“…A fall-back position lay in investigating a more appropriate, low-technology option, that of providing assistance to indexers by allowing them to record indexing phrases, and having the machine undertake the more routine work of producing the entries appropriate for each subject heading. This was done by applying articulation automatically in order to produce the entries, and sorting and arranging them for display in a well-organized printed index [17][18][19][20]60]. The method is applicable not merely to chemistry but to any subject matter, but has little applicability in languages other than Enghsh.…”

This paper discusses research which was carried out at the Department of Information Studies, University of Sheffield in the period 1965 to 1985 into storage and retrieval techniques for databases of textual and chemical structure data. The research includes the development of methods for the automatic production of printed subject indexes and for the indexing and retrieval of chemical structures and chemical reactions, the variety generation method for the analysis, characterization and storage of data in a range of types of textual database, the prediction of biological activity in chemical compounds, and the design of document retrieval systems.the textual context [47]. In large part, these similarities of application arise from the frequency distributions underlying these two types of data, a factor which has become clear from the studies described in Sections 4 and 5 of tlus paper.

NEPHIS is a system of computer‐aided permuted subject indexing designed to be an easy as possible for the indexer, for the programmer, and for the user of the index. The indexer needs to learn only four commands in order to be able to construct any input string. Yet the permutations produced are elegant and browsable, while providing a complete description of even quite complicated subjects. The program is cheap to run, requiring only an input file and an output file and 1K of core.

Simple automatic coding of most descriptive titles generates NEPHIS (NEsted PHrase Indexing System) input strings of sufficiently good quality for permuted in. dex production. The coding algorithm is based on assumptions about three ranks of delimiter, and about phrase-element dependency, in title language; NEPHIS facilitates human recoding of the few titles violating these assumptions. Initially implemented in DECsystem-10 DPL, but applicable also to microcomputer systems, the algorithm requires only brief lists of delimiters plus an input set containing one or more titles; stoplisting is optional.
