How this entity was disambiguated
This entity first appeared as the object of triple T1966327 — 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.

Entity disambiguation (via context triple)
gpt-5-mini-2025-08-07
Target entity: Cambrian biota Context triple: [Ediacaran biota, precedes, Cambrian biota]
-
A.
Ediacaran biota
The Ediacaran biota comprises some of the earliest known complex multicellular organisms, featuring soft-bodied, enigmatic life forms that lived in the oceans before the Cambrian explosion.
-
B.
Cambrian explosion
The Cambrian explosion was a relatively brief period around 541 million years ago when most major animal groups rapidly appeared in the fossil record, dramatically increasing the complexity and diversity of life on Earth.
-
C.
Cambrian Period
The Cambrian Period was an early division of geologic time marked by a rapid diversification of life known as the "Cambrian explosion," during which most major animal groups first appeared in the fossil record.
-
D.
Great Ordovician Biodiversification Event
The Great Ordovician Biodiversification Event was a profound evolutionary radiation during the Ordovician Period that saw a dramatic increase in marine biodiversity and the establishment of many major animal groups in Paleozoic oceans.
-
E.
Paleozoic Era
The Paleozoic Era was an ancient geologic time interval, spanning roughly 541 to 252 million years ago, marked by the emergence and diversification of complex life in the seas and on land and the assembly of major continental landmasses.
- 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: Cambrian biota Description of subject: The Cambrian biota comprises the diverse and rapidly evolving array of animal life that appeared during the Cambrian explosion, marking a major expansion in complexity and the emergence of most major animal groups.
