indicateur de rôle

CONT: «l'indexateur» doit transformer les indicateurs de rôles en codes de manipulation que l'ordinateur interprète selon un programme.

OBS: PRECIS (preserved context indexing system) format is designed to preserve each of these concepts in its context. Each verbalisation is called a 'term'; these terms are assigned 'role operators': single integers or letters which represent the syntactical functions of the terms. (C.B. Newsletter, no. 7, March 1973, p. 11)
