贾维斯 most often refers to J.A.R.V.I.S. — Tony Stark's AI assistant in Marvel's Iron Man films, whose name in the comics stands for 'Just A Rather Very Intelligent System' and is a tribute to butler Edwin Jarvis. The translit pattern is
贾 (Jia, surname) +
维 ('wei') +
斯 ('s'), giving Jia-wei-s ≈ Jar-vi-s.
