Seven-of-Nine

Our class discussion today put me in mind of Star Trek: Voyager and the character Seven-of-Nine. Is she human? She was as a child, but then assimilation into the Borg did something to her that causes her to function in many "automated" ways that are sort of Vulcan-like and Data-like at the same time. Does she have a soul? How might it have been affected by the Borg?
