How this entity was disambiguated
This entity first appeared as the object of triple T4835364 — 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: Milky Way globular cluster system Context triple: [Messier 22, partOf, Milky Way globular cluster system]
-
A.
Milky Way open cluster system
The Milky Way open cluster system is the collective population of loosely bound star clusters within our galaxy, formed from the galactic disk’s molecular clouds and serving as key tracers of its structure, star formation history, and chemical evolution.
-
B.
Milky Way stellar halo
The Milky Way stellar halo is a vast, diffuse, roughly spherical population of old, metal-poor stars and dark matter that surrounds the Milky Way’s disk and bulge, extending far into its outer regions.
-
C.
Canis Major Overdensity
The Canis Major Overdensity is a debated stellar overdensity near the plane of the Milky Way, often interpreted as either the remnant core of a disrupted dwarf galaxy or a warp/flare feature of the Galactic disk.
-
D.
Milky Way subgroup
The Milky Way subgroup is the collection of nearby galaxies gravitationally bound to and dominated by the Milky Way within the larger Local Group.
-
E.
Coming of Age in the Milky Way
Coming of Age in the Milky Way is a popular science book that traces the historical development of our understanding of the universe, blending astronomy, physics, and cultural history for a general audience.
- 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: Milky Way globular cluster system Description of subject: The Milky Way globular cluster system is the population of ancient, densely packed star clusters that orbit the Milky Way’s halo and bulge, serving as key tracers of the galaxy’s formation and evolution.
