PROCEEDINGS OF THE WISWESSER LINE NOTATION MEETING OF THE ARMY CHEMICAL INFORMATION AND DATA SYSTEMS PROGRAM 6-7 OCTOBER 1966

Abstract

A significant application of Wiswesser Line Notation (WLN) is to enable computer discrimination among chemical compounds based on their characteristics as represented by symbolic code designations. These proceedings cover use and techniques of WLN by various industrial, military, and academic organizations. Areas of use discussed include registration of compounds, storage, and retrieval of structures in several collections, and generation of structural fragment codes for rapid structure and substructure searches. Other papers cover quick scan and symbols, a computer-generated open ended fragment code, permutations and classification numbers, the 'Dot-Plot' computer program, and a partial algorithm for development of connection tables from WLN. A presentation on the formal analysis of notation systems is also made. Discussions in techniques include file maintenance and updating procedures, and machine management of small chemical data systems.
