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).

“Superacids” is a landmark chemistry book by George A. Olah that systematically explores extremely strong acids and their role in stabilizing carbocations and enabling unusual chemical reactions.
-
C.
Lewis acid–base theory
Lewis acid–base theory is a chemical framework that defines acids as electron-pair acceptors and bases as electron-pair donors, broadening the concept of acid–base reactions beyond proton transfer.
