A storage and retrieval system for chemical structures, using optical coincidence, is in use at Schering Corp. The system rapidly provides the research laboratories with structural information at any generic level. The design, maintenance, costs, and applications are discussed. (4 references) (Author)

A computer system, named CORA, has been devised for coding chemical structures by fragmentation elements. It has been used to encode Markush formulas in patents according to the Ring codes used in the Ringdoc and Pestdoc services and results in an easy, speedy, reliable and inexpensive method.

Since 1966 the Chemical Society Research Unit in Information Dissemination and Retrieval at the University of Nottingham has been evaluating the use of "Chemical Titles" (CT) and "Chemical-Biological Activities" (CBAC) as current awareness services. Early results of this evaluation led to the Students' Chemical Information…

Part II of the Students' Chemical Information Project (SCIP), designed to spread the use of computer-based information services among research scientists and technologists, contains details of the project operations, statistics, results of questionnaires and research reports from liaison scientists (See LI 002 562 for Part I). Chapter I: Operation…

In a series of meetings held over a period of three days, the National Commission on New Technological Uses of Copyrighted Works (CONTU) heard presentations, arranged by the American Society for Information Science, on information systems in general and on the operations of specific systems. The first presentation covered information storage and…

Describes the construction of expert computer systems using artificial intelligence technology and commercially available software, known as an expert system shell. Provides two applications; a simple one, the identification of seven white substances, and a more complicated one involving the qualitative analysis of six metal ions. (TW)
