J(A,B) = |A interseccion B| / |A union B|.	jaccard similarity comparison sets python				false			name desc a primera lista para comparacion name desc b segunda lista para comparacion	coeficiente float de similitud de Jaccard entre 0.0 y 1.0	false			python/functions/cybersecurity/cybersecurity.py

Ejemplo

jaccard_similarity(["a", "b", "c"], ["b", "c", "d"])
# 0.5

jaccard_similarity(["a", "b"], ["a", "b"])
# 1.0

jaccard_similarity([], [])
# 0.0

Notas

Convierte las listas a sets internamente. Retorna 0.0 si ambas listas son vacias. Util para comparar conjuntos de tokens, features de malware, IoCs compartidos entre muestras, o tags de vulnerabilidades.
