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).

Target entity: Enantioselective Chemical Synthesis Context triple: [E. J. Corey, hasWritten, Enantioselective Chemical Synthesis]
-
A.
The Logic of Chemical Synthesis
The Logic of Chemical Synthesis is a seminal book by chemist Elias J. Corey that systematically presents the principles and strategies of retrosynthetic analysis for designing complex organic molecule syntheses.
-
B.
Eschenmoser sulfide contraction
Eschenmoser sulfide contraction is an organic rearrangement reaction that converts certain sulfur-containing intermediates into carbonyl compounds, widely used in complex molecule and natural product synthesis.
-
C.
Trost asymmetric allylic alkylation
Trost asymmetric allylic alkylation is a palladium-catalyzed enantioselective carbon–carbon bond-forming reaction that enables the synthesis of chiral molecules from prochiral allylic substrates.
-
D.
Sharpless asymmetric dihydroxylation
Sharpless asymmetric dihydroxylation is a landmark chemical reaction that uses chiral catalysts to add two hydroxyl groups across an alkene with high enantioselectivity, revolutionizing asymmetric synthesis in organic chemistry.
-
E.
Buchwald–Hartwig amination
The Buchwald–Hartwig amination is a palladium-catalyzed cross-coupling reaction that forms carbon–nitrogen bonds by coupling aryl (or vinyl) halides with amines, widely used in the synthesis of pharmaceuticals and fine chemicals.
- 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]"
