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).

Input

Phrase: Frequency Division Duplex | Statement: [FDD, abbreviationFor, Frequency Division Duplex]

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Frequency Division Duplex
Context triple: [FDD, abbreviationFor, Frequency Division Duplex]

A. Time Division Duplex
Time Division Duplex is a wireless communication method that uses a single frequency band for both uplink and downlink by separating them in time rather than frequency.
B. OFDMA
OFDMA (Orthogonal Frequency Division Multiple Access) is a multi-user version of OFDM that divides subcarriers among multiple users to enable efficient, high-capacity wireless communication in systems like LTE and WiMAX.
C. SC-FDMA
SC-FDMA (Single-Carrier Frequency Division Multiple Access) is a multi-carrier transmission scheme used primarily in LTE uplink that combines single-carrier characteristics with frequency-domain equalization to achieve lower peak-to-average power ratio than OFDM.
D. OFDM
OFDM (Orthogonal Frequency-Division Multiplexing) is a digital multi-carrier modulation technique that splits data across many closely spaced orthogonal subcarriers to improve robustness against interference and multipath fading in wireless and wired communication systems.
E. Time Division Multiple Access
Time Division Multiple Access (TDMA) is a channel access method that divides a communication medium into time slots so multiple users can share the same frequency without interference.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
