How this entity was disambiguated
This entity first appeared as the object of triple T6328235 — 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.

Target entity: heterotic supergravity Context triple: [Green–Schwarz mechanism, relatedTo, heterotic supergravity]
-
A.
E8×E8 heterotic string theory
E8×E8 heterotic string theory is a ten-dimensional string theory whose gauge symmetry is based on the product of two exceptional Lie groups E8, making it a leading candidate for unifying gravity with the forces and particles of the Standard Model.
-
B.
M-theory
M-theory is a proposed unifying framework in theoretical physics that generalizes string theories into an eleven-dimensional model aiming to reconcile quantum mechanics with gravity.
-
C.
SO(32) heterotic string theory
SO(32) heterotic string theory is a ten-dimensional, anomaly-free string theory whose gauge symmetry group is SO(32), playing a key role in early unified models of fundamental interactions.
-
D.
Green–Schwarz mechanism
The Green–Schwarz mechanism is a key anomaly-cancellation process in string theory that ensures the mathematical consistency of certain superstring models by eliminating gauge and gravitational anomalies.
-
E.
string theory
String theory is a theoretical framework in physics that models fundamental particles as one-dimensional vibrating strings in an attempt to unify quantum mechanics and general relativity.
- 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.
