Advantages of the Berkeley Mass Storage System (MSS) for information retrieval other than its size are: high serial-read rate, archival data storage; and random-access capability. By use of this device, the search cost in an SDI system based on the Nuclear Science Abstracts" data base was reduced by 20 percent. (6 references) (Author/NH)

IBM's Administrative Terminal System (ATS) is an effective data collection device, but its searching capabilities are severely limited. Searching an ATS document line-by-line is a time consuming process requiring slow printout speeds. A search can operate only upon 9,999 lines of text at any one time. Working storage limitations make it necessary…

The general scope of SPIRAL is storage of free-flowing text information into a machine-readable library and recall of any portions of this stored information that are relevant to an inquiry. The major objectives in the design of the system were (1) to make it easy to use by persons unfamiliar with computer systems; and (2) to make it efficient, in…

The existing volume and increasing growth rate of documented information has resulted in numerous efforts to construct operational Document Storage and Retrieval Systems, as a practical solution to the demand for information storage and retrieval. Accompanying the surge to build more and better and bigger Document Retrieval Systems (DRSs), was the…

Describes ways of using Boolean questions with a clustered information file, and reviews an experiment studying the effect of such a retrieval method. (FM)

Problems encountered in converting a card-oriented biological data information system to new computer equipment are discussed. Data formats, input-output procedures, search strategies, etc., are described. (5 references) (Author/SJ)

A retrospective test search on one year of CA Condensates was carried out in order to calculate the costs per profile and to get an impression of how CA Condensates would suffice as a database for retrospective use. (11 references) (Author)

Northwestern University's Remote Information Query System (RIQS), an information storage and retrieval system characterized by a mixture of data structures for the internal record organization, is discussed. On-line and batch mode search capabilities handle both textual and quantitative information. Other system characteristics, capabilities and…

This paper is aimed at the extension of some results obtained so far concerning information systems design based on qualified parametrical relations. (Author)

An experiment was conducted to identify some of the important parameters affecting search time, a critical cost factor in retrieval systems. Using actual computer searches of Chemical Abstracts Condensate, a comparison was made between the effectiveness of linear and inverted filing systems. Since the results indicated that it was the type and…

INFOL for the CDC 6400 is a rewrite in FORTRAN IV of the CDC 3600/3800 INFOL (Information Oriented Language), a generalized information storage and retrieval system developed by the Control Data Corporation for the CDC 3600/3800 computer. With INFOL, selected pieces of information are extracted from a file and presented to the user quickly and…

The design of an English-like query language and an interactive computer environment for searching the full text of the U.S. patent collection are discussed. Special attention is paid to achieving a transparent user interface, to providing extremely broad search capabilities (including nested substitution classes, Kleene star events, and domain…

SOLAR is an interactive Storage and On-Line Automatic Retrieval system which is operational at Washington State University. It can run continuously with virtually any mix of tasks in a general purpose computing environment. (22 references) (Author)

Presents uniform and efficient approach for processing all truncated query terms in information retrieval which requires one disk access to obtain from the permuted dictionary all strings represented by truncated term. The problem of the overhead storage required to implement the permuted dictionary is discussed. Fifteen references are provided.…

Modeled on public databases such as Lockheed and SDC, the information system described in this report was utilized in the creation of in-house databases in the Mobay Chemical Corporation's special library in Pittsburgh. Using IBM's Storage and Information Retrieval System (STAIRS), Mobay created two databases: one to hold product information, the…
