A retrospective analysis published by the German Institute for Quality and Efficiency in Health Care (IQWiG) in 2018 concluded that no filter for non-randomized studies (NRS) achieved sufficient sensitivity ([greater than or equal to] 92%), a precondition for comprehensive information retrieval. New NRS filters are therefore required, taking into…

This research improves the precision of information extraction from free-form text via the use of cognitive-based approaches to natural language processing (NLP). Cognitive-based approaches are an important, and relatively new, area of research in NLP and search, as well as linguistics. Cognitive approaches enable significant improvements in both…

Millions of books from public libraries and private collections have been scanned by various organizations in the last decade. The motivation is to preserve the written human heritage in electronic format for durable storage and efficient access. The information buried in these large book collections has always been of major interest for scholars…

The study of this dissertation provides a solution to a very specific problem instance in the area of data mining, data warehousing, and service-oriented architecture in publishing and newspaper industries. The research question focuses on the integration of data mining and data warehousing. The research problem focuses on the development of…

An unprecedented amount of information encompassing almost every facet of human activities across the world is generated daily in the form of zeros and ones, and that is often the only form in which such information is recorded. A good fraction of this information needs to be preserved for periods of time ranging from a few years to centuries.…

The Retrieval of information by means of freely-chosen descriptors may be handled efficiently by creating an inverted file organization in an adaptive manner, entries in this file being generated by sequential searching of the master file, when required. (Author)

This report studies and classifies, according to distinct user-oriented features, the various computer-aided systems developed for storage and retrieval of information in a wide range of fields. Such features are described and evaluated to determine the nature of characteristics that have a strong bearing on the relative success of various query…

The direct-chaining technique of hash coding is generalized in a manner that is useful for storing records on the basis of non-unique search keys. Two hash functions are used, a process implying a tree structure. Two models, one involving unique and the other non-unique keys, are presented. (7 references) (Author/KE)

Describes the "Toronto Globe and Mail" database-the first example of the entire text of a major daily newspaper online, and notes the file elements and possible search strategies. (RAA)

Discusses the basic principles of the application of microfilm (analog) and electronic (digital) technologies for data storage. Image quality is examined, searching and retrieval capabilities are considered, and hardcopy output resolution is described. It is concluded that microfilm is still the preferred archival medium.

The Fort Detrick Information Retrieval System is a system of computer programs written in COBOL for a CDC 3150 to store and retrieve information about the scientific and technical reports and documents of the Fort Detrick Technical Library. The documents and reports have been abstracted and indexed. This abstract, the subject matter descriptors,…

An experiment was conducted to design a corporate author index to a large bibliographic file. The nature of corporate entries necessitates a different search key construction from that of personal names or titles. Derivation of a search key to select distinct corporate entry records is discussed. (7 references) (Author)

Retrospective search of large data bases requires development of special techniques for automatic compression of data and minimization of the number of input-output operations to the computer files. The computer program should require a relatively small amount of internal memory. This paper describes the structure of such a program. (9 references)…

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)
