Linked phrase indexing

摘要

LIPHIS (Linked Phrase Indexing System) is a system of computer-assisted permuted subject indexing designed, like its precursor NEPHIS, to be economical and to be as easy as possible for the indexer, for the programmer, and for the user of the index. Unlike NEPHIS, LIPHIS is designed to handle more complex networks of concept relations, and so produce better indexing of highly detailed subjects.
