How this entity was disambiguated
This entity first appeared as the object of triple T244260 — 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.

gpt-5-mini-2025-08-07
Target entity: special relativity Context triple: [Lorentz transformation, partOf, special relativity]
-
A.
theory of relativity
The theory of relativity is a fundamental framework in physics, developed by Albert Einstein, that revolutionized our understanding of space, time, gravity, and motion.
-
B.
relativity of simultaneity
Relativity of simultaneity is the special relativity principle that events judged simultaneous in one inertial frame may occur at different times in another moving frame, showing that simultaneity is not absolute.
-
C.
Lorentz contraction
Lorentz contraction is the special relativistic effect in which an object’s length along the direction of motion appears shortened to observers in a different inertial frame moving at high relative velocity.
-
D.
Minkowski space-time
Minkowski space-time is a four-dimensional geometric framework that unifies three-dimensional space and time into a single continuum used to describe events and motion in special relativity.
-
E.
Lorentz transformation
The Lorentz transformation is a set of equations in special relativity that relate space and time coordinates between two inertial reference frames moving at a constant velocity relative to each other, ensuring the constancy of the speed of light.
- 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: special relativity Description of subject: Special relativity is Einstein’s theory of space and time that explains how measurements of distance, duration, and simultaneity depend on the relative motion of observers moving at constant velocities.
