hey aspirant,
autonomous government colleges are colleges which are given freedom to design their own curriculum and conduct their own exams and open campus in various other places. Once these colleges become an autonomous institution they become a deemed university ie. then they can offer various other courses and even PG courses whereas semi-government colleges are half private and half government .They are known as society colleges as well (different from deemed one's) These colleges are not directly run by government but under the control of government that is not government owned but government aided. so directly there is no connection between both the type collges.
hope it helps..
