How this entity was disambiguated
This entity first appeared as the object of triple T4332160 — 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: Pulmonary valve Context triple: [Heart, hasPart, Pulmonary valve]
-
A.
Tricuspid valve
The tricuspid valve is one of the heart’s four valves that regulates blood flow between the right atrium and right ventricle, preventing backflow during ventricular contraction.
-
B.
Mitral valve
The mitral valve is a dual-flap heart valve between the left atrium and left ventricle that ensures one-way blood flow from the atrium to the ventricle.
-
C.
Pulmonary artery
The pulmonary artery is the large blood vessel that carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation.
-
D.
Right ventricle
The right ventricle is one of the heart’s four chambers that pumps deoxygenated blood to the lungs via the pulmonary artery.
-
E.
Atrial septum
The atrial septum is the wall of tissue that separates the heart’s left and right atria, helping maintain proper direction and separation of blood flow between them.
- 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: Pulmonary valve Description of subject: The pulmonary valve is one of the heart’s four valves that controls blood flow from the right ventricle into the pulmonary artery and prevents backflow into the heart.
