The tag alias #52287 ai_core_(portal) -> personality_core_(portal) has been approved.
Reason: These refer to the same thing, and only appear separately on one image on e6.
The only exception is that ai core (portal) may have a broader implication and include other Artificial Intelligences like turrets and GlaDOS. Though, turrets already have their own tag: turret (portal)
EDIT: The tag alias ai_core_(portal) -> personality_core_(portal) (forum #312543) has been approved by @bitWolfy.
