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: SN 1923A Context triple: [Messier 83, supernovaeObserved, SN 1923A]
-
A.
SN 1993J
SN 1993J is a well-studied Type IIb supernova that occurred in the nearby galaxy Messier 81 and became one of the brightest and most extensively observed supernovae of the late 20th century.
-
B.
SN 1987A
SN 1987A is a famous supernova, the closest observed in modern times, whose 1987 explosion in the Large Magellanic Cloud has provided key insights into stellar death and supernova physics.
-
C.
SN 2004dj
SN 2004dj is a relatively nearby Type II-P supernova discovered in 2004 in the spiral galaxy NGC 2403, notable for being one of the brightest and closest core-collapse supernovae observed in recent decades.
-
D.
SN 1961V
SN 1961V is a peculiar and debated astronomical transient in the galaxy NGC 1058, long argued to be either an unusual supernova or a super-outburst of a luminous blue variable star.
-
E.
SN 1572
SN 1572 is a historically significant supernova in the constellation Cassiopeia whose detailed observations by Tycho Brahe helped challenge the Aristotelian view of an unchanging heavens.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
