olemus
ISO/IEC/IEEE 24765, ISO/IEC 2382:
arvutisüsteem, mis aitab asjatundlikult
lahendada probleeme mingis valdkonnas või rakendusalal,
tehes järeldusi teadmusbaasist,
mis on rajatud inimkogemuste alusel,
võib olla võimeline seda teadmusbaasi täiendama
ja töötama välja uusi järeldusreegleid
eelmiste probleemidega saadud kogemuse põhjal
= computer system that provides for expertly solving problems in a given field or application area by drawing inferences from a knowledge base developed from human expertise
Note. Some expert systems are able to improve their knowledge base and develop new inference rules based on their experience with previous problems.

ISO/IEC 22989:
tehisarusüsteem, mis probleemilahenduste tuletamiseks akumuleerib, ühendab ja kapseldab teadmust, mida ta saab spetsiifilise valdkonna asjatundja(i)lt
= AI system that accumulates, combines and encapsulates knowledge provided by a human expert or experts in a specific domain to infer solutions to problems
