provide strong security against forgery through probabilistic padding.
