Machine-Aided Indexing

Abstract

Progress is reported at the 500,000-word level on the development of a partial syntactic analysis technique for indexing text. The overt error rate at this level is 3.1% (1012 overt errors in 32662 candidate index terms). New and revised indexing subroutines are provided. Computer speed is good. About one million words of text can be indexed in one hour of CPU time.
