CE ÎNSEAMNĂ DICHOTOMOUS KEY ÎN ENGLEZĂ?
Tasta cu acces unic
O cheie cu acces unic este o cheie de identificare în care secvența și structura pașilor de identificare sunt fixate de autorul cheii. La fiecare punct al procesului decizional, sunt oferite mai multe alternative, fiecare conducând la un rezultat sau la o altă alegere. Alternativele sunt denumite în mod obișnuit "conduce", iar setul de conductori la un anumit punct este un "cuplet". Tastele cu acces unic sunt strâns legate de copacii de decizie sau de arborii binari de auto-echilibrare. Cu toate acestea, pentru a îmbunătăți gradul de utilizare și fiabilitatea cheilor, multe chei cu acces unic încorporează reticularea, schimbând structura copacului într-un grafic aciclic direcționat. Taste cu acces unic au fost utilizate pentru câteva sute de ani. Acestea pot fi imprimate în diferite stiluri sau utilizate ca chei interactive, asistate de calculator. În acest din urmă caz, fie o parte mai lungă a cheii poate fi afișată, fie o singură întrebare poate fi afișată la un moment dat. Dacă cheia are mai multe opțiuni, ea este descrisă ca polochotomă sau politoasă. Dacă întreaga cheie constă din exact două opțiuni la fiecare punct de ramificare, cheia este numită dichotom. Majoritatea cheilor cu acces unic sunt dihotomice.
