A preserved context indexing system for microcomputers: PERMDEX

摘要

PERMDEX is a microcomputer program to assist in the creation of a permuted printed index which preserves the context of indexing paraphrases. Although much simpler than PRECIS, the microcomputer program was inspired by it, and uses role operators to permute terms through lead, qualifier, and display positions. Following a discussion of derivative vs assignment indexing, the use of roles, and the concept behind PRECIS, features of the program are described including indexer input and prompts, the shunting algorithm, and sorting and printing routines.
