NER
Named-entity recognition
gpt-5-mini
Instruction
Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

-
A.
Molten-Salt Reactor Experiment at Oak Ridge
The Molten-Salt Reactor Experiment at Oak Ridge was a pioneering 1960s nuclear research reactor that demonstrated the feasibility of using molten salt as both fuel and coolant, significantly advancing concepts for safer and more efficient nuclear power.
-
B.
Sodium Reactor Experiment
The Sodium Reactor Experiment was an early U.S. experimental nuclear power reactor that became notable as the first in the country to supply electricity to a commercial power grid and for a significant 1959 partial meltdown incident.
-
C.
S2W nuclear reactor
The S2W nuclear reactor was an early U.S. Navy pressurized water reactor design that powered the world’s first operational nuclear-powered submarine, USS Nautilus.
-
D.
Thermal Oxide Reprocessing Plant
The Thermal Oxide Reprocessing Plant is a major nuclear facility at Sellafield in the UK that was used to reprocess spent nuclear fuel from reactors, recovering usable materials such as uranium and plutonium.
-
E.
X-10 graphite reactor
The X-10 graphite reactor was an early nuclear reactor at Oak Ridge, Tennessee, built during the Manhattan Project as a pilot plant for plutonium production and a key step toward the development of nuclear weapons and nuclear energy.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
NEDg
Description generation
gpt-5.1
Instruction
Generate a one-sentence description of the target entity. You are given a context triple in the form (subject, predicate, object), where the object is the target entity. # Instructions Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. Avoid repeating the information from the triple, unless really essential. # Response Format Return only the sentence: "Description: [one-sentence description of the target entity]"
