Target entity: Lewy body dementia Context triple: [Robin Williams, diagnosedWith, Lewy body dementia]
-
A.
Parkinson's disease
Parkinson's disease is a progressive neurodegenerative disorder characterized primarily by motor symptoms such as tremors, rigidity, and slowed movement, caused by the loss of dopamine-producing neurons in the brain.
-
B.
Lewy bodies
Lewy bodies are abnormal aggregates of the protein alpha-synuclein that accumulate inside neurons and are characteristic of Parkinson’s disease and related neurodegenerative disorders.
-
C.
Alzheimer's disease
Alzheimer's disease is a progressive neurodegenerative disorder characterized by memory loss, cognitive decline, and behavioral changes, and is the most common cause of dementia in older adults.
-
D.
Huntington's chorea
Huntington's chorea is a hereditary neurodegenerative disorder characterized by progressive motor dysfunction, cognitive decline, and psychiatric symptoms, typically manifesting in mid-adulthood.

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: Lewy body dementia Description of subject: Lewy body dementia is a progressive neurodegenerative disorder characterized by cognitive decline, visual hallucinations, fluctuating alertness, and Parkinsonian movement symptoms, caused by abnormal protein deposits called Lewy bodies in the brain.
