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.
Haldane–Oparin hypothesis of the origin of life
The Haldane–Oparin hypothesis of the origin of life proposes that life first arose through a gradual chemical evolution of organic molecules in Earth’s early “primordial soup,” eventually leading to self-replicating systems.
-
B.
Luria–Delbrück experiment
The Luria–Delbrück experiment was a landmark 1943 study in bacterial genetics that demonstrated mutations arise randomly rather than in response to selective pressure, providing key evidence for the genetic basis of evolution.
-
C.
Cockcroft–Walton experiment
The Cockcroft–Walton experiment was a pioneering 1932 nuclear physics experiment that achieved the first artificial disintegration of atomic nuclei using accelerated protons, confirming Einstein’s mass–energy equivalence.
-
D.
Meitner–Hahn experiments
The Meitner–Hahn experiments were pioneering nuclear physics investigations in the 1930s that led to the discovery and explanation of nuclear fission in uranium.

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]"
