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).

Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: the nth Ramanujan prime R_n is the least integer such that for all x ≥ R_n, π(x) − π(x/2) ≥ n
Triple: [Ramanujan prime, definition, the nth Ramanujan prime R_n is the least integer such that for all x ≥ R_n, π(x) − π(x/2) ≥ n]

A Ramanujan prime is a special kind of prime number that guarantees, from a certain point onward, at least a specified number of primes in every interval between x/2 and x.
