A procedure for automated indexing of pathology diagnostic reports at the National Institute of Health is described, including a discussion of English terms encoded into the Systematized Nomenclature of Pathology (SNOP)--a manual indexing language--resulting in effective automatic encoding. Morphosyntactic analysis and synonym substitutions are…

Describes the optical digital disk, which stores machine-readable information in digitized form, and discusses their production, cost, present and future applications. The major companies currently active in the disk field are noted. (MBR)

The Lister Hill National Center for Biomedical Communications has supported a program to develop a Plasma Terminal System for purposes of improving the effective delivery of computer based educational materials. This system, employing recent advances in microprocessing and storage technologies, will provide new alternatives for present users of…

Investigates applicability of inverted file processing in magnetic bubble memories by presenting four magnetic bubble memory models as storage mediums: one based on a major-minor loop configuration; one utilizing a decoder design on a magnetic bubble memory chip; and two based on different structural configurations of the first two. (MBR)

Reviews computer storage devices designed to provide additional memory for microcomputers--chips, floppy disks, hard disks, optical disks--and describes how secondary storage is used (file transfer, formatting, ingredients of incompatibility); disk/controller/software triplet; magnetic tape backup; storage volatility; disk emulator; and…

An analysis of computer-based search services (ISSs) from a system's viewpoint, using a continuous simulation model to reveal growth and stagnation of a typical system is presented, as well as an analysis of decision making for an ISS. (Author/MBR)
