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: SN 1993J
Context triple: [Messier 81, supernovaRecorded, SN 1993J]
  • A. 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.
  • 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 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.
  • D. 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.
  • E. SN 1604
    SN 1604, also known as Kepler's Supernova, was a historically significant stellar explosion observed in 1604 that became one of the brightest recorded supernovae in the Milky Way.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
