How this entity was disambiguated
This entity first appeared as the object of triple T2184529 — 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: IERS Conventions Context triple: [International Earth Rotation and Reference Systems Service, publishes, IERS Conventions]
-
A.
International Celestial Reference System
The International Celestial Reference System is the standard, high-precision coordinate framework used in astronomy and geodesy to define positions of celestial objects relative to distant quasars.
-
B.
Earth Orientation Parameters
Earth Orientation Parameters are a set of time-varying values that precisely describe the irregular rotation and orientation of the Earth in space for applications like navigation, astronomy, and geodesy.
-
C.
International Earth Rotation and Reference Systems Service
The International Earth Rotation and Reference Systems Service (IERS) is an international organization that monitors Earth's rotation and maintains global reference systems used for precise timekeeping, navigation, and geodesy.
-
D.
International Terrestrial Reference System
The International Terrestrial Reference System is a globally standardized, Earth-centered coordinate framework used for precise positioning, navigation, and geodetic measurements.
-
E.
International VLBI Service for Geodesy and Astrometry
The International VLBI Service for Geodesy and Astrometry is an international organization that coordinates Very Long Baseline Interferometry observations to provide precise measurements of Earth’s rotation, reference frames, and celestial positions.
- 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: IERS Conventions Description of subject: IERS Conventions are a set of internationally recognized technical standards and models that define how to precisely measure and reference Earth’s rotation, orientation, and reference frames for geodesy and astronomy.
