How this entity was disambiguated
This entity first appeared as the object of triple T8902096 — 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.
NED1
Entity disambiguation (via context triple)
gpt-5-mini-2025-08-07
Target entity: motor cortex Context triple: [primary motor cortex, partOf, motor cortex]
-
A.
primary motor cortex
The primary motor cortex is a brain region in the frontal lobe responsible for the voluntary control and precise execution of skeletal muscle movements.
-
B.
premotor cortex
The premotor cortex is a region of the frontal lobe involved in planning and preparing voluntary movements, integrating sensory information to guide motor actions.
-
C.
supplementary motor area
The supplementary motor area is a region of the medial frontal cortex involved in planning, coordinating, and initiating complex voluntary movements, especially those requiring sequences or bilateral coordination.
-
D.
cerebral cortex
The cerebral cortex is the brain’s highly folded outer layer responsible for complex functions such as perception, language, thought, and voluntary movement.
-
E.
primary somatosensory cortex
The primary somatosensory cortex is a region of the brain’s parietal lobe that processes tactile, proprioceptive, and nociceptive information from the body to create conscious perception of touch and body position.
- 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: motor cortex Description of subject: The motor cortex is a region of the brain’s cerebral cortex responsible for planning, controlling, and executing voluntary movements.
