Dichotomous Key
Method for determining the identity of a specimen (whether organic in organic, rl or vir) by proceeding through a series of choices, leading to the correct identification of the item. At each step of the process, the user is given two choices; each alternative leads to another questions until the identification is complete, assuming the specimen is in the database used to make the key and assuming that each yes/no question can be answered in an unambiguous way. Nonsentient expert ai systems may make extensive use of such keys.
