a semi automatic is a gun that can fire one bullet, unlock and move the bolt/breech back, cock the hammer, take the next round from the magazine (or stripper clip as in the case of an M1 Garand), rechamber the round of ammunition and close (and lock) the breech so the firearm may be fired again with the next squeeze of the trigger. There are a number of ways to do this. In .22, .25, .380 handguns operate by simple blowback. 9mm, 30Mauser, 45ACP, etc are recoil operated with a locking breech - rifles are usually gas operated.
A rifle with a revolver cylinder is usually not called semiautomatic, revolvers are simply called revolvers.
