This research identifies the similarities and differences between the MathSciNet search features and functions of the American Mathematical Society (AMS) and EBSCOhost platforms. A series of iterative MathSciNet queries were performed on both platforms. For each query, the total number of results and search behavior were documented and analyzed.…

Objective: The objective of this study was to investigate the impact of the peer review of literature search strategies prepared in support of rapid reviews. Methods: A sample of 200 CADTH rapid reviews was selected. For each rapid review meeting the inclusion criteria, the pre-peer-reviewed and corresponding post-peer-reviewed search strategies…

Due to the large volume and exponential growth of biomedical documents (e.g., books, journal articles), it has become increasingly challenging for biomedical search engines to retrieve relevant documents based on users' search queries. Part of the challenge is the matching mechanism of free-text indexing that performs matching based on…

Searches for 117 British authors are compared in the Annual Bibliography of English Language and Literature (ABELL) and the Modern Language Association International Bibliography (MLAIB). Authors are organized by period and genre within the early modern era. The number of records for each author was subdivided by format, language of publication,…

Purpose: The paper aims to assess the utility of non-agriculture-specific information systems, databases, and respective controlled vocabularies (thesauri) in organising and retrieving agricultural information. The purpose is to identify thesaurus-linked tree structures, controlled subject headings/terms (heading words, descriptors), and principal…

Designed to provide students of information science with an introduction to British librarian Samuel Clement Bradford's 1934 findings about the scattering of information, this reader on Bradford's Law begins by discussing its use in calculating search procedures in printed bibliographies as well as in databases. The following additional materials…

Presents a set-oriented view of information retrieval and defines a precise model to capture this approach. A number of consequences of the model, such as the limitations implied by a finite index vocabulary, are examined, and the various ways in which the set orientation can influence thinking about information retrieval is discussed. (14…

Discusses previous research that examined the effects of different kinds of vocabulary control on retrieval effectiveness, and describes a study that addressed the effects of indexing depth on standard retrieval evaluation measures in the context of a typical commercial retrieval system. It is concluded that controlled vocabularies affect…

Describes a project that was designed to test the relative efficacy of index terms and full-text for the retrieval of documents in MEDLINE journals. Precision and relevance of citations retrieved from full-text databases versus bibliographic databases is discussed, and the addition of MEDLINE indexing to enhance full-text medical journals is…

Discussion of the information-seeking behavior of humanists focuses on a study that investigated the efficacy of following bibliographic references from documents already known. Topics include the nature of humanities research; vocabulary control and indexing; subject-based literature searches; seed documents; relevance; retrieval based on…

Provides an overview of the problems with information retrieval in psychology, based on the examination of the search strategy used for a dissertation. The discussion illustrates the usefulness of a facet model for formulating search strategies for psychology literature reviews, using the same dissertation as an example. (15 references) (CLB)

Discussion of information retrieval in the humanities focuses on a study of 10 graduate students at Indiana University as they conducted literature searches using databases on CD-ROM. Highlights include a review of related literature, search strategies, relevance assessments, human-computer interaction, and databases and indexing. (LRW)

Presents a general overview of the development of Information Science Abstracts. The historical perspective, including the contributions of individuals and institutions, is discussed; its coverage is compared with that of other information science databases; and retrieval capabilities are described. (four references) (Author/CLB)

Describes methods for applying natural-language processing for automatic concept-based indexing of full text and methods for exploiting the structure and hierarchy of full-text documents to a large collection of full-text documents drawn from the Health Services/Technology Assessment Text database at the National Library of Medicine. Examines how…

This test of the Strategy of Unlimited Aliasing, an indexing method that places terms from several indexers for the same information object in one index, utilized bibliographic records from the ERIC, LISA (Library and Information Science Abstracts), and ISA (Information Science Abstracts) databases. The test did not support the indexing method.…
