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.
Pourbaix diagrams
Pourbaix diagrams are electrochemical charts that map the thermodynamically stable phases and oxidation states of an element in water as a function of pH and electrode potential.
-
B.
Theoretical Structural Metallurgy
Theoretical Structural Metallurgy is a foundational text in materials science that applies theoretical principles to explain the mechanical behavior and structural properties of metals and alloys.
-
C.
Dulong–Petit law for molar heat capacity of many solids at high temperature
The Dulong–Petit law states that many crystalline solids have an approximately constant molar heat capacity of about 3R at sufficiently high temperatures, reflecting classical equipartition of energy among atomic vibrations.
-
D.
Portevin–Le Chatelier effect
The Portevin–Le Chatelier effect is a phenomenon in certain alloys where dynamic strain aging causes serrated yielding and jerky flow during plastic deformation under specific temperature and strain-rate conditions.
-
E.
Cottrell atmosphere
The Cottrell atmosphere is a localized cloud of solute atoms that forms around dislocations in a crystal lattice, reducing their mobility and influencing the material’s mechanical properties.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
