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: the "Reflections on Trusting Trust" lecture and paper Description of subject: "Reflections on Trusting Trust" is Ken Thompson’s influential 1984 Turing Award lecture and paper that exposed how a compiler could be maliciously modified to invisibly insert security vulnerabilities, fundamentally shaping thinking about software trust and supply-chain security.
