3. Lastnosti - Pattie Maes opazuje uporabnika dobiva povratne informacije od uporabnika dobiva neposredna navodila od uporabnika pridobiva izkušnje iz okolja agent in uporabnik komunicirata, nadzorujeta, izvajata opravila se uci glede na interese, navade in želje uporab.

4. Lastnosti - Etzioni avtonomija pri izvajanju opravil: sprejema zahtevne naloge od uporabnika, modificira zahteve, izvaja prilagodljiva opravila, sam zacne izvajati opravila casovna kontinuiteta - stalno deluje osebnost zmožnost komunikacije prilagodljivost uporabniku mobilnost

5. “Simple rules” does it perform typical user-oriented functions (insurance agent) autonomy - performs actions on its own (yes) - is prediction of actions possible (no) adapts to each specific user - different reactions for the same error works all the time, looks around (mobile) data - information - knowledge

6. Lastnosti agentov dokaj splošne definicije - noben sistem nima vseh lastnosti agentov - sistemi imajo vec ali manj lastnosti agentov - meja ni tocno definirana “agent” je nekoliko drugacen program podobne relacije: nestrukturno > strukturno programiranje; modularno > objektno; informacijski sistemi > ekspertni sistemi; podatki > informacije > znanje

7. Kategorije agentov; Etzioni sovozniki v taksiju - svetujejo, kje zaviti voznik taksija, ki pelje po navodilih uporabnika tajnica oz. asistent, ki sprejme nalogo in jo samostojno izvede
