Klopfenstein, D. V.; Dampier, Will – Research Synthesis Methods, 2021
We read with considerable interest the study by Gusenbauer and Haddaway (Gusenbauer and Haddaway, 2020, Research Synthesis Methods, doi:10.1002/jrsm.1378) comparing the systematic search qualities of 28 search systems, including Google Scholar (GS) and PubMed. Google Scholar and PubMed are the two most popular free academic search tools in biology…

Delaney, Aogán; Tamás, Peter A. – Research Synthesis Methods, 2018
Despite recognition that database search alone is inadequate even within the health sciences, it appears that reviewers in fields that have adopted systematic review are choosing to rely primarily, or only, on database search for information retrieval. This commentary reminds readers of factors that call into question the appropriateness of…

Gusenbauer, Michael; Haddaway, Neal R. – Research Synthesis Methods, 2021
We researchers have taken searching for information for granted for far too long. The COVID-19 pandemic shows us the boundaries of academic searching capabilities, both in terms of our know-how and of the systems we have. With hundreds of studies published daily on COVID-19, for example, we struggle to find, stay up-to-date, and synthesize…

Dadlez, Eva M. – Database, 1984
Describes a natural language searching strategy for retrieving current material which has bearing on George Orwell's "1984," and identifies four main themes (technology, authoritarianism, press and psychological/linguistic implications of surveillance, political oppression) which have emerged from cross-database searches of the "Big…

Burger, Robert H. – Library Journal, 1983
Discussion of the process of library cataloging notes the 8th century cataloger, Alcuin; purpose of cataloging; bibliographic control; access to information; cataloging on OCLC; emphasis on the format in which cataloging information is communicated; lost precision; authority files; and recall versus precision. Seven references are included. (EJS)

Rajashekar, T. B.; Croft, W. Bruce – Journal of the American Society for Information Science, 1995
Describes a system based on a probabilistic inference network retrieval model that was used to study the retrieval effectiveness benefits of combining types of document and query information that are found in typical commercial databases and information services. Multiple document representations, multiple index representations, and multiple query…

Heine, M. H.; Tague, J. M. – Journal of the American Society for Information Science, 1991
Discussion of the role of Boolean logic in the information retrieval process focuses on a study that investigated the optimization of search logic for the MEDLINE database. Measures of retrieval effectiveness are discussed, the relationship of weighting schema and the logical schema is considered, and further investigations are suggested. (17…

Wilbur, W. John; Coffee, Leona – Information Processing and Management, 1994
Compares two methods of information retrieval--one that rates documents according to a query and another that uses relevant documents to find further relevant documents (i.e., neighboring documents). Highlights include experiments at the National Library of Medicine; feedback; vector cosine retrieval; and a measure of retrieval effectiveness…

Chen, Patrick Shicheng – Information Processing and Management, 1994
Discussion of relevance and the needs of the users in information retrieval focuses on a deductive object-oriented approach and suggests eight inference rules for the deduction. Highlights include characteristics of a deductive object-oriented system, database and data modeling language, implementation, and user interface. (Contains 24…

Perez, Ernest – Special Libraries, 1982
Discusses the quality of information retrieval using "free text" searching in full-text databases and presents a critical perspective on the importance of augmenting access to full-text databases through some form of text enhancement, such as the use of a limited controlled vocabulary for indexing general concepts. (Author/JL)

Cleverdon, Cyril – Information Services and Use, 1984
Discusses alternatives to the Boolean system that would enable users of online bibliographic databases--primarily those containing scientific and technical information--to obtain their required level of performance at lowest cost. Highlights include recall and precision factors (natural and controlled language, titles, abstracts, quorum function)…

Robbins, Simone B. – Database, 1985
Discusses the inclusion of citations to literary articles that have appeared in medical journals in National Library of Medicine's database, MEDLINE. Highlights include search aids, search strategies, sample references, and five publications that serve as orientations to current status of movement toward interdisciplinary study of medicine and…

Sillince, J. A. A. – Online Review, 1992
Argues that information retrieval based on semantic representation is not helpful for those searchers who do not have well-defined ideas of the target document type. Presents an alternative, complementary method for indexing and document retrieval based on attributes of argumentation, a characteristic of articles advancing a claim. (52 references)…

Salton, Gerald – Information Processing and Management, 1992
The current state of information retrieval (IR) evaluation is reviewed with criticisms directed at the available test collections and the research and evaluation methodologies used, including precision and recall rates for online searches and laboratory tests not including real users. Automatic text retrieval systems are also discussed. (32…

Blair, David C. – Information Processing and Management, 1986
Discusses indeterminancy of selection of terms by indexers and by inquirers as major factors influencing subject access to documents in document retrieval systems. Five types of interactions between these two indeterminancies are discussed, and a change in traditional method of subject searching is suggested to reduce effect of inter-indexer…
